Oil Restrictor Kits

Racing engines equipped with roller rocker arms should have the flow of oil to the lifters restricted. This forces more oil to the engine bearings where it’s needed, and cuts horsepower losses caused by oil windage.

B&B offers two styles of Restrictor Kits for reducing the volume of oil that is pumped to the engine’s top end. Number 48000 (pictured) is a pair of precisely drilled aluminum restrictors which simply replace the oil galley plugs at the rear of the block. Two extra o-ring seals are included.
