Performance
& competition.
For higher-output trucks, dedicated competition vehicles, and trucks that arrive already modified. M&R Diesel Performance starts with the actual mechanical combination and builds from there.

The whole combination

Existing hardware, current power, event use, response goal, engine support, transmission capacity, cooling, and driveline all affect the plan.
Compound systems

Already modified?
Bring us the truck you actually have.
Modified trucks are not excluded from turbo, fuel-system, engine, transmission, driveline, cooling, diagnostic, or general performance work. Their existing configuration becomes part of the compatibility review.
Marking a truck modified or competition-use does not automatically publish or recommend a restricted product class. The public store still contains only products manually approved for its sanitized U.S. storefront view.
