Pro Series Flywheel Bolt Kit 7/16"-20 x 1.00

The ARP 200-2807 flywheel bolt kit provides a significant upgrade over OEM hardware, designed for both race and street applications where performance and safety are paramount. These Pro Series bolts are forged from aerospace alloy and undergo a heat-treatment process before thread rolling and machining, contributing to their exceptional strength. Key features include an exclusive, flat 12-point head design that offers increased strength and an improved flywheel register due to a larger-than-stock shank diameter. With a rating of 200,000 psi, these bolts are built to withstand demanding conditions. The kit includes six bolts, each with a 7/16"-20 thread size and a 1.00" underhead length, finished in a black oxide coating. This kit is specifically designed to fit Small Block Chevy Gen 1/2 engines from 1987 and newer that feature a 1-piece rear main seal, as well as Big Block Chevy engines from 1990 and newer with a 1-piece rear main seal. This precise fitment ensures optimal performance and reliability for compatible GM V6 and V8 applications.
