Eaton provides the assembled unpainted spring and liners. End cups are provided and are NOT assembled......Four Differential mounting bolts, spring end bolts by you......

NCRS Technical Manual says the metal leaf springs were coated with Ionoklad gray finish. Would you know anything about that and if so where to you get the gray coating.
Thanks

I use the leaf spring paint and liners Quanta sells. You'll need a special tool, or access to a press (or big vise) to install the spring cushion cups. I find that using the rounded end of a large ball peen hammer to get the flange of the cushion cups started and then finishing with some flat steel stock works well. There are many other ways to do it I suppose, but this is the way I have done it for years (ball peen and press).

have recently acquired the advertised tool that was designed for this job and it works well also.

The end cups can be installed (peened over) with Ball Peen Hammer securing the lowest (Long Leaf) on a Vise anvil.....Otherwise thoyer is correct.... That is the toughest part.

Others just insert the cup when attaching the spring to the outside bolts (No Peening). They are not going anywhere......... JMHO!

Also, Tom has a good option for paint. The Eaton liners that are included are equal to or maybe from Quanta..... They look to be Identical...

Good Luck!

Doug

Great info, why do the liners need to be changed if you have to take the spring apart anyway, can't u just use the same liners?
Thanks

They don't. I was just adding some additional info as I just went through a rear spring for the 66 I'm working on and the first set of liners I got from one vendor were not correct. I tried the Quanta's and they fit perfectly. If you get an Eaton spring they come with liners - no need to replace unless for some odd reason one gets damaged when you take it apart and reassemble it after painting.

Default rear composite spring package

Hello everyone, I am new to the group.

I have a 67 Convertible and want to freshen up the rear suspension. New Shocks, New composite rear spring , bushings etc then move to the front. I put a composite spring in my 75, 30 years ago and remember it was an imporvement. Has anyone done the complete kit avail from Corvette centrl or Ecklers? 315 lb or 340Lb?

I am wondering what you thought . Mine sits low and is a pretty choppy ride. Id like better handling a little bit and more comfy ride.

Thanks in advance

Gary

Read up on Avon tires and good adjustable shocks. With everything else up to spec the car should handle better then most have driving skill
and I would only buy t-shirts from that vendor

Default C2 Rear Leaf Replacement

Hello; I "recently" purchased my non numbers matching 65 Conv Corvette small block and went out to replace one brake caliper, but a few days later I had the whole car down to the bare frame!! I'm putting it back together now and am struggling to correctly install my brand new Eaton rear 9 leaf springs into my new Global West offset trailing arms. The leaves are rubbing up against my 60 series tires and wheel rims per the photos attached. I have tried the stock length bolt and the pictured 8 inch bolts without luck. You can also see the bolts are not straight down and leaning towards the tire as if the lowest leaf is too long for the car.
Can anyone direct me to my mistake or do I need to switch over to a single fiberglass composite leaf?
Thank you,
John

Most using 2" offset trailing arms use a shorten spring (generally a composite) and/or 17"/18" wheels. The larger wheel allows the ends of the spring to clear (fit slightly inside) the wheel rim. Vansteel has shorten composite springs. Note: spring rate increases as the length is shorten.

Opps! Left off the part about most are using wider wheels with more offset than stock to accommodate a wider tire which moves the rim and side wall further in towards the frame. Vansteel has a wheel/tire size guide on their site for their offset trailing arms; for C2 it's an 8" rim w/5" back spacing and 9" rim w/5.5" back spacing. Not familiar with Global West offset trailing arms and wheel/tire fitment.

Thank you and I will definitely check with Global to see if they have advice.
