Lexus GX460 3” Rear Bump Stops for Dobinsons & Apache LT Kits
Running Dobinsons Spring and Suspension or Apache Offroad LT rear suspension? Then your Lexus GX460 build demands a bump stop designed specifically to match. The DuroBumps DBR525LT is a 3-inch extended rear bump stop developed for 12-inch shock kits from Dobinsons Spring & Suspension (shock part numbers ending in -575) and Apache Offroad’s AX2-30R.
Both rear suspension kits require a 3-inch extended bump stop to limit suspension up-travel and prevent over-compression of the longer 12” shocks. That’s why DBR525LT exists—to provide the correct bump zone control and protect your upgraded shocks under aggressive driving and full suspension compression.
⚠️ Critical Fitment Requirement
To use DBR525LT safely, your GX460 must maintain a true 3-inch rear lift at ride height while fully loaded with passengers, gear, fuel, and accessories. This ensures the longer shock body has enough stroke to slow axle movement before the bump stop engages. Without the correct lift height, the bump stop will engage too early—leading to a harsh ride and unsafe handling during bottom-out conditions.
When properly installed on a GX460 running Dobinsons or Apache Offroad 12” shocks, DuroBumps DBR525LT brings smoother bump zone performance, improved ride quality, and critical shock protection—on every surface from daily commutes to technical trails.
Rear Bump Stop Solution for Dobinsons & Apache GX460 Builds
The DBR525LT bump stop is engineered as a direct-fit upgrade for the rear suspension of the 2010–2023 Lexus GX460—designed to bolt into the factory location without the need for spacers, trimming, or fabrication. It was developed exclusively to match the performance demands of 12” rear shocks included in Dobinsons Spring & Suspension LT kits (part numbers ending in -575) and Apache Offroad AX2-30R shock systems.
Both of these extended-travel shock kits require a 3-inch bump stop to limit suspension up-travel and prevent damaging over-compression. The DBR525LT provides this added height, allowing your GX460 to maintain proper bump zone timing, reduce hard bottom-outs, and protects shocks under heavy articulation and full bottom out conditions.
Due to the increased height, this bump stop engages sooner than stock. Your GX460 must have a verified 3-inch rear lift at ride height with full load—gear, fuel, passengers, and cargo included—to ensure correct function and safe suspension behavior. Using it without the required lift can cause premature contact and poor ride quality.
