Rock Slide Engineering Appalachian Mid Front Bumper | Winch Plate | Full Steel | 2018-2026 Wrangler JL & Gladiator JT | SKU FB-F-310-JL

The Rock Slide Engineering Appalachian Mid Front Bumper (SKU FB-F-310-JL) is the full steel front bumper for the 2018–2026 Jeep Wrangler JL and 2020–2026 Jeep Gladiator JT. All-steel construction at 130 lbs — engineered for JL/JT-specific mounting geometry. Integrated winch plate, dual D-ring recovery points, two 4-inch factory-position fog light pockets, removable wings with 4-inch auxiliary light mounts, and a removable bull bar accepting a 20-inch light bar. Estimated 2-hour install on a stock JL or JT. Sold as a single unit.

This is full steel construction at 130 lbs. If you are on a JK platform or need the aluminum-shell composite variant, see FB-F-310-JK (JK, 73 lbs).

Component Specifications

What Is and Is NOT Included

Full Steel vs. Aluminum Composite — Why It Matters

The JL/JT Appalachian (FB-F-310-JL) is full steel at 130 lbs. The JK Appalachian (FB-F-310-JK) uses an aluminum outer shell with steel inner structure at 73 lbs. The 57-lb difference reflects full steel construction, which provides greater structural integrity for moderate to aggressive trail use, sustained rock contact, and recovery operations.

The JL/JT platform's front suspension and steering geometry handle the additional front-end weight of a steel bumper, but the impact on front-end handling, steering feel, and suspension geometry should be evaluated — particularly on lifted builds or builds with modified front-end components. At 130 lbs of additional front-end weight, suspension and steering component condition matters before installation.

Lighting Configuration

All three lighting positions are independent. Wings can be removed for a stubby profile while retaining main shell fog light pockets, winch plate, and D-ring mounts.

Critical Compatibility

Common Questions

How do I confirm my winch is compatible? Check your winch's bolt pattern against the Rock Slide Engineering integrated winch plate specification before ordering. Winch bolt patterns vary by manufacturer and model — this is the single most important pre-order verification step for winch-capable bumpers. Text (469) 407-7538 if you need help confirming before purchase.

Can I run this in a stubby configuration? Yes. Remove the wings for a stubby profile. The main shell retains the winch plate, D-ring mounts, and factory fog light pockets when the wings are off. The bull bar is independently removable as well. Both can be removed or installed without affecting each other.

At 130 lbs, what should I check before installing on a lifted JL? Front-end weight affects steering feel, handling, and suspension geometry — particularly on lifted builds where front-end components are already operating at modified angles. Confirm your front track bar, control arms, steering components, and front springs are rated for the additional load. Professional installation is recommended for winch mounting and recovery point torque specifications.

Why is this 130 lbs when the JK version is only 73 lbs? Full steel construction vs. aluminum-shell composite. The JK Appalachian (FB-F-310-JK) uses an aluminum outer shell with steel inner structure and steel load-bearing components, totaling 73 lbs. The JL/JT version is full steel throughout — 57 lbs heavier but with greater structural integrity for moderate to aggressive trail use and sustained impact loads.

The Obsidian Take

The Appalachian Mid Front Bumper (FB-F-310-JL) is for the JL or JT owner who wants a platform-specific full steel bumper with winch capability, dual recovery points, configurable wing and lighting options, and the structural integrity of all-steel construction for moderate to aggressive trail use. Removable wings give you stubby-or-full-width flexibility. Three independent lighting positions cover factory fog, outboard auxiliary, and 20-inch light bar capability.

Two things to confirm before ordering. First — verify your winch bolt pattern against the integrated winch plate. Second — at 130 lbs of front-end weight, evaluate your suspension and steering components before installing on a significantly lifted build. Outside those two, this bumper covers everything a serious JL or JT trail build needs from the front.
