The XP-Series main bearings are narrowed for large radii crankshafts and feature enlarged, chamfered oil holes with full, 3/4 in., or 1/2 in. grooving for improved oiling. They deliver consistent and reliable performance with a high-load capacity. These race-only Xtreme Performance (XP-Series) Tri-Lecular main bearings are proven track-tough to handle the ground-shaking power of your race engine.

Dinan Underdrive Pulley Kits

Dinan underdrive pulley kits are designed to increase power by reducing the parasitic drag on your engine from spinning the alternator, water pump, and AC compressor. They accomplish this by slowing down the speed of these accessory drives that rob your engine's power. Dinan has done extensive hot-weather testing, so you can be assured that your engine is safe. The Dinan underdrive pulley is made of aircraft-quality 6061 alloy, anodized black, and engraved. Plus, they do not modify your harmonic damper as some underdrive pulley kits do, which can be harmful to your engine.
