Product Description
The 7.3 main caps lack the strength to provide the stability needed at very high power levels. These billet main caps offer the strength needed at BIG power, are compatible with the available main studs and side bolts, and only require line honing for use. No additional block machining required.
When combined with the OptiTorque main studs and side bolts they'll provide the strength and stability needed for most applications. In fact, they'll hold up to more than the block can handle.
