With the lower than stock stance on most of our cars, I assume I am not the only one with a snubber that is pretty close to the floor.

I am currently running a stock snubber and do not have any wheel hop issues, but I do feel like it bumps the floor quite a bit going down the road. Doing so within a turn could certainly be problematic.

Do most of you omit it and run something aftermarket for spring wrap? Stock snubber? Nothing?


My rear suspension isn’t ideal at the moment. I have S/S springs in the low position with additional lowering blocks.

Trim it down to length, and/or increase springrate.
Depending on the amount the car is lowered, you really want a snubber, simply to prevent the driveshaft from digging into the tunnel during heavy acceleration (and maybe some extra load in the back like people.

Thanks. First thing I need to do is validate that it is, in fact, touching during normal operation.

I assume the SS springs have an arch while at rest? If so, I'd concentrate more on replacing/optimizing the leaf spring package and removing/reducing the lower blocks, before spending much time and effort on the snubber solution.


Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

Floor pan will be shiny where it hits, assuming you drive it regular.

There is some obvious contact on the floor surface but it hasn’t worn through the undercoat, the car has 5,000 miles on it.

I measured 0.97” clearance between the top of the snubber and the floor.

Well, I am used to 100k+ miles so it'll be shiny by then, lol. I don't think I ever actually measured clearances but that sound like what I remember.

Another approach could be a half leaf in the forward spring section. Make it a reasonable stout piece, like a cut down main or first leaf. Mount it on top of the main leaf and make sure to add a clamp near the front tip. This provides two benefits, additional wrap resistance under acceleration and reduced tramp under deceleration. The clamped front reduces wrap, the top location reduces tramp. The unaltered rear spring sections allows spring rate to remain intact.

Other methods could be a torque arm arrangement. There are no off the shelf offerings, so this would require some fab work, but could almost be a bolt in depending on design.

I run a stock snubber. actually slightly raised up with a few washers and slightly longer bolts... my Challenger is lowered.. snubber does occassionaly hit (chalk marks on top of the rubber) but nothing serious to be concerned about for me.

stock snubber no issues here, I heard guys using chalk or thick grease to see if they are hitting their floor pan

I'm going to pull the snubber off for a little bit and see what happens. I have to break-in a new ring & pinion, so I won't see any wheel hop issues and can evaluate the ride alone.

From there, I'll assess if the S/S springs need some work or help. Thanks all.

Use the front segment of the leaf springs to control the pinion from rising towards the floor during launch and acceleration. A pinion snubber is a crutch for weak leaf springs.

Trim the rubber so there is no metal to metal contact. This will be a challenge on a lowered car but if it's still hitting you may need stronger springs and or shocks.

So I did some bodywork on the Dart recently and so happened to notice I am 'apparently' not running a snubber...
This weakens my earlier post ofcourse, but in my defence, the experience I have is based on a different car of mine which was lowered more than my Dart.

On the Dart I noticed the narrow 'boss' on the rear-axle snout had made some contact with the body occassionaly but that might very well be from bottoming out once in a while over the idiotic amount of speedbumps we have overhere.

I take the off and never noticed any difference... the adjustable pinion type snubbers are so tall you can’t even drive the car with them on lowered springs
