    Have a 1972 A body with a narrowed Dana 60. Not a mopar Dana 60. So has no way to mount snubber. Thought about buy adjustable snubber from Mancini. Mounting it to the body. I'm afraid that it may tear up the housing without putting a metal plate on the housing for the snubber to hit on... Any thoughts or ideas

    Pinion snubbers stop the differential from sweeping upward through the suspension travel and are consequently extremely harsh riding on anything but a smooth track or street. They do a great job of pushing the rear tires into the ground, causing body separation and increasing traction.

    I run properly adjusted slapper bars on my A & E-Bodies. They ride much better and generate significant traction enhancements. No one makes a bolt on slapper bar that is properly adjusted out of the box, but once modified and properly fit, it is hard to find a better traction solution with a decent ride quality for street strip cars.

      Since your rear has nonprovisions for a snubber, and adding one is probably a bit tricky... and IMO, adding it to the body upside down is not a great idea...

      Use Cal Tracks instead of a snubber. It will be or can be more effective than a snubber and easier to adjust. They are more expensive though.

        I never thot of it, but if done and located properly , it might work. Special reinforcement needed on the body, w/ the right clearance, and a brutal bumper, hitting the rear housing in just the right place.
        We used to tear them up and quit tryin to run one, wasn`t really needed w/ super stock springs, back then.

          I've try getting the car to launch without one. You can't run one on the street so forget about that. I don't use one and mine seems to launch fine.

          If I needed one I'd be going caltrac. That is the very best there is, tried and proven..period.

          I tried Caltrac's on my E-Body, but the ride quality on anything but a dead smooth street was brutal, although slightly better than a correctly set-up pinion snubber that is virtually touching the floor pan.

          I took them off and sold them. Then I put on a two passenger side 2800lbs SS springs on both my 3700lbs A & E Bodies, fitted properly adjusted slapper bars and installed quality shocks.

          The result was the most compliant ride and best handling and hook-up I've experienced in over 3 and a half decades of running these old Mopars.

            You could run Assassin traction bars, they have multiple positions to get them dialed in. I use them on my 69’ Dart with a narrowed Dana 60 with QA1 adjustable shocks. Street ride is pretty nice.

              I have ss springs. Can you run Caltrac with the ss springs

              I will try that without the snubber and see. I've just always ran a snubber with good success

                I had Custom slappers built for my 70Swinger 340/4-speed.... back in 71. They worked pretty good too. On mine I had to remove the factory shock plates. The new shockplates were part of the new bars and, IIRC, mounted the shocks about an inch higher up.
                They weren't great!, but better than the snubber, and the ride was much improved.
