I just replaced the rear leaf springs on my '57 Belair with the 5 leaf replacement units and thought they would raise the rear some over stock height but the didn't.
How can I raise the rear by 1-2" w/o the old-fashioned air-shocks or worse-shackles?? I'd just like it a bit higher than stock. Thanks!

A spring shop can rearch your springs to raise it. They will need to know the weight on the rear axle if you just take them the springs.

How do those work, when the spring is under the axle?

I have the exact same problem with the Nomad that I recently restored. I have air shocks, but would prefer to not have to air them up full tilt to get the stance that I want.
I too have new springs, but still sits too low for me. My local spring shop said that since mine were new that he would re-arch them and get me how I want it.
He said that he wanted me to measure from the ground up to a given point at the center of the wheel well opening, and then lift the car to the desired height and measure again, he would take it from there.
He estimated approximately $80 to $100 cost (pair). I have to remove the springs and bring them to him.

This is the best way, beats the old shackle system lift or using air shocks.

That's exactly what I did for years.

Aftermarket shackles (in the upper most holes) and air shocks with extensions on the top.

I have been thinking about this for a while now. Re arcing brand new leaf springs seems expensive. Air shocks would require a shock absorber bar so that's probably more expensive. My son has a 95 Jeep CJ with a 2" lift kit. The leaf spring extenders are not like shackles with multiple holes for different heights, they are made to give you a 2" lift so they are hardly noticeable under the car, unlike shackles. Not sure if the Jeep lifters would fit on a tri five Chevy, but I'm sure you could find someone that could make some that would. Any way you raise the rearend is going to affect your handling, so if you are going for the retro look, would something like this work and be more affordable?

Mike, I made the upper shock bar that went under three '57s. Okay this is 1980s pricing but I had about $25 in each shock bar.

That upper shock bar Robert made for Dana's '55 Wagon is very simple to create.
1. piece of pipe long enough to stretch across the frame with a few inches so the pipe can be inserted in holes you drill in the frame rail with a hole saw.
2. two bolts. Possibly 1/2 x 3 inches long.

Once the pipe is in position under the body, determine where the upper bolts need to be in relation to the upper shock holes in the trunk. Remove the pipe. Drill the 2 needed holes for the bolts to pass through the pipe.

NOTE: if you have the bayonet stock type shocks for the rear, you will need to purchase two new shocks. These will have holes at both ends unlike the originals. As long as you the part number for the shocks you have, any parts store can cross reference them to a shock with mounting holes at each end.

That is a clever (and affordable!) way to create a shock bar. I'll have to remeber that when i need to change my rear shocks. However, you also have to buy the air shocks to get the 2" lift. When I get a chance I'll climb under my son's jeep to see how the 2" lifters fit. I imagine you could still use the stock shocks.

There was something said earlier about the common lift blocks not working on a stock tri-5 rear spring setup-has to do with the fact the springs are under the rear end housing.....guess that would LOWER a car whatever size blocks you put in??
So RJ-no fooling.....YOU HAVE 14x8 wheels and 24560x14 tires on the back of a stock suspension '57?? ours sure looks low for that big of a tire.....
And Guys BTW: I had to withdraw my order from Discount Tire-turns out that they couldn't produce the set of tires and wheels in time for my Wife's Birthday on April 29th, so I got them coming all mounted and ready to put on car from www.newstalgiawheel.com GREAT FOLKS THERE!!!

Here is my other Hardtop.
Rear wheels are 14x8. Backspacing is 4 inches.
Tires are 245/60/14, BFG T/A radials.
A couple differences in our cars.
1. Mine has 7 leaf, leaf springs.
2. Air shocks. Mine had 3 inch extensions on the top.
3. Rear shock bar installed.
4. It does have stock rear shackles.
In this photo there is 10 psi in the air shocks.
* Since this photo I've removed the shock extensions. The rear sets even lower.



My very first car.
Leaf springs are 5 leaf.
No shocks on the car at the time.
Shackles are stock.
Tires are 245/60/14.
Wheels are 14x8.
Backspacing is 4 inches.



New rear tires.
245/60/14, BFG T/A radials.

RJ, hey Thanks for the info AND PICTURES!! I love the "Dusk Pearl" color is it?? also love the stance of that car-I'd love to be able to have ours sit that high when I put the new wheels on it! I'd also love to lower it back down when we run the stock 750x14 wide whites and spinner wheel covers.
Damn it man-you stole my new tires!!-LOL!!
Cragars ARE the rim for '57s!! and I think the Radial TAs are a decent tire as well.

Thanks.
Yes it's Dusk Pearl.

I love the Cragar S/S wheels too. Always have. If I had the funds I'd invest in a set of 17 inch S/S wheels.
The T/A radials are a very nice tire. I love them. BUT. I do not want all my '57s looking exactly the same. When I research Tire Rack for tire sizes back in 2004 for the tires on my pink Hardtop, Tire Rack had listings that was 2 pages in a 245/60/14 tire.
Earlier this year when I researched their web site, they offer one (1) choice. The T/A radials.
Fourteen & fifteen inch wheels & tires appear to be out of production? That tire companies are selling off the stock they have, and THAT IS IT. So, future tires in those sizes (14 & 15) will have to come from places like Coker. And I know for a fact Coker is more expensive versus other sources.

If I could have located them, I would have tried a 255/50 or 255/60 tire instead of the 245/60s I did buy. To have a different look.

I also can't wait to have the new tires on my first car. Last time I bought "New" tires for the car was 1979.
