PRODUCT DESCRIPTION
Name: ARP 203-6301 Toyota 1.8L 2ZZGE DOHC Connecting Rod Bolts
Brand: ARP
Part Number: ARP-203-6301
Country of Manufacture: United States
Since factory connecting rods (or aftermarket versions of OEM rods) are used in a variety of applications, from rebuilt stock engines to modified engines for oval track, marine, and
drag racing, including those with superchargers and/or nitrous injection systems, ARP offers replacement connecting rod bolts in three different models. All of them are substantially better
than stock OEM bolts and most aftermarket bolts. Without a doubt, the most important fasteners in any
engine are the connecting rod bolts, as they are critical to the proper functioning of the entire rotating assembly. A broken bolt will lead to catastrophic engine failure.
ARP bolt features:
- ARP connecting rods forged from the highest quality materials.
- Heat-treated using special vertical racks to ensure full 360° penetration.
- Threads rolled after heat treatment for up to 10 times greater fatigue strength.
- Precision CNC machined to rigorous specifications.
- Specially designed for optimal reliability in every application.
ARP connecting rod bolts are used in a wide range of applications, from exotic 18,000 rpm Formula 1 engines to 10,000 horsepower Top Fuel engines using nitromethane.
