Timbren spacer kit for the 2017 Ford F-250 Super Duty Platinum SES adapts the Timbren SES rear helper springs when a suspension or body lift increases the frame-to-axle gap to roughly 7.75"–9.25". The pack includes two 1-inch and two 1/2-inch spacers plus hardware to adjust ride height with the FR250SDJ SES assembly, restoring load-carrying support for lifted trucks and backed by Timbren's stated lifetime warranty.
