Timbren spacer kit for 1999 Chevrolet Silverado/GMC Sierra 2500 adapts the Timbren SES rear helper springs when the frame-to-axle gap grows to about 8.75"–10.25" due to a lift. The kit supplies two 1-inch and two 1/2-inch spacers plus mounting hardware so you can configure the GMRCK25S SES assembly for the correct unloaded clearance, allowing the SES system to remain effective while hauling or towing with a lifted truck.
