2002 Chevrolet Silverado 2500HD Duramax Project Update

A Look Back At The First Three Years.

May 19, 2020
When we started our 2002 Chevrolet Silverado 2500HD project back in February 2017, we had a pretty modest plan in mind. The truck was purchased off Craigslist for the sum of just $3,800. It was a crew-cab four-wheel-drive model with the body in great shape. Problem was, most of the engine accessories were in either the cab or bed. The previous owner had also picked it up cheap and stopped short while trying to rebuild the Duramax diesel engine.
At first, we thought we could simply finish assembling the engine and drive the truck. Upon further inspection, however, we found a scared piston, badly damaged head, bad fuel injectors, a worn out CP3 high-pressure injection pump, and more. With that, we threw our first plan out and set to devising a new one. Knowing that a full teardown was going to be in order, we planned out a series of modifications that would net us a reliable drivetrain while hopefully producing between 600 and 700 rear-wheel horsepower.
Along with the power and reliability, we also wanted to lift the truck with the smallest kit that would allow us to fit a 37-inch tire. Ultimately, the truck will serve as a tow rig for our off-road toys and maybe a bit of an overland adventurer. It also needed to still be street-friendly.
We started the build in the pages of Work Truck Review magazine, along with 8-Lug magazine. It has since jumped over to include Diesel Power and Truck Trend. The project continues on today at TruckTrend.com and FourWheeler.com. To date, there have been 27 installments of the project build, and we're not slowing down yet. Click through the links below to check out what we've done thus far, and keep checking back for more updates on this fun build.
