PROJECT LOOKS. MUSCLE. LONGEVITY

IMPROVING A 2012 LML DURAMAX
While the 2011-’16 Duramax has a decent-sized transmission cooler stuffed behind the bumper, in heavy towing situations in the heat of the summer, there is an advantage to a larger cooler with increased surface area and better placement for increased airflow across the core. The new Mishimoto trans cooler was designed to be the answer to every Allison’s excessive heating problems.

After a few months hiatus, Project LML is back for its final installment of the build. Over the last year and a half, this 2012 Silverado made quite the transformation, with everything from suspension and chassis improvements to horsepower upgrades under the hood. When the project was introduced in the March 2018 issue of Diesel World, the plan was to take a completely stock, highermileage LML Duramax and turn it into the ultimate daily driver with the versatility to tow whatever you needed, drive where ever you wanted, and do it all with unmatched performance and reliability.

This month, it was time to focus on a few upgrades that had been skipped through the build but are still items any GM owner should contemplate when perfecting the longevity and overall reliability of a truck. Early on in the build we installed a Stage 3 leveling kit system from Kryptonite Products that included upper control arms, leveling keys, ball joints, and new Bilstein shocks. While all of that helped raise the truck up and kept proper CV angles and ball joint angles, we overlooked some key steering upgrades. With the addition of some heavier wheels and tires, we added some strain on the front end and knew the factory tie rods wouldn’t appreciate it if we ever had to use the four-wheel drive system. The GM independent front suspension has been notorious for bending or breaking tie rods in off-road situations or in sled pull/drag race competitions that require planting a bunch of power through the front tires. To prevent an issue that might leave us looking for a tow, the stock tie rods were replaced with the massive Kryptonite Death Grip Tie Rod package. The Death Grip tie rods use chromoly nickel heat-treated outer studs and steel inner-ball sockets for unmatched durability. The massive hexagon-shaped bodies are super strong and make it easy to install and adjust for proper alignment. Kryptonite also prides themselves with their USA-made products and lifetime warranty, meaning these will be the last set of tie rods you ever buy.
