Looking for options on rear shocks
I’ll start off with saying I’m new here. My father (LPS37) used to post here after he first got his 37 a few years ago and got a lot of help. I remember him talking about Shine(?) and Jims mothershead (I thinks those were some names of some guys that helped him out with things). Unfortunately my dad passed away unexpectedly 2 years ago...way too young. I’ve had dads 37 now for 2 years but haven’t had it in me to use it the way dad would have liked. I’m finally starting to use it more and want to keep up with what he started..and make a cpl improvements and changes to fit my style and taste.

It’s a 37 humpback. Well built car. My only complaint is the rear suspension. It bottoms out way too easily. It’s a leaf setup with bump stops, I think 1-9/16” bumps. Stance and ride height and gender gaps are all good, so I don’t have any sag I don’t think. Current shocks are Napa Response RR94038 (17.8 extended, 11.25 compressed). They appear to be universal type shocks. What other shocks are people using? I’m debating a set of QA1 double adjustable. Being able to adjust the compression would be huge, plus I can rebuild/revalve my own shocks if I don’t think there’s enough compression. I’m just not sure which part number is the correct one. The car weighs 3053 total. 1589 front 1463 rear.

I suppose ultimately converting to coil overs would be the right move. I’m just not sure how difficult that would be with the body on the car. Has anybody here done that and can give any insight?

Thanks

JM

  • Whoops..........Jim just read the "instructions". = other comments
    Dutch, aka Ken Fenical, aka Posie, makes great suspension with Thunderbird cup bushings.
    I met Dutch with his model A delivery in 1974 at Van Fest, Richmone Va.
    Dutch is a super rod builder.
    What is the length ? Some of the early rear springs were too short.

    Ditto with 36sedan & others.
    Back in the day many Ford buggy springs were replace with too-short trailer springs or Nova/Camaro rear springs.. Same car had a Corvair bolt in IFS,
    What springs do you have ?

  • Thanks for the follow up. It bugs me when guys ask for help and never let the responders know what ended up being the fix. Without a fix, we gain no knowledge, just read about the problem. Thanks, let us know what is next.

  • JMHO, but unless the shocks are bottoming out (wrong size)? Again JMHO, but I believe shocks are a dampening devise design to slow down bounce? While they can firm up a ride, I can't see them causing a bump condition if they're sized correct. But a simple and cheap test would be to remove the shocks and take it out for a short low speed test ride, if it still bumps, it ain't the shocks.

  • scooting.. sorry for the slow response, I was out of town for a bit.

    It actually has a posies parallel leaf setup in it. To be clear, this is a great handling extremely well built car that my dad had for 10 years and put probably at least 30,000 miles on it in that time. I just don’t like the the extremely hard hit when you cross something like a highway drainage pipe that’s sunk and gives that quick rear ended drop and slaps up on the bump springs. Maybe dad just tolerated it or hadn’t got around to finding a solution that he was happy with either. My note book shows he changed rear shocks and bump springs in the past cpl years. I’m guessing he was chasing the same thing as me.

    Right now the debate in my head is to put new springs on it from posies, replace the shocks with a set of double adjustable QA1s, which I can dyno and see what I have exactly and I can revalve those as needed if I think it needs a bigger compression stack, or possibly adding a bump rubber inside the existing bump spring.

    Ultimately in my head, shocks is the answer. They control the rate at which a spring works and I need to slow down the rate at which the springs are working.

    This will be a winter project so it’ll be another month or so before I get around to anything other than maybe shocks that I can do real quick.

  • Go online and look at Posie's. Then call them, let them know what you have and get the best ride ever.
