The new 5th gen Ram 2500 trucks with radius arm front suspensions and coil spring rear suspensions are an awesome platform to build the nicest-riding 4x4 truck you can get. While the factory ride is better than previous generations, there is still a lot of room for improvement. The factory coil springs are still too stiff and you actually bottom out the front suspension very easily just driving on the road. The rear suspension is too stiff when unloaded, however it does ride a lot better once you have some weight on it. For those who aren't always loaded down, we have a really great suspension for you. The improvement in ride quality is unbelievable, and you'll also gain several inches of wheel travel front and rear for those times when you go off roading or are just bombing down some dirt roads.
Our suspension system consists of 3" front dual rate coil springs, 1" rear dual rate coil springs, Fox 2.0 IFP shocks (you can upgrade to other shocks), new end links for the front, and heavy duty adjustable track bars front and rear so you can keep the axles centered. We have tested all of these components on our own 2014 Ram 2500 4x4 and the results are amazing, especially for this price point. There are less expensive "lift kits" out there but none will improve the ride quality like our system does. We don't just want to lift your truck, we want to make it drive and steer better than stock. When you own an expensive brand new truck, you don't want to cheap out on the suspension. Here is what DOR can provide to improve your ride:
3" Front Dual Rate Coil Springs, 20% softer than stock for a very smooth ride and 10" of wheel travel (4" compression, 6" extension from ride height).
1" Rear Triple Rate Coil Springs, 15% softer than stock for a much smoother ride when unloaded and 10" of wheel travel (5" compression, 5" extension from ride height).
Fox 2.0 IFP shocks front and rear, tuned for your truck and these spring rates. You can also upgrade to Fox 2.0" remote resi shocks, or King 2.5" remote reservoir shocks.
Heavy Duty Adjustable Front Track Bar, made from 1.5" OD DOM tubing with an adjustable Johnny Joint at the axle and a fixed Johnny Joint at the frame end.
Heavy Duty Adjustable Rear Track Bar, made from 1.5" OD DOM tubing with adjustable Johnny joints at both ends.
1.25" OD front sway bar end links with 3/4" chromoly heim joints to replace your weak factory end links and compensate for the extra lift without the use of cheap drop brackets.
Optional: DOR 3" long arms using Currie Johnny Joints at the frame and fixed clevis mounts at the axle for a single-adjustable application. The upper and lower arms are 2" OD x .250" wall DOM with 1.25" shank Johnny Joints, and the lower arm bolts into the factory radius arm mount. The new upper arm mount easily bolts to the frame by drilling a few holes. All hardware is included and there is no cutting required. The long arms will provide more tire clearance and fix the coil bow issue, giving you a better ride, more suspension travel, and better performance from the front suspension. The upper arm is bent to clear the body mount and the lower arm is bent to give you more tire clearance than stock. Adding this option will add 2-3 weeks to the build time on average.
With this setup, you can easily clear 35" tires on just about any wheel, and you can clear 37" tires on 8" or 9" wide wheels with 4.5" to 5.5" of backspacing. The truck shown in the photos has 37" Toyo MT tires on Method 17x8.5" wheels with 4.75" backspacing. There is some light rubbing of the inner fender that can be clearanced with a heat gun.
For those who still need to tow heavy, you can add a set of Timbren air bags or something similar and retain all of your factory towing capacity very easily.
This kit fits 2014 through 2018 Ram 2500 4x4 diesel and gas trucks.
Power Wagon models will get 2" front lift and no lift in the back, however you will benefit from the softer spring rates for more articulation and a better ride.
