Rated 4.9 out of 5 stars.
Upgrade your LS engine's valvetrain with this set of 16 rocker arms from Brian Tooley Racing.
These are the RKR-LS-1.7E model, made from machined steel right here in the USA.
They're designed for the popular LS engine family, including 4.8L, 5.3L, 5.7L, and 6.0L motors (LS1, LS2, etc.).
Note that these are the rocker bodies only—they don't include bearings, so you can use your own preferred trunnion upgrade.
A solid performance part for any LS build.
Get reliable, high-rpm performance from a trusted name.
