Convert to Multi-Leaf

Hey guys,


I see that there are multiple axle seat kits to support converting from mono leaf to multi leaf rear suspension. I have seen them on CPP, Jeggs, Summit. I believe Detroit Springs makes a bolt on kit, I don't know if the CPP kit is bolt on or if you have to cut the old perch out and weld in a new one. It seems that this is a common project but I don't see anyone recommending a specific kit. They all seem to be comparably priced, can anyone provide feedback on which kit they used and any fitment issues?


Thanks in advance!


Brady

Re: Convert to Multi-Leaf

I'm interested in this as well for my 67. However, some of the cars that I have seen converted over sit way too high in the rear. I want to retain my current ride height. Looking forward to hearing from some folks who have converted to the multi's, and how their car sits.

Re: Convert to Multi-Leaf

I installed the CPP lowering kit which included multi-leaf rear springs, shocks, front and rear sway bars, and new front coils. The advertisement said it would lower my car about 1.5 inches. No spring pocket mods necessary on my car, but, I have not been able to attach rear sway bar since my car still needs the additional weight of a fuel tank, interior etc. Other than the rear sway bar I like the kit for quality and ease of install. I would like the front of my car a bit lower, will have to see if springs relax a bit. BTW current wheel and tire combo is 15x8 rallys on the rear with 235 60R 15, front is 15x7 rally with 205 60R 15

What size tires are on your car? Yes, that is higher than my car sits, but like you said, they often "settle" a little lower once they are driven for a while.

This is how mine sits right now, and I would like to keep this stance:

I used the JCWhitney JRS 4-leaf replacement springs (not available from JCW anymore I believe) and made my own spacers....DIY easy

Re: Convert to Multi-Leaf

I did my 67 and used summit racing drop leaf springs and if I were to do it again I would also add 1.5 inch lowering blocks . I am hoping as others have said that it will settle lower after driving it a bit

Re: Convert to Multi-Leaf

I get mine from NPD and it does sit a bit high. Several I used get the same too high ride height and of course a rough ride to compound the issue. My mono car sits right and I can drink a coffee without spilling as the ride is a lot smoother. I have had to install lowering blocks 1 to 1.5" to get the ride height that is close to stock. They don't settle more than 1/2 inch. Good luck

5-way Rancho's and set on 5 at the track or 3 on the street


Can really feel a difference.


Would really like some DA shocks like Vikings

FWIW I used RideTech front lowering springs and the above^^^^^blocks in 2" using my stock single leaf. Speedway also has 2 degree shim blocks to use with these lowering blocks. What I did to keep my DL angle correct.

Dropped front 1 1/2" as advertised and back was 2".

The RideTech are progressive springs

Re: Convert to Multi-Leaf

Yes I believe those are the ones . I made some aluminum shims for the top where the bolt goes thru to hold the springs together and then added the spring perch extenders to block the springs in tight . It came out good

Thanks for the compliment, Tom! I like yours too - that is a great shade of blue and I like the old-school Cragars on the car!
