This premium lift delivers a leveled, aggressive look while enhancing ride height and off-road readiness all with an easy bolt-on installation.Engineered for Superior Ride Quality: This kit includes application-specific front lifted leaf springs, delivering increased ground clearance without sacrificing ride comfort or control. Rear lift blocks and brake line brackets maintain proper geometry, ensuring a smooth, factory-like ride after installation. For a complete suspension upgrade, the kit is also available with replacement rear lifted leaf springs, offering consistent rear lift and eliminating the need for lift blocks.Enhanced Performance with N3 Series Shocks: Rough Country's N3 series shocks come standard valved for your exact application and designed to provide a perfect balance of on-road smoothness and off-road capability. Featuring a 10-stage variable valving system, high-pressure nitrogen charge, and durable 54mm shock body with 18mm piston rod, these shocks are built for performance and longevity.Room for Bigger Tires: Make room for aggressive wheel and tire combos. This 4" lift offers enough clearance to run up to a 35" tall tire with proper backspacing, giving your truck the rugged stance it deserves.Improved Steering and Handling: To maintain proper drivability, a raised steering arm is included correcting steering geometry for tight, responsive handling after the lift.Limited Lifetime Warranty: Rough Country backs this kit with a Limited Lifetime Warranty, giving you long-term confidence on and off the road. Note: If vehicle is equipped with a front sway-bar, drop brackets are recommended RC1019. Optional Rear Springs: To confirm rear spring size a measurement will have to be pulled from eyelet to eyelet. Vehicles with factory quad shocks (2 front shocks per side) will simply use a single aftermarket shock.

  • Great product. Excellent price.
Great product and great price. Highly recommend.

  • Very nice lift however....
Very good quality parts and installation is easy enough other than the control arm swap. (Have a torch and a sledge hammer ready) It rides great, very smooth and fit perfectly on my 82 K1500. Only downfall is I had a 4 inch lift but it was old and worn out. I just wanted to keep it the same. This is not a 4" lift. The blocks are but that's it. The front is a 6" I will now have to buy 6" blocks to level my truck and an adjustable drag link to fix my steering or now lack of. That's another $200 I really didn't care to spend. Other than that it's a nice lift for a fair price ... show more

  • Rough Country is a good and affordable lift—great customer service
Great product—Actually could be considered a 5” kit—only issue was had to purchase 5 “ blocks to get to sit level—-overall everything was good—

  • Does the job, kit is pretty minimal
Its a discount lift, probably the cheapest way to lift your truck, but its a bit sad how poorly its thrown together. comes with bushings and stuff you dont need, but also doesnt include any replacement hardware. these trucks are old as dirt now most of the hardware is in rough shape if you get things off without cutting. It could include new mounting hardware for shocks and springs etc. Especially new conical washers for the steering arm it only includes new nuts for some reason. the instructions are pretty awful, something out of the 90s at best. Its pretty straightforward but still. some laminated color instructions would be great. ... show more

  • Got The Squats - Truck sits lower in the back, wrong parts
Will not buy rough country again. The front u-bolt was incorrect. The front leaf springs are for a 1-ton. I wanted a 4" lift, bought a 4" lift. Got a rear 4" lift and a front 6" lift. Trucks looks stupid as it sits 2" lower in the rear. My rear leafs are not worn out as the truck didn't sit 2" lower before the lift. Front is clearly a 6" lift and rear has 4" blocks. I ordered 6" blocks for another $150. ... show more
