Rear Leaf Spring Clamps

    Does anyone know of a source for the clamps that hold the spring sections together? ...the ones with the rubber inserts...I’m restoring the leaf springs on my SI V6 project and it would be easier/cheaper to just replace the clamps rather than having them re-plated or powder coated. I can only find the replacement rubber and not the clamps themselves in the usual parts catalogues.

    Bill, have you upgraded the spring hangers to s2 or later? If not might be worth doimg as rootes upgraded the rear leafs to wider spec after SI. With a v6 a little stronger lateral resistance is a good idea. Especially if you still run the lever arm dampers or will you convert to telescopic?

    Yes....I’m upgrading the suspension to SV both front and rear to an SV....including rear axle and shocks.

    Hi Bill (and Michael) just wanted to make sure you were aware of how Tom Hall dealt with the weak rear leaf forward spring mount. I did a version of this to the car I'm starting to drive harder and I was amazed at how wimpy the stock connection is.
    This can be done with a completed/painted car if you mind the heat.

    Yes we are reinforcing that and a number of other areas on the car as well.

    That is a very interesting article that I don't remember seeing before. The current price for the "forward rear spring mount reinforcement kit" appears to be $150 which is a bargain.

    First I've seen of this Article also.... May pay to look at your Alpine as well?

    I have looked at my S-V and there is no apparent damage. Not surprising with only 92.5 net HP and 103 ft.-lbs. of torque, but it was probably originally designed for a lot less and I intend to have considerably more. A little proactive reinforcement seems like a good idea.

    We’re getting a little off topic (I’m still looking for a source for the steel band clamps! ) but here’s a picture of the spring hanger on my SI. The rear floor has been removed so it’s much easier to see the connection to the x-frame or lack thereof...it looks surprisingly fragile although with the floor in place not quite as bad as it looks...but, as said, for less than 100 hp it’s probably OK. We need to widen the hanger bracket to accommodate the late series springs that will go on the car...we already had plans to strengthen that connection prior to this thread pop up. 859B0CCB-26AA-4162-A78E-1F6C8B9FAFD5.jpeg

    Bill, I've only ever seen people reuse the clamps, I've never seen repos.

    If some are too rusty to use call Smitty in San Diego 619 233 7937. Just let the phone ring.

    If you do find new ones please post the source.
