Mopar performance pinion snubber doesn't fit?

[Malicious]

Hi All,

My pinion snubber disappear at some point, I noticed when I swapped the centers out, so I ordered in a Mopar Performance one.

I've got a pair almost brand new XHD springs (maybe 1000km at best) on my 68 Coronet and it doesn't fit. Too tall even on the lowest setting.

I saw a review on Summit Racing saying the same thing. Seams daft that an adjustable one can't go low enough for the intended car with new XHD springs!

Is this common? or am I the daft one?

With the holes for adjustment,you might be able to shorten it.,,,,,Good luck!

I thought about shortening the male piece with the rubber, but the rubber bottoms out on the opening female base piece. I would have to shorten them both.

Considering the cost of the Mopar snubbers locally, I was thinking about selling it and buying a stock one. The Mancini one also looks fairly tall, but I might email them on the lowest height it can achieve as an option.

The XHD springs are basically stock height, cutting both male & female pieces should work.

Don't get excited, this happened to me too. You have a few options which you're probably already thinking about. I cut about 1/2 the rubber off my rubber bumper. Just measure twice and cut once. You can trim down both the inner/outer parts of the adjustable part. Drill new holes in them if you need to. Cut down the bumper. Change the bumper out to a different one. Pick your poison.

I personally don't like the stock pinion snubbers since they don't do anything. If you wind up a rear end enough to hit the stock pinion snubber you've got problems. The adjustable one's work great in my opinion. If you absolutely can't fit the pinion snubber in there, the maybe add some cheap traction bars...which do about the same thing as a pinion snubber.

For a drag race application, I never considered the pinion snubber a significant part of the suspension package. In fact I took mine out and relied on the spring package and shocks to make the rear suspension work. For street use they protect the U joint & floor pan from big bumps in the road. Cutting the male/female parts & the bumper can get the clearance. You may also want to check the pinion angle to be sure that's not pointed up.

Not an authority on this, but I think the adjustable snubber was developed to use with Super Stock springs.

If this is a road car I don't think you'll be happy with your snubber an inch from the floor board.

Thanks for the feedback guys, I might look at cutting it back, but I have a few questions I hope you could help with;

I was looking at a caltrak (slide-a-link etc) style system in the not to distant future. Would that negate the need for the snubber?

Why would I not be happy with a snubber an inch of the floor for street driving? Is it likely to contact with the floor alot during street driving and become annoying?

I have also been meaning to check the pinion angle as I had a mystery vibration, but I managed to solve that with a few other things so I haven't gotten around to checking the pinion angle. I'll add it back to the list.

Amen to that!! And I thought I was the only one that hated those things. After hammering floor boards (you need to reinforce it if you have enough power) and peeling the rubber off, I started doing the same thing and with great results.

IMO, yes. Add a couple average size persons in the back seat and drive over a few small hills at 50 or so. Likely those folks two in the back will be telling you something is surely wrong with your car.
