Description:

After years of testing, from daily driving to harsh off road terrain, heavy hauling and everything in between, the Kryptonite 2.5"/3.5" Dual Rate Lift Coil Spring set is now available. This is the most durable and premium spring option on the market. Designed with heavy duty truck use in mind, this spring provides rugged load handling capabilities while maintaining an extremely comfortable ride. Using top rated material we can produce a plush ride with minimal spring sag. Our true Dual Rate Spring can truly provide the best of both worlds. Mile after mile our springs will hold up to any truck, and any job. Installing these coils on a gas Super Duty will result in a VERY stiff ride. We DO NOT recommend this whatsoever. 

2.5" vs 3.5"  Explained

You may notice our springs, and other manufacturers, have Ford springs listed as 2.5"/3.5", depending on the year. The answer is quite simple, the 2020 and later Ford Super Duty trucks sat 1" lower from the factory than its predecessors. This means the same 2.5" leveling coil on a 2005-2019 Super Duty will provide 3.5" of lift on the 2020+ Super Duty. No other parts changed, the truck just started out lower than before. The only time this is not true is for the 2020+ Super Duty TREMOR, these come from the factory with a 2" lift/level, and makes them 1" taller than a stock height 2005-2019. Using our 2.5"/3.5" spring will lift the front of a 2020+ TREMOR 1.5".
