4in Ram Lift Kit | 12-21 1500 | Gas or Eco Diesel

Superlift's complete knuckle style suspension lift kit for the 2012-2018 (2019-2021 Classic) Dodge Ram 1500 4WD, providing 4” of lift height and a choice of rear Superlift shock absorbers or rear 5100 Series Bilstein shock absorbers.

• Replacement knuckles yield best possible alignment specs. Front track width is not increased and factory turning radius is retained.
• Front lower control arm crossmembers laser cut from 3/16" material.
• Belly pan, constructed of 1/4" material, connects crossmembers and protects differential.
• Front anti-sway bar link extensions retain factory "service for life" links.
• New Superide Dual Rate rear coil springs provide ideal ride, handling and load carrying capability.
• New bracketry relocates factory rear 4-link points, anti-sway bar links, brake lines and track bar.
• New rear compression travel-stop brackets.
• Rear shock options include Superlift or (SS) by Bilstein.
• Installs easily with only slight trimming and no exhaust or driveshaft modifications.
• Compatible with Dodge's Electronic Stability Program.

On both lift heights, you have a choice of retaining the factory front strut cylinders, or purchasing Superide SS replacement strut cylinders by Bilstein, which noticeably improve handling at higher speeds. If the factory struts are retained, the lift kit includes Superide rear shocks; SS Bilstein rear shocks are included with the Bilstein SS lift.

With Superlift's replacement knuckle system, laser-cut bracketry relocates the front lower control arms and differential, and a .25" thick bellypan protects the vitals while further increasing overall rigidity. For the rear, new coil springs (not spacers) ensure proper functionality and ride quality.

NOTE: TRX4 and Outdoorsman Models - Both 4" and 6" lift kits fit these models, although an additional part number is required if you are retaining the factory front struts (see Accessories). The additional components are not required with SS Bilstein applications.

NOTE: The TRX4/Outdoorsman factory ride height is approximately 1" taller than the standard Ram, so you will gain 1" less lift than stated. When lifted, the standard Ram 1500 and the TRX4/Outdoorsman ride height is the same.

NOTE: Will not fit Short Bed Standard Cab models due to rear driveline vibration.

IMPORTANT DISCLAIMER: The provided tire/wheel fitments are approximate. Actual dimensions of a given tire size can vary considerably from one brand to another. Manufacturers' wheel offset and backspacing measurement points are not always consistent. Backspacing greatly impacts tire-to-fender clearance when turning. Wheel width and backspacing influence whether the tires protrude past the fenders, and to what extent. Considering these important factors, we recommend that you fit-check your tire/wheel selection prior to purchasing.

• Installation time: 9-10 hours
