More RPM, Less Valve Float

Valvetrain stability is critical when building a GM LS7 or LT that regularly sees high RPMs. COMP Cams 1.900-Inch Street Performance Beehive Valve Springs are made of premium ovate wire that’s heat treated to guarantee spring rates, then multi-peened and polished to improve fatigue resistance and reliability. The beehive design reduces valvetrain mass to keep harmonics and vibrations under control at high RPMs on engines equipped with camshafts up to .650-inch valve lift.

Street Tough. Strip Ready.

When you modify your car to make more power, you need a transmission that can keep up. TCI StreetFighter Transmissions provide race-inspired performance without sacrificing street manners. They feature upgraded clutches, bands, sprags, and roller clutches to handle abuse, plus increased line pressure and performance-calibrated valve bodies for firm, positive shifts. Most models offer the ability to bang through the gears yourself or let the transmission shift automatically. TCI StreetFighter Transmissions are available for most popular GM, Ford, and Chrysler applications.
