View Full Version : Ride height on repro leaf springs

I'm thinking about replacing my rear springs with the 4 leafs from D&R Classic, I think Tamraz on the internet sells the same springs. They are made by JRS. Does anyone have any info on what ride height these springs have or has anybody heard of JRS? The 4 leafs are about $160.00 vs. the 5 leafs at $120.00. Why would the 4 leafs be more expensive, are they a heavy duty spring?

I have 215/65 15 wheels and am looking for about 27" from the ground to the bottom lip of the wheel well. The distance from the top of the axle tube to the bottom of the frame would be 5 1/2 to 6 inches.

I replaced the mono-springs in my '68'vert with 5-leaf springs.
I think they sit too high, but was told they'd settle down..
.....I'm still waiting..

..as another TC Member once said, "put some mudders under that 4x4 'vert"..
no, it's not a 4x4, but I am looking for bigger tires in back.

That really looks to be way to high. Even with 20" wheels. I put 18 inch wheels on, And also went from mono to 4 leaf. I dought they will settle down. good luck.

Ghost, you can't be serious. They aren't gonna settle 7 inches in the rear.

A couple of things here..

It looks like the car is stripped so I figure it is NOT at it's finished or use weight!

Next, did you tighten everything down while it was up in the air so that all the bushings are too tight and actually helping to hold it up??

I'd finish the car as well as loosen it all up first before I would make a ride height judgement here b/c it probably will settle more than it looks now...

Can you guys give me some info on ride height? What type and manufacturer of leaf spring are you using and what height do get between the ground and the bottom lip of the wheel well?. Thanks

Oh ya, forgot to mention the car is a 69 Z28. Thanks again

Usually, this dimension is from the axle center to the lip, due to different sizes of wheels and tires selected by the owners.

Good point, I assumed 15" with correct tires. That eliminates a big variable. Thanks

I just measured my 69z28. It has new moog 3208 coils and eaton z28 4 leaf springs purchased from ricks. all suspension bushins are new, for that matte so is the entire suspension. It measures 26 inches in front and 253/4 in back with 3/4 tank of gas and the spare tire in the trunk. Ir is an all steel car and has iron heads. Forgot to mention 215/65/15 bfg on front and 235 /60/15 bfg drag radials on back that are about 60% spent. I don't notice any difference with 215/65/15's on the rear.

Thanks Dave. My car sits about 1" higher in the front, probably because I'm running aluminum heads. Would I be correct in saying with the 215/65 15 tires on the rear your tire tops are even with the lip? With mine being higher in the front, the rear will probably sit a little lower than yours with the Eaton springs. I wonder what the Eaton 5 leafs would give me?

I installed the JRS 4 leaf rear springs on my 67 last year. From the center of the wheel to the fender lip is 15¾ inches. I like them. Here are some pictures: 8.5 install (http://geocities.com/sdampier@sbcglobal.net/Team_Camaro/Rear)

Steve, did you use 68 multileaf plates and shocks?

Steve, did you use 68 multileaf plates and shocks?I used a reproduction 1968 multi leaf RH shock plate on the passenger side. A local steel shop made a custom LH shock plate for me as the 1968 LH shock plate won’t fit and no LH multi leaf shock plates were available for the 67 Camaro. The shocks are 1968 multi leaf.

I should have waited a few more months because Detroit Speed and Engineering (http://www.detroitspeed.com/Home10.html) came out with custom multi leaf shock plates for all first generation Camaros including 1967’s. I saw the new plates at their display at the Goodguys show and they look real nice.

One thing I don’t understand is why they don’t have the new Camaro shock plates listed on their website. :confused: The shock plates they have listed under products/rear suspension are not for Camaros.

Stock are fine imho!!

I say this b/c the same plate on the '68/'69's should work fine on both sides!

I't's only the '67's like mine that have a right and a left plate b/c the shocks are mounted the same and not staggered on both sides like the '68/'69 cars

I dont think the Detroit speed plates fit stock rear spring mounts. Ricks sells them and they only fit adustable spring mounts.

Are the multileaf shocks longer than mono? I have the Hotchkis springs and it seems the mono shocks are to short. I have shock extenders But I dont like them. Can I use Multi Shocks with stock plates?

These are DSE multi plates for 68-69 Camaros. They also make a LH multi plate for 67’s. I saw the 67 LH plate at the DSE display Goodguys a couple of months ago. Anyone looking for multi leaf shockplates for a 67 should give them a call.

Hey Steve, thanks for the wheel to fender measurement. I think the 67-68 wheel lip is higher than the 69. If possible, could you measure from the top of the axle tube straight up to the frame? This should be the same on 67-69, I think? Thanks, John

Steve, those plates must be new because they aren't on the website.

Steve,

I'm thinking of swapping out my mono leaf on my 68 for multi leaf. If I go with the 4 leaf, can I use the perchs on the car or do i need new ones?

My tires are slightly below the fender lip in the back (215's) as I remeber it. When I was trying to level ot the car I noticed when it went up in the front it went down in the rear and so on. I think the 5 leafs will probably be higher, since the z28 springs are supposed to be 1 inch lower than the other springs. My springs actually came from ricks but had eaton labels on them.

Here is a 69 with new Eaton 5 leafs and 15" BFG's in back and 14" in front. With full gas tank and full trunk on trips, it still slightly higher in back :)

Thanks for the pic Jim. Those rear tires look bigger than 215/65/15. If it's not too much trouble can you give me a measurement from the center of the cap to the bottom lip of the quarter? Thanks

Based on the measurements from Dave and Jim it appears that there is only about a 1/4" difference in height from the Eaton 4 leafs to the 5 leafs. The 5 leafs being slightly higher. Was the 4 leaf spring put in Z28s so the rear end would squat on launch, or is it stiffer to reduce wheel hop? What was the point of the 4 leaf vs. 5 leaf? Surely it wasn't just to reduce the stance or weight.
