Super Duty Full Spring Pack
The Carli Suspension Super Duty Full Spring Pack is designed and built to our specification, 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 4.5" front suspension systems. 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. 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 a "HD" Leaf Spring to accommodate your needs. Call Carli Suspension or your local retailer for more detail!
