Model A Parallel Rear Four Link Kit

Welder Series carries two varieties of parallel Model A rear four bar kits. The only difference in the two kits is the frame brackets; the kit for stock-style frames incorporates the tapered rear frame rail, while keeping the bar mounting holes vertical. Kits now use the larger 1-3/4" wide urethane bushings and 3/4-16 threaded adjusters. Kits are supplied in both welded and ready to weld versions. In the ready to weld kit, the customer is responsible for all the welding.

Grant Schwartz has been using this kit in late 50's GMC pickups and other trucks where the frame doesn't kick up much over the rails.

This kit is designed for Model ‘A’ Fords with the frame rail tapered from a side view. Many repro frames also incorporate this taper (Total Cost Involved, Brookville, Pete & Jake’s, and others). The bars mount below and outside the frame rail. The frame bracket holes will be about 25-1/2″ ahead of the rear axle centerline. This will clear TANKS saddle tanks. Rear axle brackets have 3 mounting holes for the coil-overs. Bars are 1″ heavy-wall seamless mechanical tubing, tapped one end 3/4-16 RH and notched for the 21309 tube on the other end.

This kit is designed for aftermarket frames using rectangular tubing rails without a taper. The bars mount below and outside the frame rail. The frame bracket holes will be about 25-1/2″ ahead of the rear axle centerline. This will clear TANKS saddle tanks. Formed rear axle brackets have 3 mounting holes for the coil-overs. Bars are 1″ heavy-wall seamless mechanical tubing, tapped one end 3/4-16 RH and notched for the #21309 tube on the other end.

Both kits include: Bars, adjusters, frame brackets (with support plate), axle brackets, bushings, and hardware.

Grant Schwartz uses a slightly modified version of this kit on F100 pickups... he notches the bars to kick the axle brackets outside the rails, then mounts the coilovers to the side of the frame.
