I 've seen this too. Some differences beteen this and DSE. DSE has patented swivel links and high durometer rubber bushed ends. Important if NVH is a factor for the end user. I like the panhard bar on top of the axle if you are using a stock fuel tank. Packaging may be easier. The DSE uses a longer upper link which reduces pinion angle change but is more of a bolt in.

Treed me! Was just going to tag you and ask about how the DSE kit compares! Which part number DSE kit are you selling? It’s a GM kit that’s being adapted right?

Great insight on that! I’m not a 4 link expert by any means, but I know that little differences in the link lengths and the angles they sit at are really important for roll centers and pinion angle changes.

A lot of that comes down to application, on a street car plenty of people are happy with triangulated 4 links like the RMS. But for a more serious autoX or road course enthusiast there’s a different level of tuning and optimization and some of those little geometry changes can be really important.

That panhard bar above the axle looks kinda slick for space considerations and a stock tank
