Timbren SES (FRF53A) Suspension Enhancement System - Rear Axle Kit fits Select Ford F53 with Leaf Spring Front Suspension

This SES Suspension Upgrade replaces the jounce stop on the frame. Its unique design ensures superb ride quality loaded or unloaded. (There should be a to 1 gap between rubber spring and axle to ensure unloaded ride quality. If the van body is heavy, no clearance is necessary.) Unlike other auxiliary spring systems, the SES Suspension Upgrade guarantees the best of both worlds.

This kit is rated at 8600 lbs capacity. Even though youre increasing the spring rate by adding this upgrade, this does not increase the GVWR (Gross Vehicle Weight Rating). Please make sure that the load does not exceed the GVWR set by the manufacturer.
