Q & A

What's in the Box

Four bar suspensions allow your front axle to travel freely, thus providing better ride and handling than traditional radius rods. Plus, their polished stainless construction will keep your front end glowing forever! Speedway kits feature bat wings and tapped bar ends, complete with nylon rod ends. For axles with 2" or 2-1/4" boss - use spacers 916-35003 if necessary.

For 1928-1931 Ford Model A.

Notes

We strongly reccommend the use of a front panhard bar with four bar front suspensions. Four bar suspensions increase suspension travel over original wishbones or radius rods, which increases the need for side-to-side axle control. If using a Vega cross steering system, the panhard bar becomes mandatory as any side-to-side movement will cause bump steer.

Plain Tie Rod/Drag Link Kit with 11/16 Tie Rod Ends
                        

These tie rod or drag link kits are pre-cut and tapped lengths of 7⁄8" O.D. tubing available multiple lengths. Kits come complete with 11/16" traditional 7° tie rod ends and jam nuts. Tubing will be tapped with right-hand & left-hand threads for adjustability.

Select your length based on the center-to-center of the tie rod ends, which will also be the eye-to-eye distance between the steering arms (the acutal tube will be 3" shorter than length selected). At selected length, the link will be adjustable from 1/2" shorter to 3/4" longer.
