Lexus Rear 3" Extended Bump Stops GX470 (2003-2009)
3-Inch Extended Bump Stops for Lexus GX470 LT Shock Kits
Running 12-inch rear shocks on your 2003–2009 Lexus GX470? Your suspension setup demands a bump stop engineered to protect it. The DuroBumps DBR525LT is a 3-inch extended rear bump stop, purpose-built to meet the exact requirements of Dobinsons Spring & Suspension LT rear kits (shock part numbers ending in -575) and Apache Offroad’s AX2-30R 12” shock packages.
Both suspension kits require a 3-inch extended bump stop to properly limit suspension up-travel and prevent over-compression of longer shock bodies. That’s why DBR525LT exists—giving lifted GX470 builds the correct bump height to match their high-performance shocks.
⚠️ Critical Fitment Requirement:
To use DBR525LT safely and effectively, your GX470 must maintain a true 3-inch rear lift at ride height while fully packed with fuel, passengers, gear, and accessories. This ensures your extended shocks have enough stroke to manage suspension travel before the bump stops engage. Without this lift, early bump stop contact can cause harsh bottom-outs and unsafe handling.
If your build doesn’t meet these conditions, consider a different suspension kit that better matches your intended ride height and performance goals.
When installed correctly, DBR525LT delivers progressive bump zone engagement, bottom-out protection, and smoother suspension behavior—on the trail or on the road.
GX470 Suspension Upgrade: 3” Extended Rear Bump Stops for LT Kits
DBR525LT installs directly into the factory rear bump stop location on the 2003–2009 Lexus GX470—no cutting, welding, or adapters required. It is specifically engineered to meet the installation and performance needs of Dobinsons Spring & Suspension LT kits (shock part numbers ending in -575) and Apache Offroad’s AX2-30R 12” rear shock packages.
These performance suspension kits require a 3-inch bump stop to protect the longer shock body from over-compressing during full suspension compression. DBR525LT delivers that required 3-inch bump height—limiting up-travel to prevent damage to shocks internals under aggressive off-road use or heavy bottom-out conditions.
Because DBR525LT engages 3 inches earlier than OEM bump stops, your GX470 must have a true 3-inch rear lift at ride height while fully packed with passengers, fuel, cargo, and gear. This ensures the 12” shocks have adequate compression stroke to control axle movement before the bump stop makes contact. Without sufficient lift, the bump stop may engage too early, leading to a harsh ride and compromised vehicle stability.
When installed on properly equipped builds, DBR525LT delivers smoother bump zone behavior, protects critical rear suspension components, and improves driver comfort—on rocky trails, remote adventures, and daily commutes alike.
