Suspension gurus please chime in.

[66 440]

So while investigating my new purchase I discovered the my 66 Coronet is missing the pinion snubber. I am redoing the suspension as the car has been switched to air shocks some time ago. This is going to be a touring around pleasure driving car that I will stand on once in a while so I don't need anything extreme.

Wondering if I should do a shock/spring/pinion snubber combo or if I should bite the bullet and do shocks/springs/caltracs. The car has a 67 440 HP from a GTX with a purple camshaft, stock HP manifolds etc. Unfortunately I don't have any other engine rebuild specs. 3.91 8 3/4 rear end and a 727 torqueflight tranny unsure about converter etc.

Any help would be appreciated as I figure over the next 2 months I will poke away and get it ready for spring. I will apologize in advance if the question is silly as I am new to this and ....well I am Canadian and we apologize for everything

Thanks

I know I may get blasted but I'm not a big fan of the snubber for a street car. It works well on the track if adjusted correctly so it can make contact when the pinion gets rotated too far but that setting used on the street can also have you feeling the thump when you hit a dip in the road. I prefer the caltracks with a good set of springs, not too firm. That combo will control axle hop and give a good controled ride on the road.

For what you want to use the car for, the factory set up would be fine

Yep on both ! You will be takeing it back off after a couple Jaring bumps that feel like the rear just came through your back seat !

1st off I would dump the air shocks in the garbage can. Makes the car ride like a hay wagon and likes to tear up shock crossmembers.

I run Cal-Trac's on my roadrunner and they work great. Better than a pinion snubber, but that's not to say a pinion snubber don't have it's place (especially the adjustable ones). Like these guys mentioned, probably would work fine for your scenario. One thing to mention about the Cal-Trac's, they with noticeably harsh up the ride. As soon as you add preload from the Cal-Trac's, you can notice a flex starting from the front of the leaf springs. I did take all pre-load off the cal-trac's to see how the ride was. As mentioned, noticeably more plush. But, with almost 700 Ft/lbs or torque, it was like a tornado on a roller skate. I took the trade off of a harsher ride, for decent traction and being able to get the car to launch straight.

I know my car is alot heavier than yours but I have S/S springs and no snubber on mine ('77 Cordoba) and it rides like a dream on the street and launchs good on the street and the track. Cal Tracs seem like overkill to me.

i run the adjustable snubber and mopar perf springs.by far the most cost effective way to go on the street and you can adjust the snubber to the way that best suits your needs.
