Can you use any coil spacers for a 2nd gen rear spring with Downey 1.5" lift springs?

 

I think you can. Im not 100% sure but im guessing yes.

 

You can. I know that the 4Crawler spacers, I'm not sure on other brands, are not specifically built for the coils, they're just extensions from the top mount for the coil. The bottom of the spacers matches the the top mount. You'll probably want to get the panhard and LSPV brackets though. The lift will need them now.

 

If you think of the spacers as a "shim", you'll firgure it out.
