The center main bearing cap is barely adequate for a stock engine due to the flexibility and whip of the Mini's crank. For performance engines it is common to add an additional steel strap to help support the cap and prevent the bolts from splaying outward. Other strap kits require that you have a machine shop thin down your center main cap first. Our Fortech-designed strap cradles the center main cap of all solid-back (no tappet covers) 1275/1300 A Series and A+ blocks without further modification. CNC machined from high-carbon billet steel. Kit includes high tensile strength ARP bolts and hardened parallel-ground washers for precise fit.
