We never ever ran a snubber
When SS springs are working the car body separates from the springs and you could observer the 'rise" as distance between the body and the top of the tire grew larger upon launch
a snubber was used when they used a four speed, side stepping the clutch at some zillion RPM's and the deal was so violent that it would kick the back seat cushion out--THAT was when they thought of snubbers
SOON afterward it got better fast
BUT the snubber continued to be top seller easy to make so...duh keep on selling them not hard to understand
Do you need one?/ Heck NO!!! Do they sell??Sure! so duh......
