Details

These front suspension packages make it easier to begin transforming your Model A frame into a rolling chassis. Kits include a 48" I-beam axle, radius rods, leaf spring and shackles. Kit works well with the SM300 Pro Shocks (shocks not included).

Axle kit designed to work with frame #916-57045.

All I-beam axles use the Ford spindle. We have brake kits with both Chevy and Ford bolt patterns available for the Ford spindle.

The brake kit you select will determine the final track width (hub to hub). The brake kits intended for this application (the Wilwood or our 702-4475 Metric brake kit) produce a final track width of about 56-1/4". Some of the other brake kits (like the 916-31903), which are not recommended for this application, would increase the track width by over an inch.
