The TeraFlex Progressive Bump Stop Kit is a must-have suspension protection upgrade for lifted Jeep Gladiator JT builds, designed to absorb hard impacts and prevent damage when the suspension bottoms out. Unlike factory foam bump stops, these use closed-cell nitrogen-charged microcellular polyurethane, which compresses progressively—meaning soft initial contact, then firm resistance under heavy hits. This helps protect shocks, fenders, and axle components during aggressive off-road driving. They install directly into factory locations and are tuned specifically for 0–4.5" lift setups, making them a perfect pairing with lift kits, larger tires, and upgraded shocks. ✔ Progressive impact absorption (not harsh like factory stops)✔ Protects shocks, axles, and fenders from damage✔ Direct replacement for factory bump stops✔ Maintenance-free design✔ Built for off-road and high-speed use
