Our Camburg bump stop mounts bolt onto the rear of your 2007-2021 Toyota Tundra with ease. These are designed to use King 2.0 x 2" hydraulic bump stops (#BS2020) with Deaver K-37/U-748 spring-over leaf springs or the equivalent. They provide additional bottom out control to maximize the vehicles entire suspension travel. They are MIG welded, powder coated wrinkle black and include all the necessary Grade 8 hardware. These bolt into existing holes in the frame once the factory bump stop mounts are removed, so their is no guess work on placement or drilling needed.
