S&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&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&S Diesel Motorsport offers the first CARB-compliant (EO D-756-4) 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&S also offers two other versions of LML CP3 conversion kits for competition applications which 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.

Favorite ball!
My dog absolutely loves this ball. I have a 11 pound mini golden doodle for reference. It is super durable and easy to clean. It is easy for her to get her teeth around and is one thing she has not chewed up.

Sturdy and long lasting.
These balls are a favorite of my Sheltie! She loves to chase after them and catch them in the air. My dog is not a chewer so I can't say how they hold up under aggressive circumstances! They do last a long time .

Very versatile and durable dog toy
This is not a good toy to leave wit big dogs unattended. That being said it is a GREAT dog toy for households that have a variety size of dogs. Our Golden Retriever and 6 pound Pomeranian both play with it. Both retrieve it and occasionally share carrying it back to us. I know it will eventually get destroyed but that is what dog toys are for. Very durable and with the holes, it allows small dogs to pick it up as easily as larger dogs.
