Inside every piston engine, the connecting rods link the pistons to the crankshaft. Rod bolts keep the big end of each rod fastened around its crank journal. These bolts are stretched and released over and over every time the engine runs, so they matter a great deal to reliability. Builders often replace them during a rebuild, or when adding boost, raising the rev limit or otherwise asking more of an engine. A kit groups the bolts for the job into one purchase.
This page sits at Engine Components › Rod Bolt Kit. We currently have 13 kits in stock, all from ARP, a name many engine builders know well. Examples include the ARP Porsche M10 Rod Bolt Kit and the ARP Volkswagen / Audi / FSI / TFSI M9 Rod Bolt Kit.
Confirm the kit is listed for your exact engine, not just the vehicle model.
Ask whether your rods need machining or resizing when you change fasteners.
Follow the bolt maker's instructions for lubricant and tightening method, since correct preload is critical.
Have a qualified machine shop check your rods if you are unsure.
To narrow the list, pick your vehicle to see what fits.
