This is a complete set of 16 GM LS-series pedestal-mount rocker arms with Brian Tooley Racing's premium TK002 trunnion kit already installed at the factory. Each rocker is a full-roller, OEM-style design finished in steel/natural. The TK002 trunnion is BTR's V2 design, with a pre-installed inner race pressed from 52100 heat-treated bearing steel (an upgrade over the 8620 carburized steel used in TK001/OEM trunnions) and a self-oiling axle that priority-feeds oil to the trunnion. Rocker mounting bolts are not included and must be ordered separately.

FAQ
Are the trunnions already installed on these rocker arms?
Yes. Each of the 16 rocker arms in this set comes with BTR's premium TK002 trunnion kit pre-installed, so there is no separate trunnion assembly required.
Do these rocker arms include mounting bolts?
No. This set does not include rocker arm bolts; they must be purchased separately to complete the installation.
What is the difference between TK001 and TK002 trunnions?
TK002 is Brian Tooley Racing's premium trunnion kit, offered as an upgrade over the standard TK001 trunnion kit.
Is there a valve cover clearance issue to be aware of?
Yes. BTR notes the TK002 trunnion can contact the passenger-side valve cover baffle on early-style LS1/LS6 valve covers.
