Socal 04.5-10 Duramax Billet Injector Clamp Kit

SoCal Diesel pioneered the Duramax LLY-LBZ-LMM billet injector clamp kit in 2011.

We thought we could solve the injector movement issue with a better bolt. Or actually a new stud and nut arrangement that would apply more clamping force without increasing the stress to the threads of the aluminum head. We found that increasing the clamp load with the newly designed stud and nut only served to distort and bend the factory injector clamp.

Once again we were surprised at the factory's choice of alloy. They chose an alloy that had the tensile strength of the hardened bubble gum you found underneath your chair in school as a kid. While perfectly ok for stock power levels, it certainly wasn't up to the task of 4 times the cylinder pressure and power of a stock LLY-LBZ-LMM.

After a little CAD work, a little CAM work, and after a quick trip to the heat treater's facility, we had the first set of LLY-LBZ-LMM billet injector clamps.

SoCal Diesel's billet injector clamp kit significantly increases the clamp load on the injector, preventing the injector and the injector cup from becoming unseated when subjected to extreme power levels. This kit is a must for any high horsepower build! Over the years this kit has seen in excess of 1700 RWHP.

The kit includes 8 billet clamps, 8 studs and 8 nuts.

Don't be fooled by other companies who think R&D stands for Rob and Duplicate. Get the kit designed and manufactured by the innovators at SoCal Diesel not the imitators somewhere else.
