I'm shopping for all new front and rear suspension for my 1970 CS that I'm building into a 442 clone (nice driver)........just looking for some suggestions on what brands are best.....aka moog, raybestes, acdelco, ect????? And also where to buy....looks like rock auto beats ebay?. I also want to go up instead of down, so back in the day, I remember hearing that if you put BB springs in front, it would add some lift? and station wagon in the rear it would do the same? Just don't want to mess up the ride, like I did 30 yrs ago with spacers in the front and air shocks in the rear LOL!!!! I don't want to afford $$$$ adj coil overs....figured I can do it with the right springs....also plan on several trunk loaded trips, so should I buy the progressive springs for the rear?
I'm also planning on adding a rear sway bar....OEM? Looking for a 1-2" level lift......not a jacked up hot rod
Thanks for your input!

My suggestion is to put in factory 442 springs as they should be 1" shorter ride height than the Cutlass Supreme springs.


My suggestion:
Moog 5536 up front
Moog 5409 in back

Buy Moog bushings, ball joints , tie rod ends, etc. from your local parts house, Rock Auto, or wherever has the best prices. It doesn't take long to shop around online.

Here's some front spring info from an old post:

Thanks Ken,
Well I bought all new suspension from rockauto....I got 5536 for front and cc503 for rear.....I hope I did right? I figure if it's to much for the rear? I can cut down?
Also got all new moog bushings and ball joints
