Post by Anonymous »

is fitting an adjustable pinion snubber a good idea even if i am only going to have a go on the strip a couple of times in a year?
if yes, why and can i get one in this country?

It fits on the top of the nose of your pumpkin. When you nail the car the axle wants to twist. The snubber contacts the floorpan and stops the wheels "hopping" as the axle loads up and back. Chevy boys and Ivor (Check last years calendar ;) ) use "slapper" bars that bolt under the axle spring perches and contacts the front of the spring.

To answer your original question Sean ;)

We've got a snubber for the Dodge for when we get out on t'strip. But having read up on them a bit more, I'm not to sure whether we need to use it :shock:
see http://www.moparstyle.net/forums/printt ... hp?t=65157

Old school Mopar guys swore by them but lookin at the discussion in that link, looks like they dont contribute anything if you've got super stock springs set up right.

If you do use one, set it to have 1/2" clearance between it and the underside of the car, with you in it.

If your SS springs are set up right, you car will see seperation between the body and the axle under acceleration. With this condition, the snubber isn't going to be doing anything but going along for a ride
.

I posted pictures of my launch a while ago & the above statement is correct, so I fail to see how a snubber is adding to the launch.

I do have one (adjusted as stated above) and Super Stock springs; so I will do some experimenting when the times & 60 foots settle down to a degree of consistency.

I would like to point out that in the interests of maintaining Mopar traditions, which support the theory that Chrysler's rear axle and spring geometry negates the need for traction bars, I have already removed the slappers and will be fitting a set of five foot long Lakewood ladder bars, omce I've got the cars jacked up 22 inches over stock ride height and fitted the tube front axle...

The only thing a pinion snubber can do is stop axle rotation in the split second that you nail the throttle, and at that point it is doing 2 things, helping to prevent wheel hop and helping to maintain the pinion angle initially, which could prevent a breakage on the driveline. Once the suspension has started to rise it will be too far away from the floor to do anything. The hardest hit the driveline will see will be that initial blow, so anything you can do to keep things under control has to be a good thing, that's the way I see it any way. I would run an adjustable snubber if you are going up the strip but don't forget to back it off for street use unless you want it pounding a hole in the floor when you are 4 up or laden down on a beer run........
