Hummer H3T Camshafts - COMP Cams XFI 222/234 Hydraulic Roller Cam (2009). A proven street/strip grind that adds strong mid- to high-RPM power to properly prepared 5.3L H3T builds and other GM LS applications.

Built for GM GEN IV LS engines configured without VVT or AFM, this hydraulic roller profile balances drivability with serious top-end pull. It’s a popular choice for 5.3L, 6.0L, and 6.2L projects across platforms including Hummer H3/H3T, Camaro, Corvette, CTS/CTS-V, Silverado/Sierra, and Pontiac G8. Proper engine setup and calibration are required; a programmer/tune is a must.
