    Brian Tooley Racing BTR TK002NB Features:

    FOR LS1/LS3/99-13 LS TRUCK STYLE ROCKERS The all new V2 Trunnion Kit builds on the success and knowledge we gained with our V1 kit. The V2 features a Trunnion with pre-installed inner race bearings. The V1 kits have stood up to an enormous amount of abuse, but we decided to upgrade them to a pressed inner race comprised of 52100 Heat Treated Bearing Steel, over the more commonly used 8620 Carburized Steel found in our V1 kits and many OEM applications. Additionally, these feature a self oiling axle with priority feeding to the Trunnion itself

    Boost Your LS Engine with Rocker Arms from Brian Tooley Racing

    Upgrade your valvetrain's strength and precision with Brian Tooley Racing (BTR) Engine Rocker Arms and Trunnion Kits—built for improving durability and superior RPM capability. Reinforced with redesigned top rails and oiling ports, delivers up to more strength compared to OEM rockers, supporting higher valve lift and better tip wear resistance. They’re available either as bare arms or fully assembled sets with BTR’s hardened trunnion bearings, eliminating failure‑prone factory bushings.
