Are you stock now? What shocks do you have?
There's some devil's magic involved with the front. Whatever the lift is for spacer, it's halved. Haven't really thought of if it's just one side or it's the increase weight on the driver side or if it's just general for lifts that range between x"and x". So always good to see if it's actual lift or actual size of the spacer. Depending on material it could compress. But they should be dense enough that compression is minimal. Compressing would lead to degradation and for it wear/rot away. Always prefer aluminum over rubber/polymer for lifts. Seeing that it has an opening, I'm guessing you can stretch it open to install. You can see in a lot of trucks where the spring isolator/insulator gets compress so much it dries out over time and cracks. Which to me it seems like it deteriorates and pieces fall out over time.
IMHO, coil spacers are a no go for me. Shocks only have so much space to compress the spring. So when you add a coil spacer, your adding outward force to the shock. Without enough weight/constant pressure, it can lead to premature failure. I feel it's harder to estimate what the lift will end up being taking into consideration how much the spring you have on there is compressed which would change ride quality. It would be harsh ride where coil spacers are installed. This will make it very stiff, absorb less and limit travel movement. Could be over pressurized and also lead to early failure. Just a bad idea all around.
From your build thread...
I would go Bilstein 5100's, OME Spring and AAL at the minimum. Can't recommend that enough for small lifts. Always avoid Rough Country. I'll post over there.
