Heavy trucks need suspension engineered for their weight, not half-ton parts with stiffer springs. LSK's 2500HD line covers 00-10 Silverado and Sierra HD trucks with King 2.5 remote-reservoir front and piggyback rear shocks, and 11-19 trucks with upper control arms and full race kits in 2WD and 4x4. These platforms tow the trailer all week and chase the race truck all weekend, so everything is built around real load: arm strength, shock valving, and geometry that keeps an 8,000-pound truck predictable at speed in the rough. Specced and built in Fontana, California — tell us how your HD gets used and we will valve it for that.
Chevy / GMC Silverado 2500HD — Common Questions
Do you make suspension for both 2500HD and 3500 trucks?
Yes — the 00-10 shock packages fit Silverado and Sierra 2500, 3500, and HD trucks, and the 11-19 line covers 2500HD in 2WD and 4x4. Check each product page for exact fitment.
Can a 2500HD really run long travel and still tow?
That is the point of building it correctly: King valving and spring rates are specced for the truck's real weight and duty, so it can tow during the week and run chase at speed on the weekend.
