Timbren SES Spacer Kit for 2015 Ford F-150 adapts the Timbren helper springs to lifted trucks by reducing excess frame-to-axle space. The kit includes two 1 in. and two 1/2 in. spacers and all necessary hardware, and is designed to work with PN FR1504E. It allows adjustable ride-height tuning up to about 10.5 in. so the SES rear kit remains effective for towing and hauling on lifted pickups.
