When purchasing a Chevy Silverado 2500HD 4 inch lift kit don't trust your truck to anything less than a Tuff Country EZ-Ride Suspension lift kit. More than your average lift kit, all systems are engineered to give the highest quality & best value on the market.

Tuff Country #14993 "Strong" Chevy 2500HD lift kits use new extended steering knuckles and a three-piece sub frame that includes two cross members that are connected by a heavy duty skid plate. This skid plate is designed to protect the front differential and stabilize the cross members for unmatched strength and durability. This design also allows for an easier and quicker installation. 2 inch cast iron blocks lift the rear to level the Chevy Silverado 2500HD. Differential drop brackets and torsion bar drop brackets keep everything in alignment.

Will this Part #12904 tuff country leveling kit work and b safe on a ’05 Chevy 2500 HD 4X4 DIESEL????? I ask only because I heard they will NOT due to the xtra weight of the Diesel engine but want to be sure.... Thank you for your time!!!
Yes, Tuff Country part # 12904 is designed for the 2500 Diesel. Part # 14993 the 4" also works on the diesel.
Hi I have the 4 inch lift do you sell a set of replacement spindles Thanks mason
Yes we do, you will have to call and order these over the phone. Call 800-903-2760
What's the difference between the 14993 and the 14985 for a 04 chevy 2500hd
Part # 14993 uses a (3) piece front sub-frame, the 3 piece makes the install a little easier. One person can install this kit. Part # 14985 uses a (1) piece front sub-frame, it takes more than 1 person to hold that up to mount to the vehicle. So bottom line Tuff Country designed the 3 piece kit to make it more installer friendly. The end user the ride is going to be the same. One other nice thing with kit # 14993 is the heavy duty front skid plate that gives you extra protection.
