I put a new L9H motor in my 2009 Hummer H2 with a Magnuson Supercharger, installed a re-man'd 6L80e & transfer case, installed all Kryptonite front end suspension, new cross-drilled & slotted rotors, 4.88 gears, new front axels from RCV in Pennsylvania, re-balanced the driveshafts
and everything else new too as far as led lights, black door handles, new engine parts that are high performance, tuned it all up and it runs great now...527hp at 5355 rpm with 558 ft.lb.
torque...with 37x13.50x22 Nitto Recon Grapplers & Power-Amp retractable running boards. It's my daily driver and is a beast. I just got to hyperdip the chrome gas cap and back of side view mirrors black.
