Strange Engineering is proud to introduce its line of billet aluminum main caps to accommodate Ford 8.8 , GM 10 bolt, GM 12 bolt rear ends and Dana 60 rear ends. As horsepower increases, the factory caps will deflect which lead to premature wear of the gear and bearings and will ultimately result in failure. The Strange Engineering billet caps are made from 2024-T351 aluminum and provide increased rigidity and strength when compared to the factory cast main caps. The reduced deflection improves gear life, bearing life and the overall strength of the OEM housing. Each pair of caps is supplied with main cap bolts and detailed instructions for machining.

H1120 – GM 8.5” 10 bolt caps

H1121 – GM 12 bolt caps

H1122 – Dana 60 caps

H1124 – Ford 8.8” caps

All caps are $88.00 per pair.
