Fitment, Shipping & Product Support
The Rock Slide Engineering Appalachian Mid Front Bumper (SKU FB-F-310-JK) is the full steel front bumper for the 2007–2018 Jeep Wrangler JK. All-steel construction at 130 lbs — engineered for JK-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. Winch and recovery loads transfer through steel hardware throughout — no aluminum shell in the load path. Estimated 2-hour install on a stock JK. Sold as a single unit.
This is full steel construction at 130 lbs. For the aluminum-shell composite variant (73 lbs) or the stubby aluminum configuration (67 lbs), see the comparison table below.

Lighting Configuration
| Position | Type | Notes |
|---|---|---|
| Main shell — inboard | 2x 4-inch | Factory JK fog light position — retained in main shell |
| Wings — outboard | 2x 4-inch | Auxiliary light mounts on removable wings |

Critical Compatibility
| Configuration | Notes |
|---|---|
| Jeep Wrangler JL — 2018+ | Does not fit — JL frame mounting geometry differs from JK. See FB-F-310-JL. |
| Jeep Gladiator JT | Does not fit. See FB-F-310-JL for JL/JT fitment. |
| Winch compatibility | Verify your winch footprint matches the integrated winch plate bolt pattern before ordering. |
| Lifted builds with modified front-end components | At 130 lbs of additional front-end weight, confirm suspension and steering components are appropriate for the load. |
| Modified vehicles with aftermarket bumper mounts | Confirm factory frame mounting points are undamaged and in stock location. |
| Light bar larger than 20 inches | Bull bar accepts a 20-inch light bar maximum. |
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 most important pre-order confirmation step for any winch-capable bumper. Text (469) 407-7538 if you need help confirming.
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. If you want a stubby-only build from the start, the aluminum Appalachian Stubby (FB-S-300-JK, 67 lbs) is the lighter option.
Why choose full steel over the aluminum composite variant? Full steel means no aluminum in the load path — winch pulls and recovery forces transfer through steel hardware throughout. The aluminum composite variant uses an aluminum outer shell that reduces weight to 73 lbs, with steel handling the load-bearing components. For moderate to aggressive trail use where sustained impact loads are expected, full steel provides greater structural integrity. For a daily driver that sees occasional trail use, the aluminum composite saves 57 lbs.
At 130 lbs, what should I check before installing on a lifted JK? Confirm your front track bar, control arms, steering components, and front springs are rated for the additional front-end load. At 130 lbs, the impact on steering feel, handling, and suspension geometry is meaningful — particularly on builds with significant lift or modified front-end components. Professional installation is recommended for winch mounting and recovery point torque specifications.
The Obsidian Take
The Appalachian Mid Front Bumper (FB-F-310-JK) in steel is for the JK owner who wants maximum structural integrity — full steel construction, winch capable, dual recovery points, outboard lighting mounts, 130 lbs. The removable wings give you a stubby option without buying a second bumper. 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, evaluate suspension and steering component condition, especially on a lifted build. If weight reduction is the priority, the aluminum composite variant saves 57 lbs. If structural integrity under sustained trail loads is the priority, this is the correct bumper for your JK.
