which 3 leaf set is the way to go?

Need some opinions...got info back from 5 suppliers, and need to see if anyone has any experience...or if one is definitely better to go with. Here is what we currently have:

We have a 1967 coupe and plan on adding the subframe connectors at the same time (already have the competition engineering bolt ons). The car won't be raced (although it won't be out of the question to get on it from time to time), but we are looking for a good combination of comfort and performance (the Camaro is a weekend driver)...hence the move from the 5 leaf currently installed and not a switch to the mono leaf (the previous owner had wanted to race it, so he put on the 5 leafs with CalTracs traction bars). We don't want to raise or lower the vehicle much past stock, and the front end appears to be stock height. From what I understand, the 3 leafs all raise the end about 1.5" over a new stock mono, and the Hotchkis lowers about 1.5" under stock...just not sure what I'm going to get. The attached pics are with the 5 leaf that have raised the rear end.

1) Classicmuscle.com, made by JR Springs -$200

2) SD Trucks.com, made by multiple sources including Eagle, JR Springs, or other US made (depending on inventory) -$200

3) Eaton, made by Eaton -$349

4) Spring Works (local shop), Triangle Springs -$451

5) Hotchkis, made by Hotchkis (2407c) -$459


I would rather buy the better of the five, but if all things are equal...I don't want to just pay extra if it doesn't benefit us in our situation.

Thank for the help

Re: which 3 leaf set is the way to go?

Dave, Your comments are bit confusing. "We don't want to raise or lower the vehicle much past stock, and the front end appears to be stock height. From what I understand, the 3 leafs all raise the end about 1.5" over a new stock mono, and the Hotchkis lowers about 1.5" under stock...just not sure what I'm going to get." If this is the case then scratch them from your list. What's left if you do? Experiment by removing a leaf or 2 from the five leaf. You may not need to purchase new springs.

Re: which 3 leaf set is the way to go?

What we need to know is....
1) what does it measure now ?
2) where do you want it to sit ?
3) what size tires now and/or planed on ?

I have the 4-leaf replacements and am 28.5" to the rear lip with 275/60/15's, stock replacement coils cut 1 full coil and 26" to the lip with 205/65/15 fronts.

Hope this helps some...

Re: which 3 leaf set is the way to go?

allanjs...
I guess I shouldn't try and mutli-task while I'm typing...I was confused by what I wrote. Here is more of what I meant...

When I spoke to the reps for the JR's, Eagle, Triangle, and Eaton springs...they all said that they were direct replacement OEM springs that would have the rear sit at a stock mono (in good condition) height. The problem was that no one could tell me what that height was so I could judge them. One of the reps from Eaton did say that the springs could possibly make the rear sit slightly higher then stock...but did not give a reason why. Hotchkis said that their leafs would definitely drop the rear 1.5" from the stock mono, but they were unable to give me a stock reference point either.

My problem is I don't know where stock is...and the previous owner could not remember where he got the 5 leaf springs for the rear or replacement springs for the front end. Between that, and not knowing how much they may have sagged...I'm kind of at a loss. I was looking at the Hotchkis by recommendation, but I don't know if that will put the rear lower than the front...if so, I wanted to see if anyone had experience to point me in the direction of a particular 3 leaf.

We were looking at switching out the 5 leafs, because it rides VERY stiff in the rear. The car is a weekend driver, and won't be taken to the track (what the previous owner put them on for).

Hopefully that is clear as mud.

DOUG G...

-from the ground to the bottom of the fender lip...rear is about 28 1/4" and the front is about 27 1/8" (attached the photos)

-the stance is fine as is, or with the rear slightly lower...just don't want the rear to sag below the front

-all four are 235/60/15s...no plans on a change right now


allanjs and DOUG G...thanks for the replies and help

The Hotchkis lowering springs do just that....lower the car.
All the other options will be "about" where you are now...I doubt the springs sagged much, if any, with the 5 leaf you have now.

I would say either the 3 or 4 leaf with a better shock (shocks make a world of difference).

Re: which 3 leaf set is the way to go?

FWIW, I recently replaced my mono's with the JR 3-leafs and also added some KYB gas shocks. The car now sits almost perfectly level and rides MUCH better. I also have the Hotchkis SFC's, which are a necessity in a convertible.

The front is stock with some new KYB shocks. Wheels are 14".

There are some pics of my car after the the spring change in this thread. Mine is the yellow convertible. There is also one in post 43 of this thread.

Dave, Factory heights can be found in the AIM. Here's a link to download them if you don't already have them.

For information on swapping to the 3-leaf setup, this thread is a must read.
