Installation Tips

If using steel wheels with Wilwood kit, you will also need to purchase (2) steel shims part 835-3007500. These shims will prevent steel wheels from galling the aluminum hub.
Rubber brake hoses generally cannot be adapted to Wilwood calipers. The caliper inlet fitting is a 1/8-27 NPT. The preferred method is to use steel adapter fittings at the caliper, either straight, 45 or 90 degree and enough steel braided line to allow for full suspension travel and turning radius, lock to lock.

Overall Assessment

Customers highly recommend this product for its high quality and practicality. Key features include ease of set up, expert machine work, quality fit, and the ability to exceed expectations. It makes gasser dreams come true with well-machined parts and easy installation that is well suited to a first-time Gasser build. However, improvements are needed on assembly instructions. The product stands out for enhancing the look and performance of vehicles like the HenryJ and 56 Chevy gasser. Some customers did express dissatisfaction with the axle assembly, but compared to competitor products, our product clearly receives more positive reviews.

i would not buy this product again

not much thought put in to putting this axle assembly together. the king pin at the axle has too much clearance and only has a allen screw to take up the slop. the spindle dust caps as I was told by support they are just glued in top and bottom. if speedway would put one of there axles together they probably would address these issues. they are proud enough to cast there name in the calipers

The straight axle kit exceeded my expectations. Expert machine work and a quality fit that represents a much more expensive price. Speedway is top notch.
