The 3.2s are just shocks. No other parts included.
You could install a bump stop spacer in conjunction with them which would give the truck the same travel specs as a 37 truck. Since the shocks are their own unit, you can’t use top hats with them. The Index bump stop spacers get installed between the stock rubber bump stop and the frame to increase the height of the bump stop. It makes the bump stop height identical to that of a 37 truck. Those you can install with the 3.2s because they are not part of the shock assembly. Hydraulic and pneumatic bump stop kits entirely replace the stock bump stops. The SVC ones are the only ones where you can choose between 37 or 35 bump stop height. To be honest, unless you’ve got weight in the bed, the gen 3 doesn’t really need bump stops in the rear. People would be really surprised how infrequently they bottom out the rear compared to the front.
