Product Description

This Roller Lifter Anti Rotation System allows you to use our affordable Sealed Power Hyd Roller Lifters in your Pontiac. The system uses "Dogbones" to prevent the lifters from rotating and a "Spider" to hold the Dogbones in place.

You will need to cut the Spider in two and adjust the sprung steel "legs" but you will save a bunch of money and enjoy a very quiet valvetrain.

On 1967-1969 blocks you may need to clearance the dogbones or the block for the ribs in the lifter valley. 1970 and later blocks do not have this clearance issue.
