Triumph Roller Rocker Assemblies

These roller rockers will increase power while reducing friction and wear because they use needle bearings in the roller as well as in the rockers pivot to ride on. What’s more, the ratio of the rockers are increased to open the valve further than the original units 1.45:1 ratio. These rockers come in two ratios, 1.55:1 and 1.65:1, and are sold in sets with a specially designed rocker shaft to insure perfect operation. Stock towers are retained.  Check the coil bind limit on your current valve springs before installing these parts.

Please read our purchase policy.
