Reinforce Your 4A-GE Bottom End

The 4A-GE engine is a legendary platform, but when building for increased power, the bottom end needs extra support. The ARP Main Bolt Kit is designed specifically for 4A-GE applications, providing the necessary strength to keep your main caps securely fastened under high-load conditions. This kit is essential for anyone rebuilding their engine for track use or spirited driving.

Key Features for 4A-GE Builders
