FR750M – Rear Axle SES Suspension Upgrade

FR750M - Rear Axle SES Suspension Upgrade

This SES Suspension Upgrade can be adapted to fit the rear suspension of most heavy-duty Ford F600, F700 & F800 trucks equipped with leaf springs (see below for full list of applications). Each laser cut piece of steel is precision bent and powder-coated to ensure a quality fit. We’ve engineered our hollow rubber springs to deliver a progressive spring rate. In other words, the more weight that pushes down on the rubber springs the harder they work to prevent rear end sag, and help stabilize the load.



Product Features

  • Eliminate Vehicle Squatting & Sagging
  • Cushion Road Shocks
  • Improve Handling
  • Satisfaction Guarantee
  • Lifetime Warranty

Customer Reviews

"The Timbren system is the answer for rear end sag and soft handling! My 35ft 5th wheel handles much better, and I recommend Timbren without reservation."

- Larry V. - SD

“Timbren's work amazing! Absolutely as good or even better than air bags! Did it myself and only had time to drink 2 beer doing it! Easy install. Thanks for the advice. Simple yet very effective.”
