These spacers mount on top of your rear coil springs between the rubber isolator and the chassis (1 per side) to raise the vehicle approximately 1/4", 1/2", 3/4" or even 1.00".
This spring spacer method is most commonly needed when people use a lowering drag spring in search of a stiffer spring rate - but need to raise the car for better tire clearance and alignment characteristics.
