SBC Shaft Rocker System w/Brodix 18c/18 Clone

T&D Machine Products offers shaft mount roller rockers made from extruded 2024 aluminum. They are CNC-machined with intricate oil galleries to direct oil to the shaft bearings and roller tip. Adjuster screws are 7/16" and broached for a 3/16" socket. Deep, case-hardened 8620 steel shafts are tempered for strength. Optional .040" spring oiler holes spray directly onto valve springs for extended spring life. T&D SportComp Shaft Roller Rockers reduce valve train weight and valve lash adjustments, increasing RPM potential. The system eliminates stud girdles and provides better head bolt accessibility. Sets of 16 include all installation hardware.
