They were absolutely meant to work together. SS springs were designed around a snubber type of system.
Things like slappers and Caltraks are fine for use in press-tube style axles, but on an 8.75 are a REALLY bad idea, even on one that is back braced. The front of the housing that supports the chunk is still subject to the torsional load and will either distort or tear over time. A snubber negates this.
Biggest issue with a pinion snubber, us that it is almost too simple and effective. Nobody can make any money off it, so it's ignored.
Match race Funny Cars ran deep into the 8s back in 65/66..the snubber was their ONLY traction device. The **** flat out works.
As for the lack of undersranding of this device, blame it on the Ford and GM guys.
Mid sixties Mopars were the only ones built on a unibody platform.
You couldn't use an effective snubber on a chassis car, because it would be working against the body mounts.
As a their suspension science evolved, it cross polluted ours.
