Timbren Active Off-Road Rear Bumpstop Kit | 2024+ Tacoma, 2022+ Tundra & LC 250

Whether you are crawling through technical rock gardens or carrying full overlanding gear down washboard forest service roads, your vehicle's factory rear bumpstops are a notorious weak link. The rigid, OEM-installed hard rubber blocks provide almost zero compression zone. When your rear suspension bottoms out, that impact energy transfers instantly into the frame as a jarring, metal-on-metal slam that causes driver fatigue and strains your chassis.

The Timbren Active Off-Road Rear Bumpstop Kit replaces those unforgiving factory components with a progressive, maintenance-free rubber spring system. Engineered precisely for modern high-travel architectures like the 4th Gen Tacoma and 3rd Gen Tundra, these natural rubber bumpstops absorb and dissipate heavy rear axle impacts smoothly, keeping your vehicle controlled and your tires planted over unpredictable terrain.

Key Features

• Progressive Aeon® Rubber Springs: Unlike solid factory rubber or stiff aftermarket polyurethane, these hollow natural rubber springs compress in stages. The further your suspension cycles into its up-travel, the higher the resistance becomes, completely eliminating harsh bottom-outs.
• Heavy-Duty Load Absorption: Boasting a 4,800 lb peak bump load capacity, this kit handles high-speed trail G-outs and sudden drops safely, protecting sensitive shock shafts and rear frame mounts from structural deformation.
• Maintenance-Free Alternative: Delivers the smooth, energy-absorbing characteristics of hydraulic or pneumatic bumpstops without the high entry costs, complex mounting fabrication, or frequent nitrogen recharging and seal rebuilds.
• Chassis-Specific Plate Mounts: Pre-assembled on application-specific steel brackets designed to line up perfectly with your vehicle's factory axle strike locations, avoiding generic slip-on fitments.

What’s Included

• 2 x Patented Aeon® Hollow Rubber Springs
• 2 x Heavy-Duty Laser-Cut Steel Brackets
• 2 x Structural Steel Cups
• All Required High-Tensile Mounting Hardware

Pro Tip: If you are running an aftermarket multi-rate spring pack, a heavy rear bumper, or a permanent bedside kitchen loadout, your suspension is cycling through completely different weight thresholds than a stock truck. Upgrading to these progressive bumpstops ensures that even when your rig is fully loaded for a multi-day trip, your suspension transitions smoothly into its final inches of travel instead of aggressively kicking the rear end over trail ruts.
