The 2020 L5P Duramax received quite a few major upgrades, as well as a huge facelift. The truck looks heavy and powerful; the powerful look is backed up by 445 horsepower and 910 pounds of torque. That power is well distributed throughout the RPM range by the Allison ten-speed transmission. With ten gears, the 2020 L5P Duramax performs much better in overcoming obstacles and towing heavy loads. The fuel economy also benefits greatly! However, the 2020 L5P Duramax would be better with a few upgrades to the engine and the suspension from the aftermarket. At HeavyWeight Diesel we hand-pick the best engine, suspension, and transmission parts on the market so that our customers can have the highest quality mods.
HeavyWeight Diesel also stocks lift-kits and purely visual modifications. If you're dissatisfied with the ride height or the look of your truck, we'll help you get exactly what you want out of your L5P Duramax!
Pushing an already powerful truck to its maximum requires effort and knowledge. Contact HeavyWeight Diesel staff if you need advice, and we'll point you in the right direction!
