This Rear Bump Stop Kit for 2022-2025 Toyota Tundra, 2023-2025 Toyota Sequoia, and 2024-2025 Lexus GX550 provides improved performance over the OE bump stops with an easy bolt-on installation. The micro-cellular foam material is more compliant than the hard, stock rubber material and will help to soften bottom-outs when the suspension reaches full compression. The progressive bump stop design keeps the bump stop compliant to avoid jarring impacts on smaller bumps yet ramps up on harder bottom outs to absorb more energy, further improving suspension performance and ride quality.
