Timbren Industries FR1504E Rear Suspension Enhancement System Kit

The Timbren Industries FR1504E is a rear suspension enhancement system designed for 2015-present Ford F-150 trucks (both 2WD and 4WD models). This innovative kit replaces the factory bump stops with engineered Aeon hollow rubber springs that provide progressive load support up to 6,000 lbs capacity.

Key Features:

• Progressive spring rate technology - automatically adjusts to load conditions
• Zero maintenance design - no air lines, no pressure checks, no leaks
• Simple bolt-on installation in under 30 minutes with basic hand tools
• No drilling required - direct replacement for factory jounce stops
• Maintains factory ride height when unloaded
• Includes powder-coated steel mounting brackets and all necessary hardware
• Lifetime warranty coverage against defects in materials and workmanship

Performance Benefits:

• Eliminates rear-end sag when towing or hauling heavy loads
• Reduces trailer sway and improves roll stability
• Absorbs road shocks and automatically adjusts to uneven loads
• Maintains level ride whether loaded or unloaded
• Durable enough for off-road use

The FR1504E kit features precision laser-cut steel brackets with black powder-coated finish for long-lasting durability. The hollow rubber spring design provides a set-it-and-forget-it solution that requires no ongoing adjustments or maintenance. Note: This system increases spring rate but does not increase GVWR - always stay within manufacturer load ratings.
