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

Product proves excellent quality, practicality and easy to use as noted by multiple customer reviews. The kit is well-engineered, complete, cost-effective and has been called the "most complete kit out there". It provides "the best bang for the buck" and a great time-saver compared to "scratch" builds. Notable features include providing more room for customization and being suitable for different car models. Speedway's targeted at 50's cars but can handle 30's cars with slight challenges. On usability, the kit could improve by providing better instructions, and clearer, detailed directions. Some users replaced its Heim joints with ones from ''Rod End Supply'' but overall satisfaction high. Despite minor dislikes, product’s recommended for projects due to speed and overall quality.

Because no instructions are included the end buyer either has to A) go back to the Speedway motors website and download/ print. Or B) guess how things are supposed to be torqued, welded, and installed.

On the 56 1/4 ford spindle axle what is the width measurement from center to center on the leaf springs? Also are they adjustable width? Do you have a pitman arm and drag link that would work with this axle for a 1965 Dodge Dart with a power steering gear box?
