Speedway Motors 91639510 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.

Overall Assessment

The product, a Super Bell axle assembly, is highly appreciated for its robustness and economic price, especially when equipped on a 1928 Ford pickup. Users are particularly fond of the batwing brackets and radius rods. However, some customers needed to purchase higher quality spring shackles and u-bolts for durability. The easy-to-assemble front brake rotor kit was praised, though notably, the standard drop arms were incompatible with certain kits. Another significant feature mentioned by customers was the completeness of the package, making it a quick and stress-free solution for mounting the front end on Model A vehicles. Overall, the product stood out for its practicality and quality construction.

I like the 4 inch dropped Super Bell axle assy. Good price. I like the batwing brackets with radius rods. I had to buy better spring shackles and spring u-bolts. The shackles bushings were plastic or nylon and they would have never held up. I had to order them from an antique Ford parts house.I'm using this assy under a 1928 Ford pickup. I also ordered a disc brake assy to add to this front end.

[...] I needed a front brake rotor kit with a 5 on 5.5 bolt pattern. The only one available was the 11.75" Impala conversion. The front end kit went together extremely well until I came to the drop arms, which would not work. I went back online to get the customer service number to see what was going on. Before calling I went to the online catalog page to get the part number of the rotor kit. And there is bold print was a note saying the standard drop arms will not work with this rotor kit. It gave the correct part number for flat drop arms. I ordered the right ones right then and sent the ones I had ordered wrong back. [...]

Does this come with the shock mount shackles? The description suggests pairing the Pro Shock SM300 shocks with this front end but I do not see if the kit comes with the appropriate shackles.
