The Rock Slide Engineering 300 Series Flat Tow Brackets (SKU FB-300-FTB) are the factory-frame-mounted safety chain attachment brackets for flat towing the 2018–2026 Jeep Wrangler JL and 2020–2026 Jeep Gladiator JT. 7-gauge (0.179-inch) steel construction. Brackets mount directly to the JL/JT factory frame — not to the bumper — ensuring safety chain loads transfer to the frame rather than through bumper mounting hardware. No drilling, no cutting. All installation hardware included. Estimated 1-hour install. 5 lbs per pair. Sold as a pair — driver and passenger side included.

These brackets are NOT compatible with Rock Slide Engineering Rigid Series bumpers. Verify your bumper compatibility before ordering.

Component Specifications

What Is and Is NOT Included

Why Frame Mount Matters for Flat Towing

Safety chains in a flat tow configuration are a secondary retention system — they must be capable of supporting the full weight of the towed vehicle in the event of coupler or hitch failure. Safety chain loads must transfer to the frame or a frame-mounted structure, not through the bumper shell or bumper mounting hardware. The 300 Series brackets mount directly to the JL/JT factory frame, which is the correct load path. The 7-gauge (0.179-inch) steel construction provides the yield strength required for safety chain attachment loads in this application.

Bumper Compatibility

These brackets mount to the factory frame independently of the bumper. However, Rock Slide Engineering Rigid Series bumpers are explicitly incompatible with this hardware. Confirm your bumper before ordering.

Critical Compatibility

Common Questions

Why must safety chains attach to the frame and not the bumper? Safety chains are a secondary retention system — in the event of coupler or hitch failure, they must hold the full weight of the towed vehicle. Bumper shells and bumper mounting hardware are not engineered for that load. Frame-mounted attachment ensures the safety chain load transfers directly to the vehicle's structural frame, which is the correct and legally required load path for flat tow safety chains in most jurisdictions.

Will these work with my Appalachian Series bumper? Yes — the 300 Series Flat Tow Brackets mount to the factory frame independently of the bumper. They are compatible with the Appalachian Series and 300 Series bumpers. They are NOT compatible with the Rigid Series. If you are unsure which Rock Slide Engineering bumper series you have, text (469) 407-7538 before ordering.

Do I need to drill into the frame? No. The brackets mount to the factory frame using the included hardware without drilling or cutting. All mounting hardware is included.

What safety chain rating do I need? Safety chains must be rated for the full gross weight of the towed vehicle — not just the tongue weight. Verify the chain working load limit against your JL or JT GVWR before purchasing chains. Chain rating requirements may also vary by state and by tow vehicle manufacturer guidelines.

The Obsidian Take

The 300 Series Flat Tow Brackets (FB-300-FTB) are for the JL or JT owner who flat tows behind a motorhome or tow vehicle and needs dedicated, frame-mounted safety chain attachment points. Five pounds, 7-gauge steel, 1-hour install, no drilling. The frame mount is the correct load path — bumper-mounted chains are not the right solution for flat tow safety chain loads.

One hard check before ordering: confirm you are not running a Rock Slide Engineering Rigid Series bumper. These brackets are explicitly incompatible with that series. If you are running an Appalachian or 300 Series bumper, or no Rock Slide bumper at all, these brackets install cleanly to the factory frame without modification.
