This Combo Deal consists of ACL Race Main Bearings and ARP Main Studs for SR20DET. This is what you need to reinforce the crank, ensure reliability, and prepare for track/racing use. This combo comes with ACL Race Main Studs in standard size.
ACL Race Main Bearings:
ACL race main bearings are manufactured with a tri-layer metal in order to withstand high RPM conditions, high stress loads, and high temperatures. Each ACL race bearing design features the following:
- Large chamfer to accomodate larger crankshaft fillets
- 3/4 groove main bearings to optimize bearing load carrying capacity and oil flow to rod bearings
- Incresed crush and tighter wall tolerance for better seating
- Improved overlay and reduced thickness for increased fatigue strength
- Hardened steel backing to maintain crush under high loads and temperatures
ARP Main Studs:
- Replace your stock main studs with ARP heavy duty main studs. These main studs offers superior clamping force under high boost applications. A good upgrade when doing an engine rebuild or building a race motor. This kit comes with studs, nuts, and lube.
