Second guessing suspension purchase

Shocks stop springs from doing springy things. Springs hold the weight up. Yes, you will get rid of the blocks with a better spring pack.

I have spacers/blocks. They do an adequate job, just adequate. With a topper, the rear sucks.

 

yes, in fact you should get rid of blocks in the rear

 

Yes, you could get rid of those blocks. Just to help you...... A {coilover} is the shock and the spring put together as one unit. The spring is what gives you the lift. The leaf springs in the back are what give you the lift.
Spacers and blocks can actually damage suspension components and the ride is much harsher.

 

No. 5160’s for the rear. (With 6112 up front)
