S&S Diesel Motorsport Releases 50 State LML CP3 Conversion Kit

Our friends over at S&S Diesel Motorsport has recognized the issues with the LML Duramax engine including the Cp4.2 high-pressure injection pumps failures you’ve probably heard about. The S&S solution is to remove the problem before it becomes a bigger problem by replacing the CP4.2 with a tried and true, bulletproof CP3 high-pressure fuel pump.

CP4 high-pressure pumps are the obvious weakness of these LML Duramax engines. They have a high failure rate and with that, they typically take out the entire high-pressure system with it. That includes fuel injectors, rails, and the lines which are very expensive. S&S offers the only CARB-compliant 50-state CP3 conversion kit available for the LML trucks. This kit includes all of the necessary hardware to replace that troublesome Cp4 and requires no tuning changes to swap.

What you see is what you get. Your new CP3 injection pump, the fuel lines, and the hardware.

Having a kit that can swap you from a known issue to a known working unit is one thing. To have a kit of this importance and comply with the CARB guidelines is a feat in itself. CARB guidelines are very strict in this day in age so props to the crew at S&S for getting this done.

S&S’s kit maintains factory emissions control equipment and comes at a MAP price of $2,500. They also offer two other versions of the LML CP3 conversion kits from competition trucks which do not require after-treatment. One tuning required version for $1,780.00 MAP, and one drop-in, no tuning required for $2,075.00.
