Timbren FR250SDG Rear Suspension Enhancement System is a heavy-duty suspension upgrade designed to improve load stability, reduce rear-end sagging, and provide additional support for compatible Ford F-250 Super Duty pickup trucks.
Featuring patented Aeon hollow rubber springs and an 8,600 lb rated spring capacity, this rear suspension kit automatically responds to changing loads and road conditions. Its progressive design helps reduce excessive body roll, swaying, and suspension compression when towing trailers or transporting heavy cargo.
Unlike conventional air suspension systems, the Timbren FR250SDG requires no compressors, air lines, or pressure adjustments. Its durable construction and straightforward bolt-on installation provide dependable suspension assistance without complicated maintenance.

Advanced Aeon Rubber Spring Technology
The Timbren FR250SDG uses patented Aeon hollow rubber springs engineered to provide progressive suspension resistance as vehicle load increases.
Unlike conventional helper springs that may apply constant resistance, Timbren’s progressive rubber springs become firmer as additional weight compresses the suspension.
When the truck is unloaded, the springs are designed to maintain clearance from their contact points, allowing the factory suspension to operate normally.
As cargo weight increases, the rear suspension compresses and the Aeon rubber springs progressively engage to provide additional support.
This technology helps balance everyday driving comfort with the stability required for towing and hauling.
Improved Towing and Hauling Performance
Towing trailers or carrying heavy equipment can place considerable demands on a pickup truck’s rear suspension.
Excessive suspension compression may affect vehicle balance, handling characteristics, and driving comfort.
The Timbren FR250SDG provides supplemental suspension support to help manage these conditions.
-
Helps reduce excessive rear suspension sagging.
-
Improves resistance to body roll during cornering.
-
Helps minimize side-to-side swaying.
-
Provides additional support during trailer towing.
-
Helps maintain a more level vehicle stance.
-
Cushions certain road shocks and impacts.
-
Supports more controlled suspension movement under load.
The system works alongside the vehicle’s factory suspension rather than replacing the original leaf springs or shock absorbers.
Compatible Ford F-250 Super Duty Trucks
The Timbren FR250SDG is designed for rear suspension installation on compatible Ford F-250 Super Duty pickup trucks.
Ford F-250 Super Duty Compatibility

2011 Ford F-250 Super Duty
-
2012 Ford F-250 Super Duty
-
2013 Ford F-250 Super Duty
-
2014 Ford F-250 Super Duty

2016 Ford F-250 Super Duty
The kit is designed for specified two-wheel-drive and four-wheel-drive pickup configurations.
Important Fitment Information
Compatibility depends on the exact vehicle year, drivetrain, factory suspension configuration, and installed equipment.
This kit should not be assumed compatible with Ford F-350 or newer F-250 models simply because they belong to the Super Duty series.
Always verify the exact vehicle application using Timbren’s fitment information before purchasing or installing the kit.
Comfortable Ride When Unloaded
The Timbren FR250SDG is designed to provide additional suspension support primarily when the vehicle is carrying a load.
During unloaded driving, the rubber springs are intended to maintain approximately 1/2 to 1 1/2 inches of clearance from their axle contact points.
This allows the factory suspension to handle normal road conditions without constant engagement from the helper springs.
As cargo weight increases, the rear suspension compresses and the rubber springs progressively provide additional resistance.
This design helps balance everyday ride characteristics with the additional suspension support required during heavier hauling applications.
Maintenance-Free Suspension Performance
Unlike air helper spring systems, the Timbren FR250SDG operates without compressed air or electronic equipment.
-
No air compressor required
-
-
No manual pressure adjustments
-
-
No routine inflation or deflation
-
No electrical connections required
-
Automatic response to changing loads
Once properly installed, the system provides dependable supplemental rear suspension support without routine air pressure maintenance.
The simple mechanical design also reduces the number of components that require attention during regular vehicle use.
Easy Bolt-On Installation
The Timbren FR250SDG features vehicle-specific mounting brackets designed to use existing factory suspension mounting locations.
The kit replaces the original rear bump stops with Timbren Aeon rubber spring assemblies.
For compatible applications, installation generally requires basic hand tools and does not involve drilling or permanent modifications to the vehicle’s suspension.
The installation process involves removing the factory bump stops, assembling the Timbren springs and mounting brackets, and securing the assemblies using the supplied hardware.
Proper spring positioning and clearance must be checked according to the manufacturer’s installation instructions.

Important Load Capacity Information
The Timbren FR250SDG has an 8,600 lb rated spring capacity. This rating refers to the supplemental suspension system and does not represent the truck’s allowable payload or towing capacity.
Installing the kit does not increase the vehicle’s Gross Vehicle Weight Rating (GVWR), Gross Axle Weight Rating (GAWR), or manufacturer-approved towing limits.
All cargo, trailer tongue weight, and vehicle loads must remain within the manufacturer’s specified ratings.
The suspension enhancement system is designed to improve support and stability within the vehicle’s existing weight limitations.
Ideal for Work Trucks and Recreational Towing
The Timbren FR250SDG is suitable for compatible Ford F-250 Super Duty trucks used for everyday driving, cargo transportation, and towing.
