Description
Improved Hauling Capability. Simpler than air bags and just as strong, a Timbren Rear Axle Suspension Enhancement System (SES) is an easy way to eliminate any suspension sag and squatting on 2015-2026 Ford F-150s. When unloaded, the SES sits off the axle and does affect ride quality. Once the F-150 is loaded with a trailer or something in the bed, the SES activates and engages with the rear axle, pushing up and leveling the truck. The SES also reduces trailer sway and body roll, making it not only ideal for those hauling heavy loads in the bed, but for F-150s that do a lot of towing as well.
Rugged Aeon Rubber. All Timbren SES kits use a special hollow spring made of Areon rubber. Engineered with a variable spring rate, the Arean springs progressively increase their resistance to compression as more weight is put on them and are self-dampening to eliminate annoying oscillations. The Areon springs are also maintenance free – once installed they can be forgotten about as there are no air bags to refill or air lines to leak. Backed by a lifetime warranty, Timbren’s motto is “stronger than steel, more reliable than air”.
Do-It-Yourself Installation. Upgrading the rear axle of your F-150 with a Timbren Suspension Enhancement Kit is easily done at home using traditional hand tools. Designed to be a drop-in process, the job can be completed in an hour with no modification necessary.
Application. This rear Timbren Suspension Enhancement System is designed to be used on all 2015-2026 Ford F-150s, excluding Raptor models.
