Fits Triumph TR2, TR3 and TR4

Sold as a complete assembly

Description

Complete assembly ready to bolt on. Available in 1.55 or 1.65 rocker ratio and 1.53 inch or 1.61 inch rocker shaft height.

1.53 inch shaft height is the same as original for replacement of the original rocker assembly without changing push rod length.

1.61 inch shaft height provides better roller to valve stem geometry but may require longer push rods.

For information about the benefits of increased ratio roller rockers read our Roller Rocker Benefits page found in the Info Pages section, or click the link HERE.

 

Installation Notes:

Installation of high ratio rockers will increase your net valve lift. Check your valve spring capacity before installation. For best cam life, keep valve spring pressures as low as possible but strong enough to avoid valve float.

Using 1.65:1 ratio rockers with 3/8″ diameter push rods may cause interference between the push rod and the push rod tube in the head.

Good Parts TR2-4 rocker assemblies do not fit under the original rocker cover. An after-market aluminum rocker cover or a Rocker Cover Spacer (SKU 33) is required. Using an original rocker cover without a spacer will cause interference issues.
