I am restoring a 1962 Chevy Impala, it now has a 283 cu. in. engine that I plan to replace with a 327 maybe 350. Anyway I just want to raise the back just a little so back is slightly higher then front . Any ideas? I am also planning on replacing back coils and I am working my way to the front and replacing front shocks and coils as well as other steering etc . Yes it mostly stock original stuff that needs tender care or replacing. Any ideas would be greatly appreciated. If we can agree on stuff I would gladly add you to my parts suplayinonbackerAug 12, 2021
Best Answer:Hello! This product would likely work to slightly lift the rear of your Impala, however, if you plan to replace the coil springs anyways, you may find coil springs that raise the rear without needing air shocks.

Will this lower the rear of my 64 impala? If so how low?Raymond R.Dec 27, 2024
Best Answer:Hi Raymond, I'm glad to assist you. No, it does not lower the height of the rear of your car. It maintains the factory standard height for the rear. Upon checking, we do not carry lowering shocks for the rear of your 1964 Chevy Impala.
