Stop Bottom-Outs and Tire Rub Before They Happen

Running extended-length rear shocks on your 4th Gen 4Runner? Then you need bump stops designed to match. DuroBumps DBR425 is a 2-inch extended rear bump stop engineered to prevent your longer shocks from bottoming out during full suspension compression—protecting your suspension, shocks, and chassis from harsh impacts.

Whether you're running 35s, 33s, or factory-sized tires, DBR425 is built for serious off-road rigs with a true 2" or greater suspension lift under full load. This means your ride height must still reflect a 2" lift even when fully loaded with passengers, gear, and fuel. If your suspension squats below that, this bump stop isn't the right fit.

As a bonus, the added bump stop height helps reduce or eliminate tire rub on the inner wheel well during heavy articulation—allowing your 4Runner to stay on line instead of backing out of a trail obstacle due to interference.

Suspension Synergy: Shocks + Bump Stops Working Together

DBR425 is designed to complement a properly dialed suspension system. It requires a true 2 inches of rear lift under full load—meaning your 4Runner should still sit at least 2" above stock height when fully packed with fuel, passengers, and gear.

Why is that important? Because your shocks and bump stops are meant to work together. The shocks manage most of the up-travel energy, while the bump stops are there to finish the job smoothly at full compression. Without enough lift, the bump stops may engage too early, limiting shock performance and affecting ride quality.

Whether or not you run extended shocks, DBR425 works best when paired with the correct spring rate and lift height to support your vehicle’s load. It’s a performance-focused upgrade that enhances suspension control and reduces tire rub when running tire sizes up to 35 inches.

Confidence You Can Feel. Performance You Can Trust.

Features

2-Inch Extended Profile
DBR425 is purpose-built to be 2 inches taller than stock, reducing up-travel by 2 inches to accommodate larger tires and prevent extended-length shocks from bottoming out during full compression.
Progressive Rubber Compression
Crafted from dual durometer rubber that compresses like a coil spring—offering soft initial contact and firm, controlled resistance at full compression.
Direct Bolt-On Installation
Installs easily in the factory bump stop location using OEM hardware points. No cutting, spacers, shims, or custom tools needed. All mounting hardware required is provided.
Optimized for Larger Tires + Lifted Setups
Specifically tuned for vehicles running 34–35" tires and a true 2" rear suspension lift under full load. Helps maintain tire clearance and prevent interference under full compression.
Precision Fit for the 4th Gen 4Runner
Designed exclusively for 2003–2009 Toyota 4Runner rear suspension. No spacers, no guesswork—just a clean, direct-fit upgrade for high-clearance trail builds.
Made in the USA. Always Will Be.
Proudly manufactured in Arizona using American-sourced materials and precision-molded tooling. No outsourcing—just high-quality craftsmanship built to last.

Benefits

Protects Extended Length Shocks from Bottoming Out
DBR425 reduces up-travel by 2 inches to prevent longer shocks from over-compressing and bottoming out—a critical safeguard for lifted setups using extended-length rear shocks.
Supports 34–35" Tire Fitment on Lifted Builds
By limiting upward wheel travel, DBR425 helps reduce inner wheel well contact—allowing larger tires to cycle more cleanly through articulation on the trail. (Proper wheel offset required.)
Improves Rear Suspension Control Off-Road
Whether you're flexed out on the trail or bombing across desert terrain, DBR425 enhances rear-end stability and comfort by smoothing out full-compression hits—effectively adding 1,500 lbs of spring rate during the final stage of suspension up-travel.
Built for 2"+ Lifted 4Runners Under Load
Specifically engineered for vehicles with a true 2-inch rear lift or more under full load. Works best when paired with extended-length shocks and the correct rear spring rate to support added weight from gear, fuel, and passengers.
Keeps You Moving When Trails Get Tight
By preventing the rear tires from making hard contact with the inner wheel well during full compression and heavy articulation, DBR425 helps you stay on your chosen line—instead of being forced to reposition mid-trail.
Essential for Extended Shocks + Larger Tires
If you’ve already upgraded to extended rear shocks and upsized to 34–35" tires, DBR425 is the bump stop designed to match. It’s the final suspension upgrade that keeps your lifted 4Runner performing as intended—delivering better clearance, smoother compression, and more predictable trail behavior where it counts.
