Shop Builds Chevrolet Suburban SUVs With Diesel V8 For Serious Towing
Duramax Specialties Company takes 2003-2013 Chevrolet Suburban and GMC Yukon XL and diesel engine them to make large SUVs capable of even better towing platforms. The job goes far beyond just replacing the engine, however. After the conversion, you would think it is something that comes straight from the factory.
The company uses the LBZ, LMM, and LML versions of Duramax diesel engines and hooks up to an Allison six-speed automatic transmission. Duramax Specialties combines them with GM factory components for parts such as the water pump, belts, coolant bottle and many more. There are also upgrades such as an MBRP Inc downpipe, a four-inch Flo-Pro aluminum exhaust, and a modified driveshaft with new U-joints.
The suspension is also getting some attention. The company adapts parts such as new lower ball joints, tie rods and Bilstein shocks,
During the conversion, the Duramax Specialties refreshes the SUV’s frame by putting it in an acid bath and repainting it with POR-15 to prevent rusting.
Customers can also further customize the look of the SUV. For example, it’s possible to swap out the nose of the contemporary rugged pickup or even do something like put a Yukon Denali front end on a Suburban.
If anyone already owns one of these SUVs, they can send it to Duramax Specialties for an upgrade. The company also sells turnkey examples that start at $ 31,900 for a 2003-2006 Suburban with the LBZ Duramax.
For the 2021 model year, the new generation of Suburban and Yukon is again available with a diesel engine. The 3.0-liter inline-six produces 277 horsepower (207 kilowatts) and 460 pound-feet (623 Newton-meters) of torque. It connects to a 10-speed automatic transmission. Fuel economy for this configuration is not yet available.
