Jeep Wrangler JL and JLU owners, this TeraFlex bump stop shim kit is essential if you're running larger tires or have lifted your ride! These 0.5-inch shims extend your factory bump stops to prevent tire rubbing during hard compression and off-road articulation. The kit includes four front and four rear shims that are super easy to install - no fancy tools required. They're designed to work with TeraFlex's 2-inch bump stop strike pad extension kit (sold separately) to fine-tune your setup perfectly. Depending on your fender type and tire size, you might need different combinations - Sport and Sahara fenders typically need more bump stop than Rubicon models. For example, with 35-inch tires on Sport/Sahara fenders, you'd want 3-inch front and 2.5-inch rear extensions plus these shims. The shims help soak up energy and protect your suspension components from damage when you're really flexing out on the trails. Whether you're running 35s, 37s, or even bigger with aftermarket high-clearance fenders, proper bump stop setup is crucial for preventing expensive damage. This TeraFlex kit gives you that extra precision adjustment to dial in your suspension perfectly for your specific setup!
