Timbren Industries

<h3>About Timbren Industries</h3><p>Timbren Industries is a privately held, family-owned company headquartered in Whitby, Ontario, Canada, with a story rooted in a single bold idea: that vehicle suspensions could — and should — work better. Founded in 1968 when entrepreneur Arnold Heron acquired the North American patent rights to a novel hollow rubber spring design known as &quot;Aeon,&quot; Timbren has spent more than 55 years turning that insight into a lineup of suspension upgrade products trusted by weekend haulers, fleet operators, and off-road enthusiasts alike. The company name itself is a nod to family roots — a combination of the names of Arnold's two children, Tim and Brenda.</p><h3>The Aeon® Rubber Spring Advantage</h3><p>At the heart of every Timbren product is the proprietary <strong>Aeon® hollow rubber spring</strong>. Unlike conventional steel leaf springs, which operate at a fixed linear rate, or air suspension systems that require ongoing pressure monitoring and maintenance, Aeon® springs feature a <strong>progressive spring rate</strong> — meaning they work harder as the load increases. The result is a suspension that stays calm and controlled under heavy towing or hauling, yet rides smoothly when the truck is empty. The self-damping properties of the rubber also act similarly to a shock absorber, cushioning road impacts without any additional components.</p><p>This &quot;install it and forget it&quot; philosophy is a key reason Timbren has earned a loyal following. There are no air lines to route, no pressure gauges to check, and no risk of a sudden air leak leaving you stranded with an unstable load on the highway. Every SES kit is engineered to bolt directly onto factory suspension mounting points, making most installations achievable in a driveway without specialty tools.</p><h3>Product Lineup: From Work Trucks to Off-Road Trails</h3><p>Timbren's flagship <strong>Suspension Enhancement System (SES)</strong> product line covers a vast range of vehicles — from compact SUVs to heavy-duty pickups and commercial rigs. The <a href="/13739-timbren-industries-suspension-rubber-helper-spring-kit-14989">Suspension Rubber Helper Spring Kits</a> represent the core of this lineup, replacing OEM bump stops with Aeon® springs that actively engage under load to level the vehicle, reduce squat, and improve towing stability. For trucks equipped with traditional leaf spring rear suspensions, Timbren's <a href="/13739-timbren-industries-leaf-helper-spring-15009">Leaf Helper Springs</a> integrate cleanly with the existing pack to add progressive-rate support without altering ride height when unloaded.</p><p>For drivers who prefer or already run an air suspension setup, Timbren's <a href="/13739-timbren-industries-air-suspension-helper-spring-15005">Air Suspension Helper Springs</a> can complement the existing system, providing a reliable rubber backup that adds stability regardless of air pressure fluctuations. Off-road enthusiasts will appreciate the <a href="/13739-timbren-industries-suspension-multi-purpose-bump-stop-15895">Suspension Multi Purpose Bump Stops</a> — Timbren's Active Off-Road Bumpstop line — which soften the bone-jarring jounce that occurs when a vehicle bottoms out on rough trails, keeping occupants comfortable and suspension components protected. Timbren also produces <a href="/13739-timbren-industries-coil-spring-support-10882">Coil Spring Support</a> solutions for vehicles with independent front and rear coil suspension setups, broadening their coverage across modern truck and SUV platforms.</p><h3>A Legacy Built on Innovation and Reliability</h3><p>Timbren's products have found their way onto everything from daily-driver pickups to Mack and Kenworth big rigs, a testament to the scalability and durability of the Aeon® design. The company backs every SES kit with a <strong>Lifetime Warranty</strong> and a 100-Day Satisfaction Guarantee, reflecting decades of confidence in the technology. Whether you are towing a fifth-wheel camper, hauling a contractor's payload, or navigating rocky back-country trails, Timbren Industries offers a suspension solution engineered for the real world — not just ideal road conditions.

Product Details

The Timbren Industries FRETRAHD SES (Suspension Enhancement System) is a heavy-duty rear suspension upgrade designed to eliminate sag, sway, and roll when towing and hauling. Featuring patented Aeon hollow rubber spring technology, this system provides progressive load support with an 8,600 lb capacity, automatically adjusting to changing loads without requiring any maintenance or adjustments.

Key Features:

  • 8,600 lb load capacity for heavy-duty towing and hauling applications
  • Patented Aeon hollow rubber springs provide progressive spring rates that increase resistance as load increases
  • Zero maintenance design—no air lines, fittings, compressors, or leak concerns unlike air bag systems
  • Maintains factory ride height when unloaded, engaging only when weight is applied
  • Simple bolt-on installation using included powder-coated steel mounting brackets—typically installs in under 30 minutes with basic hand tools
  • Self-damping rubber springs act like shock absorbers, providing superior ride quality loaded or unloaded
  • Cannot be punctured—hollow open-cell design eliminates air bag vulnerabilities
  • Backed by Timbren's lifetime warranty against defects in materials and workmanship

Unlike add-a-leaf springs that negatively affect unloaded ride quality, the FRETRAHD SES system only engages when weight compresses the suspension, ensuring your vehicle rides comfortably whether loaded or empty. The progressive spring rate technology provides increased stability and control, reducing dangerous suspension bottoming out on rough roads. Built from natural rubber and precision-engineered steel components, this system delivers reliable performance in extreme temperatures from sub-freezing winters to desert heat.

Note: This suspension enhancement system does not increase your vehicle's GVWR (Gross Vehicle Weight Rating). Always ensure loads do not exceed manufacturer specifications.
