Timbren Suspension Enhancement System for 2022-2025 Toyota Tundra. These replace the original bump stops on your truck and help with heavier loads or while towing. They keep the suspension from sagging as much. They're a very easy install (3 bolts on each side). These have been used for less than 1 year and are in excellent shape. Brand new they are $270.
