The Jeep Wrangler 4xe Extreme mounting system bolts to existing mounting points on the chassis and roll cage. This unobtrusive, high performance, nearly indestructible mounting solution allows you to quickly remove the Freedom Panels with the rack in place. The windscreen can also be lowered without any interference. The cargo weight is evenly distributed across the roll bars and body of the jeep, placing zero weight on the hard top itself.

All Front Runner Racks are backed by a Limited Lifetime Warranty*
