Arrington Performance Billet Engine Main Cap Set 

These new engine main caps are a perfect solution for your high performance 5.7L, 6.1L or 6.4L HEMI engine build. Upgrading your main caps will prevent unwanted main cap walk at high RPMs, making them a must for any high horsepower supercharged Mopar application. Without strong main caps, like this set, metal transfer and friction may occur between the cap and block at the center of the bearings. Weak main caps with cap walk can cause problems ranging from bearing oil clearance problems to complete engine failure. Insist on the best caps on the market- Arrington Engine main caps and prevent HEMI engine cap walk before it starts. Each cap features an engraved Arrington Engines Logo and a directional arrow to ensure proper orientation. For convenience, each cap is numbered and has a threaded bolt hole for easy removal. Because each block is unique, each cap must be machined by a qualified engine shop.

Update: These caps are now pre-bored. Only hone is required unless engine block exceeds factory tolerances.
