Kiggly Main Girdle - 6-Bolt 4g63

For 4G63 and G4CS blocks, the 6-Bolt Main Girdle is essential in builds above 350hp. It requires minor engine block grinding at the lower two rear main cover bolts and the use of main studs (ARP is a commonly used brand). This girdle stiffens the main caps and greatly reduces main cap to block flex and fretting. It is highly recommended to line hone the engine with the girdle installed.
