They will work but they are made to have the torque tube in there. If you add "traction bars" from the bottom of the U-bolts up to the frame they should be ok. Other wise, they try to wind themselves around the axle tube if you get on it. Those springs are not very rugged.
3 here with at least 20 years of use each, no issues. The one car with more hp does have traction bars.
Pickup springs are some different than the car springs. The '38 pickup in the avatar has original springs, a '55 Pontiac rear, no traction bars, and in the long gone past has experienced a variety of engines. Currently a GMC 270 and am threatening it with a GMC 302.
Yes, the wheels are off set ,not centered.Once in a while front inside of tires will rub on inside fender well on a turn because of it. Wonder if thinner tires would clear.
I have been running 39 springs in my coupe for 40 years.I worked in a spring shop,and made a pair of "wrapper"leaves for the springs,like a lot of medium duty trucks use.The wrapper wraps tightly around the front eye of the spring and out almost to the rear eye on the main leaf.I used a 71 camaro rear end,and just drilled the holes for the center bolt a couple of inches ahead on the camaro spring perch. I have run various blown small blocks over the years. I had a 6-71 blown 400 in it,and changed to a 9" bronco rear,I bought a pair of ******* bars at a swap meet for $10.00 and modified them to fit the 39 springs.I currently have a 6-71 blown 350 in the coupe,with a street fighter high stall converter.I have no spring wrap problem with this setup.
sorry i should have explained better. I've been running them for 10-12 years with a maverick rear end.When i hit a bump, it seems to come down like a buckboard. i wonder if the shocks are bottoming out. i also ran these springs when it was a stocker still have the wrapping on them.Maybe it's not the springs after all.
