Coil overs
Which one are the best for stock frame pockets. I have global west upper and lower control arms. I was thinking QA1 but I here the shock gives a poor ride. Not saying what I heard is accurate, this is why I’m asking.
thanks
thanks

What I had before was original and completely shot.
I'm presently rebuilding my 70' Coupe with a SB. The coil spring Doug of GW recommended was I believe a 400 Lb medium ride not soft I think the length is a 9" & 1 1/8" sway bar ). No road time yet. But it's not that big a deal to swap out for a softer/firmer ride if need be.
The coil spring really depends on what type of driving and Big block or Small Block and front sway bar along with how you have the rear suspension set up.
Doug at GW is very knowledgeable and I really feel he set me up right. He'll set you up straight I think too.
Good luck with it.

We all know how and where the front shock upper mount is, With the OEM coil spring set-up the load is dispersed where the spring contacts the frame. To my knowledge the coil over suspension uses the same upper mount as the OEM shock, hence the load is now being dispersed in a much smaller area that was designed for just a dampening load, stressing 40 to 50 year old steel. Just a thought. T

No, the kits still use the frame spring pocket. Its the lower part of the shock that holds the spring and the shock connects to the lower A Arm.

So with that many choices I'm not sure how you could end up with a poor ride?

I contacted Global West and they were quite helpful, They are going to set me up with another manufacture of coil overs with the special spring for what I need. I am also contacting ride tech, just want to do the job right and not twice.

That special spring is probably not what you want. I don't know what spring you have now, but let's say that it is a 460# and you have driven around with it for a period of time. so you can make the best educated guess as to whether you need more spring or less spring.

I think he means a conical style spring. Its height is about 9" inches, not standard which won't work.9HTSP4503.80" I.D. Tapered High Travel Spring - 9" length4503.82.5DPigtail9**$79.95https://www.qa1.net/suspension/springs/front-pro-coil-shock-system-springs
