Im removing all of the stock rear suspension and 8 3/4 rear end and am replacing it with a Dana 60, Caltrac Mono Leaf springs, and CalTrac bars. I plan on running a 29" tall tire...which ride height do I need? Stock ride height or +1?

I originally ordered the +1 shocks but only had about 1" compression and had to send them back and they swapped out a Std set. Hoosier 29.5 x 12 slicks Last edited by Moparrob68; 04/20/21 08:55 PM.

I do like the stance with them, but i think the stock height springs would look just as good. BTW, boy that Coronet R/T above is absolutely gorgeous. Love the color combo! 1.50 60Ft. , 10.75@ 127MPH Hauling 3900 LBS.

I had a 30x9 slick under it and it fit without the the 1" spacer, and fit well. I now have a 31" tire with the spacer. It's a wee bit tight. I also have sliders; no shackles...fwiw. My next plan is to install wooden spoke wheels of a horse drawn buggy.

Street tires are 31 x 16.5 M/T sportsman pro's on 15 x 12", 7.75 backspace custom Cragars. 31 x 13 M/T ET Drag slicks on 15 x 12, 7.5BS Welds. I bought the Welds used with the Hoosier 29.5 X 12 slicks and ran them for a weekend. Car ran the same 9.85 @ 136mph with both size slicks but it looks so much meaner with the 31 x 13's

A lot depends on where the springs are mounted so don't forget the eye height.

My old pump gas Duster with ladder bars and coil overs(15.0 inch extended with 7.0 inches of travel with 300 Lbs. rated springs) with a diagonal link never bound up or did anything worth complaining about in my opinion I drove it on the street for over 3000 miles and put hundreds of passes on it, love it You need to keep in mind that I'm a drag racer and love going fast and quick, not looking for a Lincoln or Rolls Royce ride either That rascal would hook up in a mud puddle in a rain storm also AKA aside, I loved that set up Mr.Cab Racing and winning with Mopars since 1964.
