Autofab starts each lift by first installing new beam pivot bushings and then straightening the beams to their original condition. The beams are first bent for lift camber then the king pin end is twisted for caster alignment using Autofabs proven specifications. Recommended tire size for our 5-inch lift package is 33 to 35-inch tall tires or the metric equivalent.
Our 5-inch lift kits include Autofabs’ extended radius arm package, the extended radius arms, new radius arm bushings, new radius arm hangers, and all grade 8 hardware. We extend the radius arms, on the 5-inch lift, to ease the angle on the radius arm bushing. Our radius arms are either the formed and welded steel or forged steel radius arms, depending on the year of your truck. Most 1965 to 1973 trucks come with forged radius arms. 1974 to 1979 will usually come with formed and welded steel radius arms. We also provide our custom fabricated radius arm hangers. Our hangers are made to accommodate the increased angle of the radius arm bushing after the truck has been lifted. We also offer race quality heim or rod ended radius arms for the ultimate pivot structure.
All of Autofabs ’65-79 Twin I Beam lifts include our own adjustable tie rod or drag link to the right wheel. This tie rod allows proper toe-in adjustment of both wheels independently of one another while keeping the steering box in the center of its’ travel. This is very important for your truck to drive and steer correctly after lifting.
A $900 core charge for beams and radius arms will apply to this kit. We do not manufacture beams and need good parts to continue.
This lift requires either a core charge and return of your good used beams and radius arms, or your good used parts for us to perform the work on. If you would prefer for us to perform the work on your parts, then a core charge doesn’t apply. But you will need to send us your parts first. Turn around is usually 3 to 4 weeks, excluding shipping time.
Please note, this is a non-stocking item, each lift is made to order.
