LS1 Pressure Plate Bolt Kit

The ARP LS1 Pressure Plate Bolt Kit (Part Number 134-2201) is an essential fastener upgrade for any serious LS engine builder or enthusiast tackling clutch assembly work. Whether you're assembling a stock LS1, upgrading to a higher-clamp-load pressure plate, or rebuilding after clutch failure, this bolt kit ensures critical pressure plate-to-flywheel connection integrity. ARP bolts are the industry standard because they deliver consistent preload and eliminate the risk of fastener failure under the extreme cyclic stress of engine operation and aggressive driving.

This pressure plate bolt kit features premium-grade fasteners engineered to LS1 specifications, delivering superior tensile strength and repeatability compared to OEM hardware. ARP bolts undergo rigorous quality control and are precisely engineered to maintain consistent clamping force across all fastening points, which is critical for balanced pressure plate operation and reliable power transmission. The kit's design accommodates the specific bolt pattern and thread geometry of LS1 pressure plates, ensuring proper fit and optimal load distribution during installation and under full-throttle demand.

Mechanics and engine builders trust the ARP LS1 Pressure Plate Bolt Kit for both street and competition applications, from mild-mannered daily drivers to race-prepped vehicles pushing 400+ horsepower. Installation pairs seamlessly with Chevrolet LS1 engines across all model years, as well as LS variants used in platform swaps and custom builds. Use this kit whenever replacing a pressure plate, performing clutch service, or rebuilding an engine assembly—proper fastener quality directly impacts drivability, longevity, and safety of your drivetrain investment.
