Chains

Performance chains are the critical link between your engine's power output and the driven wheel or sprocket — and at Motor Sport Mayhem, we stock 554 chain options across 92 brands, covering everything from budget-friendly street replacements to hardened race-spec drive chains built to survive sustained high-RPM abuse. Chain quality directly determines power transfer efficiency, longevity under load, and resistance to stretch under the aggressive acceleration cycles that destroy OEM components prematurely.

Our Top Picks for Chains

These products were hand-selected by our performance specialists based on verified real-world results, engineering quality, and application range across street, track, and competition builds.

How to Choose the Right Chains

The single most important decision when selecting a performance drive chain is matching the chain's rated tensile strength and seal type to the actual operating conditions — not just the stock power figure. OEM chains are designed to minimum-cost tolerances; they stretch prematurely, shed lubrication rapidly, and fail early when subjected to the shock loading of aggressive acceleration or the sustained high-RPM operation of competition use. Aftermarket chains are differentiated primarily by construction quality: pin and plate material hardness, seal ring type (O-ring, X-ring, or Z-ring), inner link plate geometry, and the consistency of dimensional tolerances from link to link. A poorly toleranced chain — even a nominally "heavy duty" one — introduces micro-variation in pitch that accelerates sprocket wear and creates power-robbing drivetrain vibration.

Key Specifications

Tensile strength is the foundational specification: it defines the maximum load the chain can sustain before failure. For street performance applications, a minimum tensile strength of 8,500 lbs on a standard 520-pitch chain is a reasonable benchmark. Racing applications — particularly drag racing — demand chains rated well above peak drivetrain torque loads with a safety margin that accounts for shock loading at launch, which can momentarily multiply effective chain tension by a factor of three or more compared to steady-state running.

Seal type determines lubrication retention and service life. Standard unsealed roller chains are lightweight and efficient but require frequent lubrication and wear rapidly in abrasive environments. O-ring chains trap grease inside each link, dramatically extending lubrication intervals and wear life, but introduce a small amount of frictional drag. X-ring and Z-ring designs improve on O-ring geometry by reducing the contact area of the seal against the pin, cutting frictional losses while maintaining comparable lubrication retention — making them the preferred choice for performance street and track use where both longevity and efficiency matter.

Pitch sizing — typically expressed as 420, 428, 520, 525, or 530 — directly governs the chain's load capacity and weight. Smaller pitch chains (420, 428) are lighter and suit smaller-displacement, lower-torque applications such as motocross and lightweight sport bikes. Larger pitch chains (525, 530) carry significantly higher loads and are the correct choice for high-torque street bikes, drag bikes, and any application running substantially more power than stock. Running an undersized pitch chain on a high-torque application is one of the most common causes of premature chain failure and sprocket damage.

Link plate heat treatment and pin surface hardness define wear resistance under load. Chains using induction-hardened pins and chromoly link plates resist the micro-pitting and elongation that cause pitch stretch — the cumulative lengthening of a chain that eventually throws it off the sprockets or causes binding. High-end competition chains often combine hollow pins (to reduce weight) with surface treatments such as nickel plating or DLC coating that simultaneously improve hardness and corrosion resistance. When evaluating chain quality, ask specifically about pin material and surface treatment — this is where budget chains cut corners most aggressively.

Drive Chain Pitch Selection by Application and Power Level

Price Guide

Entry ($1.99–$180): Replacement-grade chains suitable for standard street use, light recreational riding, or low-budget builds where service intervals will be kept short. These are typically standard roller or basic O-ring designs in commodity steel — functional, but expect measurably shorter service life and faster sprocket wear compared to mid-range options. Correct for restoring a vehicle to operational status, not for building performance.

Mid-range ($180–$1,500): Where the majority of performance street, track-day, and serious off-road builds land. This tier covers quality X-ring and Z-ring sealed chains with hardened pins, precision-ground link plates, and consistent pitch tolerances — the specifications that translate to real-world durability and efficiency gains over OEM. You're also accessing full drivetrain component kits, clutch assemblies, and differential hardware at this price point, which is where most enthusiast builds are properly equipped.

Premium ($1,500–$4,999.99): Competition-spec complete systems — twin-disc clutch kits, air locker traction packages, full link kit assemblies, and billet drivetrain components engineered to survive sustained race use. These products are justified when the cost of a drivetrain failure exceeds the cost of the upgrade, or when the application demands components built to tighter tolerances and higher material standards than anything available in the mid-range tier. Not necessary for street or occasional track use, but the correct choice for anyone running competitive motorsport.

Who Is This For?

This category serves a broad spectrum of performance applications — from daily-driven street builds requiring durable OEM-replacement drivetrain components, all the way to purpose-built race vehicles where every drivetrain component must be engineered to competition tolerances.

Drag Racing — 8.1/10

Drag racing scores the highest in this category because drivetrain components face their most severe stress at the launch — peak torque multiplication through the drivetrain coincides with maximum shock loading on every chain, clutch, and axle component simultaneously. Chains and clutch assemblies in this application must handle instantaneous load spikes that dwarf steady-state running loads, making tensile strength rating and material quality non-negotiable. The 127 products in this use case cover the full spectrum from launch-optimized clutch kits to heavy-duty chains rated well beyond peak drivetrain output.

Racing Competition — 8.0/10

Sustained competition use demands components that maintain consistent performance across an entire race or event — not just for a single hard launch. Chain stretch, clutch fade, and differential fluid breakdown under sustained high-RPM cycling are the primary failure modes that competition-grade components are engineered to resist. At 8.0/10 across 170 products, this segment covers the widest range of genuine race-spec hardware in the category.

Track / Autocross — 7.8/10

Track day and autocross applications demand drivetrain components that can handle repeated high-load cycles with minimal recovery time between sessions. Unlike drag racing, the loading is sustained rather than instantaneous — thermal management of clutch and differential components becomes as important as raw strength. The 157 products in this use case include both the clutch hardware and differential components needed to keep drivetrain temperatures in check through back-to-back sessions.

Street Performance — 7.7/10

Street performance represents the single largest use case in the category by product count, with 192 products and a solid 7.7/10 score — reflecting that most performance enthusiasts need components that balance genuine performance capability with street-legal drivability and reasonable service intervals. The best street-performance drivetrain components in this category are those that improve power transfer efficiency and durability without the drivability trade-offs that come with pure race hardware.

Weekend Off-Roading — 7.7/10

Off-road use exposes drivetrain chains and components to the combination of shock loading, contamination, and extreme articulation angles that kill stock parts faster than almost any other application. At 7.7/10 across 82 products, the off-road segment includes heavy-duty prop shafts, differential lockers, and link kits specifically engineered to maintain drivetrain integrity through full suspension travel in terrain that would destroy street-spec components within hours.

BikeMaster and Renthal both occupy the high-value performance street tier, with BikeMaster's 284 products averaging $66.03 and Renthal's 270 products averaging $80.53 — both brands delivering O-ring and X-ring chain quality that outperforms OEM at competitive price points. ProTaper rounds out the motocross and off-road segment with 242 products averaging $63.53, focused specifically on the lightweight, high-strength chain and sprocket combinations that off-road competition demands. For complete drivetrain system components — clutches, differentials, and associated hardware — ACT, Exedy, Clutch Masters, and Competition Clutch collectively offer over 1,000 products covering every performance tier, with each brand differentiating through specific friction material technology, pressure plate design, and torque capacity ratings validated in real competition environments.

Frequently Asked Questions

Are ACT clutches difficult to drive on the street?

It depends entirely on which ACT product line you're running. ACT's street and performance street clutch assemblies use organic or hybrid friction materials with clamp loads that are noticeably firmer than OEM but remain manageable for daily driving — pedal effort increases proportionally with clamp load, so a modest performance upgrade is drivable while a full-race twin-disc kit is explicitly not intended for street use. The key variable is pressure plate clamp load: higher clamp loads mean higher pedal effort, period. If you're running a built motor with a race clutch, expect a significantly heavier pedal and a shorter, more aggressive engagement window. Match the clutch specification to your actual use case — a street performance clutch on a modified daily driver is a practical choice, while a competition-only twin-disc kit on a street car will be fatiguing and wear faster than intended from the constant engagement cycling of normal traffic driving.

Are aftermarket brake discs actually worth the upgrade over OEM?

For performance street and track applications, yes — with the caveat that the improvement is application-dependent. Aftermarket slotted rotors improve pad bite consistency and outgassing clearance under repeated hard stops, while slotted and drilled combinations reduce unsprung weight and improve heat dissipation at the cost of slightly reduced rotor longevity. For pure daily driving on a stock-power vehicle, quality OEM-replacement rotors perform identically to OEM at a fraction of the cost of performance upgrades. The genuine benefit of performance rotors materializes under thermal load — repeated high-speed stops that raise rotor temperatures well above the range of normal street use — which is why track-day drivers and autocross competitors see measurable improvement while commuters do not.

Are aftermarket differential covers worth buying?

For any vehicle used for towing, off-roading, or performance driving, an aftermarket differential cover is one of the highest-value upgrades in the drivetrain category. The primary benefit is increased fluid capacity, which directly lowers steady-state operating temperature — differential fluid degradation is temperature-driven, and running cooler fluid extends both fluid service intervals and ring-and-pinion longevity. Secondary benefits include improved impact resistance from cast or fabricated steel construction versus the thin stamped steel of OEM covers, and in some designs, integrated drain plugs that eliminate the messy fluid dump required when servicing OEM axles. Magnetic drain plugs included in many aftermarket covers also capture ferrous wear particles, giving you a real-time indicator of differential health at every service interval.

Are aftermarket master cylinders better than OEM for clutch applications?

When running an upgraded clutch with a higher clamp load than OEM, an aftermarket master cylinder is often a functional requirement rather than an optional upgrade — the OEM cylinder bore is sized for OEM clutch actuation force, and it will generate insufficient hydraulic pressure to properly and consistently actuate a high-clamp-force aftermarket assembly. Larger bore aftermarket master cylinders generate proportionally higher system pressure, ensuring full clutch release at normal pedal travel without requiring excessive pedal force. Additionally, aftermarket units typically use higher-quality seals and anodized bore surfaces that resist fluid absorption and contamination better than budget OEM-equivalent units. If your clutch pedal feels vague, inconsistent, or requires excessive force after a clutch upgrade, the master cylinder is the first place to investigate before assuming the clutch itself is the issue.

Are air lockers more reliable than electronic lockers for off-road use?

ARB-style air lockers have a decades-long track record of field reliability in genuinely severe off-road conditions and are generally considered the benchmark for locking differential durability. The pneumatic engagement mechanism relies on a compressed air source — typically a small onboard compressor — and a simple air solenoid; there are very few electrical components inside the differential itself, which means the internals are resistant to water ingestion, mud packing, and the vibration that can fatigue electrical actuator components in e-locker designs over time. E-lockers offer the advantage of not requiring an air compressor and can engage faster in some designs, but their internal electric motors and wiring connectors represent additional failure points in harsh environments. For expedition-level off-road use where reliability in remote conditions is paramount, air lockers remain the preferred professional choice; for moderate weekend off-roading where convenience matters more than ultimate durability, quality e-locker designs are entirely adequate.
