The Carli Suspension Super Duty Full Spring Pack is designed and built to our specifications, supporting up to 15″ of wheel travel. The center-pin is relocated to accommodate (up to) 38 inch tires, 37″ recommended, and levels the rear perfectly to match our 2.5″ & 4.5″ front suspension systems, respectively. If more lift is desired, one could pair Carli springs with lift blocks to accommodate additional lift; however, this will require brake line extensions and longer U-Bolts (not included). This spring pack delivers smoother suspension cycling in all situations: highway, off road and towing.
This spring pack delivers smoother suspension cycling in all situations: highway, off road and towing. Because of the reduction in tow capacity, Carli Suspension recommends pairing our Super Duty Full Spring Pack with our Proprietary Long-Travel Airbags for trucks that constantly tow trailers with over 1,000lbs of tongue weight, or carry over 1,000lbs. in the bed. For trucks consistently hauling heavy loads, equipped with full time slide-in campers, or running service bodies, Carli Suspension may be able to build an "HD" Leaf Spring to accommodate your needs.
*2.5" leveling 2005-2007 applications require front hanger relocation. Instructions for the conversion can be found here.
Installation Instructions
Customer Reviews
These springs added a lot of stability. Previous ride was terrible. All body roll is gone. All bouncing is gone. Installed in combination with 2.5” coilover kit. The most dramatic improvement came from these rear springs. Highly recommend. Original leaf springs were about 30 pounds. The new springs were easily double this weight.
I have no experience in suspension. I have plenty of tools and jacks. We took our time. Work done in driveway. In my kit I had to drill out the bracket and move it down and bolt on. Also had to re-route the e-brake cable with some fab techniques.
We did one side at a time. Needed two jacks. Also ratchet straps to pull the axle in place after install. Took 5 days. Needed a few tools. One torque was 400lbs. Had to drop fuel tank to install the left side bracket. The frame on my old truck is rusty. This made me want to paint it after installing new components. So we did a partial coating on the frame for appearance.
Excellent support from CJC Offroad. Always responsive and informative. 5 stars. Excellent product. I would do it again easily. It was moderate to difficult effort and requirement as I don’t do this type of work. Very happy though and it was worth it. Sharing some photos of the install and bracket move. Also photo of the spring installed.
Carli Ford Super Duty 05-16 Deaver 2.5" Full Progressive Spring Pack
Great product! Made a huge improvement in the ride quality.
CJC off-road is awesome to deal with
We ordered Carli coil over bypass with upgraded rear springs. Unfortunately the sway bar linkage was missing. I want to thank CJC off-road for going out of there way to resolve this in an extremely fast manner. They have earned my business from here on out. The truck drives excellent with this suspension kit and I would highly recommend CJC off-road.
