4 Bolt Splayed - Center Main Cap Kit

Our four-bolt main cap is engineered for High Performance and Blower applications for 200+ horsepower.  Existing "heavy duty" center main cap and cap reinforcing "strap systems" add undue stress to the center main web, which is already the weak link.  Our cap overcomes this by using a true splayed (36 degree) design, which distributes a percentage of the load to the outboard pan rail.  This, in turn stiffens the center webbing, increasing the torsional rigidity by as much as 75%
