Our billet aluminum rear big block Mopar seal cap is fully CNC machined from a solid block of 6061 T-6. We make them slightly wider than the original factory units so there’s no slop when it fits up into the block, which helps to avoid leaks. Don’t forget the special countersunk bolts OR gaskets/seals below! Fits all B/RB Big Block Mopars!
TORQUE SPEC: 30 ft-lbs
