The old iron Dodge W250 \ W350 are workhorses with the heart of a warhorse. Invest in your trusty Dodge with a premium, proven long lasting suspension system. Give your durable Dodge W250 \ W350 Diesel a new life with a new lift. Skyjacker Softride(R) leaf springs are individually shot-peened with hard steel pellets at very high velocities. Softride(R) springs also have tapered leafs to distribute loads more evenly and to create more flex at the leaf ends. Teflon(R) wear pads between leafs and bolt style spring clips prevent binding and eliminate friction. Skyjacker's engineered processes achieve maximum wheel travel, ride quality and extends the long-lasting life on these Diesel Specific replacement front leaf springs. Includes front u-bolt kit and Polyurethane spring eye bushings with replacement sleeves. OEM rear leaf springs remain. A high-quality block \ u-bolt kit lifts the rear. ADX 2.0 Adventure Series Remote Reservoir Aluminum Monotube Shocks exceedingly enhances front and rear dampening. ADX 2.0 offer unmatched shock damping and have specific valving and stroke for this application. ADX 2.0 has an innovative off-road race-inspired full-displaced valving system. Engineered for higher speed applications, remote reservoir shocks still perform at low speeds. The external remote reservoir separates the nitrogen gas from the oil with an Internal Floating Piston (IFP). The majority of the reservoir contains pressurized nitrogen gas. The IFP prevents the gas and oil from mixing or foaming (cavitation). Nitrogen charged with IFP Technology = Quickest Shock Reaction Time Ever. From higher speeds to a slow advance, ADX 2.0 works.

Skyjacker 4In CUMMINS DIESEL MODELS - D400CDK-X FAQ
The maker's installation guide is on this page — see Installation guide under the part details for the step-by-step and the torque figures. Work on level ground with the car properly supported, and torque every fastener to the maker's figure. If the job is beyond your tools, any shop that does this kind of work can fit it.
Yes. Any change in ride height changes the alignment; set it once the kit is on and the truck has been driven a short distance.
The maker states the largest tire the kit is designed to clear; going larger can need trimming or more lift. Wider wheels with less backspacing also change what clears.
Taller lifts change the angles of the driveshaft and CV joints, and kits made for that height include the parts to correct them when needed. A leveling kit that raises the front a small amount usually does not.
A leveling kit raises the front to match the rear and keeps the stock springs and shocks, so the ride stays close to stock. Larger lifts with new springs change the ride more.
Some kits reuse the stock shocks and some include or call for longer ones; the Part details and the maker's guide on this page say which.
Trucks with headlight leveling, adaptive cruise or a forward camera may need those systems re-aimed after the height changes.
Yes — monthly options show right under the Add to Cart button. Affirm, Klarna, PayPal Pay Later and Snap Finance are offered at checkout, and checking what you qualify for does not affect your credit score.
Install and care: lift kits
Before you start
- Read the maker's guide for the tire size it clears and whether longer shocks or driveline parts are called for.
- Book an alignment and, on trucks with cameras or adaptive cruise, a re-aim of those systems.
Do
- Torque every bolt to the maker's figure and re-check after the first drive.
- Align the truck once the height has settled.
Don't
- Don't run a larger tire than the kit is made for without checking the clearance.
- Don't skip the driveline parts the maker says a taller lift needs.
