MACE ALLOY MAIN GIRDLE TO SUIT HSV GRANGE WH WK WL WM WN LS1 LS2 LS3 5.7L 6.0L 6.2L V8This main cap girdle is designed to reduce "cap walk", stop block web flexing and eliminate cracking of the main caps block webs; this is achieved by boxing in the main caps. Our light weight girdle evenly distributes load and dampens harmonics by bolting the main cap studs together to create a super strong rectangular cage.

This main cap girdle is designed to reduce "cap walk", stop block web flexing and eliminate cracking of the main caps/block webs; this is achieved by boxing in the main caps. Our light weight girdle evenly distributes load and dampens harmonics by bolting the main cap studs together to create a super strong rectangular cage. The brace nearly doubles the main web support area in the engine.

In addition, due to the close proximity of the main stud girdle to the crankshaft and rods it also aids in stripping oil off of the crank, which in itself yields a net gain in HP.

Fabricated from 12.5mm thick 6061-T6 aluminium, these girdles are a must for high rpm/high horsepower applications where block rigidity is critical.

IT WORKED!
I tried 4 bottles of two other products. They did not work. One bottle of Moly (in 1/2 tank of gas) fixed the problem after driving 100 miles. GREAT PRODUCT!
