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.

I have personally found that speedway put a lot of time and effort into there kits like this and that really helps the end user. I have purchased a lot of stuff from speedway and I have yet to be disappointed.

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.

Using this to replace the parallel leaf setup for my 1929 DeSoto. I substituted a 4" drop axle, and it lets the car sit right.
