What Owners Say
Owners and enthusiasts consistently praise ARP main bolt kits for their superior quality and smaller head design that simplifies installation in tight engine bays. Many report these bolts handle serious power—well beyond 700hp—with some noting GM even uses similar hardware in their 750hp LSX crate motors. Machinists appreciate how much easier and faster ARP hardware is to work with compared to OEM bolts, and builders value that they don't require torque-to-yield specifications or confusing torque angle gauges. The honest caveat: most builders recommend line honing when switching from OEM to ARP hardware, as the different clamping forces can affect main bore roundness. Despite this additional machining step, ARP maintains its reputation as the professional's choice for serious engine builds.
