LML CP3 conversion kit w/pump Tuning Required

LML CP3 conversion kit w/pump – Competition Use Only – Tuning Required

S and S Diesel Motorsport, the world leader in common-rail diesel injection, has developed a solution for CP4.2 high-pressure pump failures that have plagued the LML Duramax engine. The S and S solution is to remove the problem before it becomes a problem by replacing the CP4.2 with a tried and true, bulletproof CP3 high-pressure fuel pump.

CP4 high-pressure pumps are the Achilles heel of the LML Duramax engine because of high failure rates and commonly taking out the entire, very costly, high-pressure system with it (injectors, rails, lines). S and S Diesel Motorsport offers the first CARB-compliant (EO #D-756) 50 State CP3 conversion available for the LML.  This includes all hardware necessary to replace the troublesome CP4 with a bulletproof CP3, requires no tuning changes, and still maintains factory emissions control equipment for $2,600 MAP.

S and S also offers two other versions of LML CP3 conversion kits for competition applications that don’t require after-treatment. One tuning-required version for $1,780.00 MAP, and one drop-in no tuning required for $2,175.00 MAP.
