Not sure anybody can dispute Bill at RMS was/is the longtime leader/innovator on quality aftermarket front ends for mopars. Only thing that bothers me more those without enough talent to design their own better"mousetrap", and then hide behind a copy, is someone who makes the mistake of copying a bad design.
I never stopped shaking my head on Bill's "upgraded" rear mopar 4 link suspension offering, and have seldom bit my tongue in that regard, but to resort to copying it, speaks volumes to me.
The comment above is in reference to the gerst rear 4 link suspension system.
While on the topic:
"A triangulated 4 link uses short and long control arms set at opposing angles to help keep the rear axle located and relies on a separate spring and shock for controlling travel over bumps and body roll control. Maybe a little better than leaf springs the 4-link still has issues with suspension bind in cornering as the upper and lower arms travel in different arcs. To compensate for this GM control arms are flimsy with rubber bushings to allow a lot of flex for a smoother ride but that means loose and lousy performance. When you make these arms solid and stiff plus add stiffer bushings it actually creates a worse bind situation and can cause a 4-link car to become more twitchy, less predictable, throw off the front suspension travel and lose traction everywhere."
