Bump Stops for a Timbren Rear Suspension Kit on a Lifted 2020 Chevy Silverado 1500

Question:

I have a 2020 silverado 1500 rst I put 2.5 in lift in the front with bilstein 5100 struts and roughly 2 inches in the rear with an add a leaf and bilstein 5100 2-3in over stock shocks. When I purchased the shocks they recommended I put in taller bump stops for the shocks being longer to prevent damage to the shock. I was wondering if I put these bump stops in if that would be enough or if I would need spacers?

The best way to determine how many spacers you need for the Timbren Suspension Kit item # TGMRCK15S, for your 2020 Chevy Silverado 1500, is to measure the distance from the underside of your frame where your bump stop sits to the axle directly below where the spring makes contact. The spring and bracket in this kit measure 5 inches tall unloaded and the spring should sit about 1 inch above your axle once it is installed with no load in the truck. From here, measure the frame to axle distance (unloaded) and subtract 6 inches (the height of the spring plus 1 inch gap) and the difference is how many spacers you need. Timbren offers a 1/2" spacer, item # TA25722-90F00 and a 1" spacer, item # TA25723-90AD00, that are compatible with this kit.
