LLY-LBZ 66mm Billet Turbo Wheel and Cover Kit

For the LLY and LBZ 2004.5-2007 Classic Duramax we now offer a 66mm wheel and cover kit for the factory turbo. Drop in billet wheels don't gain much power. Results are found in increasing the bore size along with improving wheel design. With larger injectors and CP3 you can expect to reach power in the 675-700hp range. Kit comes with our billet 66mm 6X6 blade compressor wheel, Machined compressor housing, machined backing plate, Oring and loctite. No core charge.

Will Not Fit LMM or LML trucks.
