Jeep Wrangler JL 4 Door (2018-Current) Extreme Slimline II 1/2 Roof Rack Kit - by Front Runner

This Slimline II 1/2 rack kit contains all the components needed to mount the Slimline II cargo carrying rack to a Jeep JL 4 door including the Slimline II tray (1425mm x 1358mm), the Jeep Extreme Mounting System and a Wind Deflector. Drilling is required for installation.

The JL 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 Rack Kits contain installation instructions as well as all the components and hardware needed to mount the Slimline II Tray to your vehicle.

These Foot Rails allow for a Front Runner under rack mount table (1 smaller Pro Stainless Steel Prep Table Kit or 1 larger Pro Stainless Steel Camp Table Kit) to be fitted.

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

For further information on installation, please see the fitment instructions in the INSTALL tab.

If your Slimline II Roof Rack kit uses Legs, add the height of the Slimline II Tray (50mm/ 2") to the height of the Legs to determine the height of the rack from your vehicle’s rain gutters.

If your Slimline II Roof Rack kit uses Foot Rails, add the height of the Slimline II Tray (50mm/ 2") to the height of the Foot Rails to determine the height of the rack from the crown (highest point) of the vehicles roof.
