Can someone explain how pinion snubbers work on a Mopar? And why do they need to be adjustible?

I find in the descriptions - "Helps control wheel hop and axle twist"

Thanks Moparts!

As the housing twists, the snubber contacts the floor of the car and prevents more wrapup. Adjustable allows you to dial in the distance you want between it and the floor to provide optimum results without constantly bottoming out.

BUT with proper springs ... there will be no wrap-up ...and the pinion angle should not move anymore that 3-5 degrees at the most.

As many chassis builders have said ... a PS is just a band-aid for INeffective rear springs.

Must be Chevy chassis builders. A mopar rear spring at it's worst will outperform a good brand X spring. There are some out there who can and do twist axle housings. (Not me of course.) A snubber will prevent this.

TELL us all then .... how many "national event quality" NHRA/IHRA Mopar class cars that use regular or SS springs .... also use a PS ?

A pinion snubber works much like a traction bar. as the spring wraps, the snubber contacts the floor to stop the motion.

This has me confused because so many people rag on guys who have traction bars on a Mopar. It does the same thing, only it has one contact point.

I would rather use a traction bar system that uses two points of contact, that are closer to the wheels. It makes more sense to me to have two contact points as close to the wheels as possible (since the two tires may be on varied surfaces causing different wrap up on each spring) than to have one central contact point.

Care to name the TOP five on your "list" ?

Are you aware that the Chrysler race program some time ago actually almost dictated that you run one ?

But the "correct" spring will not do this.

Most guys that have traction bars on a Mopar have the wrong ones on there. They stick past the front hanger by about 6-8 inches. Southside Machine has a nice set that fit. I don't think they slap but instead they clamp to the front of the spring instead. It's been a few years since I've seen a set so I can't remember exactly.

Namvet, Thats a bunch of crap. if thats the case why do they use ladder bars or traction bars. Whoever told ya that obviously dosent have the torque to flex a spring.

Crap ? ... then give me your list of which well-known Mopar class racers that DO use a T-bar on a race-car with a leaf spring rear suspension.

And a ladder-bar suspension has NOTHING to do with this conversation.

I dont know, isnt a ladder bar just a fancy traction bar? You can use them on leaf spring cars, and they stop axle wrap, and create a lift point on the chassis of the car...

The leaf springs will last longer with the help of an adjustable snubber especially if you have slicks, power and a little traction to start with. When adjusted correctly they help plant the tires when you hammer it. The first mopar I raced alot had HD springs and no snubber, ran mid 12's and developed a nice air gap between all of the leaves just outside of the U-bolt-clamped area. Now I use the snubber.

Sorry ... no .... a ladder bar suspension is a separate and distinct animal. A LB suspension should totally eliminate any up and down pinion movement.

A snubber just stops the point of flex at the center, traction bars put it on the springs. All the traction bars do is slap the springs,I'd much rather push on the body rather than the springs! Way more effective. whats the difference except the price. You must be a Chevy guy.

Chevy guy ? .... I have never owned anything but a Chrysler product. I even have a Chrysler powered drag-boat.

You like a PS ? ...good for you.

Care to answer my Q posed before ...about Chrysler almost dictating the usage of a PS ?

Never said Chrysler dictated the use of one, in my opinion they work. I know of a few 9 sec. cars that use them and SS springs and would hook on a dirt road. No need for that silly stuff hanging all out for all to see.

wow, I don't know what to say about this. When i bought my car a buddy of mine who has raced mopars for years said make sure you have an adjustable pinion snubber. (it does). When I bought it, it had new ss springs. Now about 4 years and 4,000 miles later the snubber which was about 3/4" from the floor is now resting on the floor. Were my springs junk? Of course when I drive it, I have my foot into it about 90% of the time. Kevin

A wheelie bar will do the same thing which is one of the reasons for not using a PS
Dick Landy used snubbers BTW. He's the one I made reference to when it comes to twisting axle housings.
