Mash Motors specializes in Duramax Diesel Conversions for the Hummer H1 and H2 and large SUV’s including the Chevy Suburban, Yukon, and Avalanche. We are also the first company to successfully convert the Hummer H3 with the Vortec 6.0 liter engine and 4L60HD transmission by GM.
We also provide the latest in aftermarket performance parts and accessories to complete your conversion. We can supply your vehicle with any part you have seen, or create a one-of-a-kind look to customize your vehicle using our partner, Absolute Dimensions, a full-line machine shop, also located in Wichita, Kansas. We send nothing out to an unknown supplier in hopes that it returns in the condition we expect. Instead, we oversee all products that are machined or manufactured to ensure an exact fit and sleek look for your vehicle.
