The 4.5” Extreme-Duty suspension system transforms the YJ into a superhero
able to climb tall obstacles in a single bound, all due to the well-tuned spring
packs. The Extreme-Duty kit is the most viable spring-under lift available,
offering ample clearance, a great ride, flexibility, and will clear 33x12.50”
sneakers. If you’re looking to clear 35x12.50-inch tires, we recommend adding a
1-inch body lift.
