Rocker Arms w/TK002 Trunnions Installed (16)

The Rocker Arms w/TK002 Trunnions Installed (16) from Brian Tooley Racing represents a precision-engineered valve train component designed for high-performance and racing applications where reliability under sustained load is non-negotiable. These pre-assembled rocker arms arrive with TK002 trunnions already installed, eliminating critical assembly steps and reducing the risk of improper fitment in the field. Built for serious enthusiasts and professional engine builders, this 16-piece set addresses the growing demand for drop-in valve train solutions that maintain factory-level consistency while supporting elevated RPM and boost conditions.

Each rocker arm in this set features precision-machined geometry optimized for load distribution and minimal deflection under sustained valve actuation. The TK002 trunnion design provides superior support geometry compared to earlier standards, reducing wear on rocker arm tips and extending the service life of both the arms and their mating valve stems. The factory-installed configuration ensures alignment tolerances remain within specification, eliminating the guesswork associated with field assembly. Weighing 6.44 pounds for the complete set, these components are engineered from material specifications chosen to withstand the cyclic loading encountered in modified and forced-induction engines.

Professional engine builders, race teams, and serious performance enthusiasts benefit most from this ready-to-install rocker arm set when rebuilding or upgrading valve train assemblies on small-block applications. Installation requires familiarity with OEM cylinder head specifications and proper torque sequencing—this is not a beginner modification and demands respect for clearance specifications and rocker geometry. Verify compatibility with your specific engine platform and head casting number before ordering, as rocker arm applications vary significantly across engine families. This is a critical precision component where fitment directly affects engine reliability and performance consistency.
