Product Details

ARP is well-known for making strong fasteners, and this main bolt kit for the Rover 4.0L and 4.6L V8 engines is no exception. When you're rebuilding or upgrading the bottom end of your engine, the main bearing caps are critical. They hold the crankshaft in place, and the bolts that secure them need to be up to the task of handling the stresses of combustion and rotation.

This kit uses ARP's 8740 chromoly steel bolts, which are heat-treated to a high tensile strength. They are designed to be a direct replacement for your stock main bolts, but with a significant improvement in strength and clamping force. This helps ensure the main caps stay securely in place, even under demanding conditions, which is important for the longevity of your engine build. The bolts are also centerless ground for a precise diameter, which helps them seat properly in the block.

When you're working on the core of your engine, using reliable components is key. This kit is a solid option for anyone looking to ensure the integrity of their Rover V8's bottom end.
