Savvy Offroad High Clearance Aluminum Rear Inner Fenders | 2018–2026 Jeep Wrangler JL / JLU

The Savvy Offroad High Clearance Aluminum Rear Inner Fenders are engineered for all 2018–2026 Jeep Wrangler JL and JLU builds but designed to give the clearance needed for running 35"– 42" tires and they solve a problem most rear inner fender designs completely ignore. In addition to providing maximum tire clearance and rear wheel well protection, Savvy's design includes additional coverage on the passenger side specifically to shield electrical wiring, fuel lines, and rear components from rocks, mud, and trail debris. At just 8.5 lbs per pair, they are among the lightest rear inner fender liners available for the JL platform delivering real protection without adding weight where you don't need it.

Compatible with stock fender flares and aftermarket high-clearance fenders. When you are ready to trim for maximum clearance on 40"+ builds, the inner fender panel itself acts as the trimming template no guesswork, no measuring, just a clean cut line that puts clearance exactly where your tires need it.

The Detail That Separates Savvy From Every Other Rear Inner Fender

Most high-clearance rear inner fenders focus entirely on tire clearance. They move the liner higher, open up the wheel well, and call it done. What they don't address is what lives on the passenger side of the JL and JLU rear wheel well electrical wiring harnesses, fuel vent lines, and rear component routing that runs directly through that space and is completely exposed once the factory plastic liner is removed.

Savvy's rear inner fender design extends coverage specifically to protect those components. If you wheel in mud, rocks, or heavy debris and the whole point of running 40-inch tires suggests you do this coverage is the difference between a trail upgrade that protects your Jeep and one that just clears your tires while leaving your wiring exposed to every rock that passes through the wheel well.

Key Features

• 35"– 42" Tire Clearance: High-clearance geometry eliminates tire rub at full compression, full droop on JL and JLU builds running 35 – 42 inch tires. Prevents the constant liner abrasion that destroys factory plastic on big-tire builds and allows full suspension articulation without contact.
• Passenger Side Electrical & Fuel Line Coverage: Savvy's design extends protection on the passenger side to shield electrical wiring harnesses, fuel lines, and rear components from rocks, mud, and trail debris coverage most competitors' rear inner fenders don't provide.
• Only 8.5 lbs Per Pair: 16-gauge CNC laser-cut aluminum keeps the complete pair at just 8.5 lbs. Lighter than most competing rear inner fender systems while maintaining the structural integrity needed for real off-road use.
• Acts as a Trimming Template: When you are ready to trim the rear body for maximum tire clearance, the inner fender panel itself serves as the cut guide. No measuring, no marking, no guesswork the panel shows you exactly where to cut for proper 40"+ fitment.
• Direct Bolt-On Installation: Mounts to factory JL and JLU mounting points. No drilling, no cutting, no modifications required for standard installation. All necessary mounting hardware included. Optional body trimming recommended for maximum clearance on 40"+ builds the inner fender acts as the template when you are ready for that step.
• Compatible with Stock and Aftermarket Flares: Works with factory fender flares, allowing you to upgrade your tires now and your fender setup later. Also compatible with aftermarket high-clearance fenders when you are ready to make that move.
• 16-Gauge CNC Laser-Cut Aluminum: Rust-proof, lightweight, and precision-cut using updated Jeep JL CAD data for exact fitment on 2-door JL and 4-door JLU models.
• Ships Raw Aluminum: Powder coat or paint to match your build. Raw aluminum can be prepped with Scotch-Brite and left natural. Note: some mill finish blemishes may be present on raw panels osmetic only, no effect on fitment or performance.
• Made in the USA: CNC laser-cut and precision-engineered in America using updated Jeep JL CAD models.

Rear vs. Front Inner Fenders, Do You Need Both?

On a JL or JLU running 35-40"+ tires with lifted suspension, the answer is almost always yes and here is why.

Front inner fenders handle tire clearance at the front wheel wells during steering and suspension compression the area most people address first because tire rubbing up front is immediately obvious. Rear inner fenders handle clearance during suspension articulation and compression at the rear axle, where tires stuff up into the wheel well on technical terrain.

Running front inner fenders without rear inner fenders on a 35-40"+ build means your front tires clear cleanly while your rear tires are still limited by factory plastic liners and your rear wiring and fuel lines remain unprotected. For a complete, properly built big-tire JL or JLU, both front and rear high-clearance inner fenders are part of the same upgrade.

See the Savvy High Clearance Aluminum Front Inner Fender Kit which includes both solid and vented panel options in one kit for the front wheel well solution that pairs with these rear fenders.

Best For

• 2018–2026 Jeep JL and JLU builds running 35”– 42" tires where factory rear liners are limiting clearance
• Lifted builds with increased rear suspension travel that has exceeded factory liner clearance
• Any JL or JLU build where rear wiring, fuel lines, and passenger side components need real trail protection
• Builders who want to upgrade tires now and trim for maximum clearance later using the liner as a template
• JL and JLU owners running stock flares who want to keep factory fender compatibility while upgrading tire size

Frequently Asked Questions

Do these fit both the 2-door JL and 4-door JLU?
Yes. The Savvy high clearance rear inner fenders fit all 2018–2026 Jeep Wrangler JL 2-door and JLU 4-door models using factory mounting points.

Do I need to trim anything for installation?
No trimming is required for standard bolt-on installation. For maximum clearance on 40"+ tire builds, optional body trimming is recommended and the inner fender panel itself serves as the trimming template, showing you exactly where to cut.

Will these work with my factory fender flares?
Yes. These rear inner fenders are compatible with factory stock fender flares. They also work with aftermarket high-clearance fenders when you are ready to make that upgrade.

What makes the passenger side coverage different from other brands?
Most rear inner fenders focus only on tire clearance and leave the passenger side rear wheel well partially open. Savvy's design extends additional coverage on the passenger side to protect electrical wiring harnesses, fuel lines, and rear components that run through that area. On a build that wheels in mud, rocks, or debris, this coverage protects components that are expensive and difficult to repair if damaged on the trail.

Do I need front inner fenders too?
On a 37”- 40"+ build with lifted suspension, yes. The front inner fenders handle clearance at the front wheels during steering and compression the rear inner fenders handle clearance during rear axle articulation and compression. Running one without the other leaves half your wheel wells unprotected. See the Savvy High Clearance Aluminum Front Inner Fender Kit for the front solution it includes both solid and vented panel options in one kit.

What tires sizes does this support?
Designed and tested for 35"– 42" tires on lifted JL and JLU builds.

What finish does it ship in?
Raw aluminum. Powder coat or paint to your preferred color, or prep with Scotch-Brite and leave natural or DA sand for a cleaner consistent finish. Some mill finish blemishes may be present on raw panels cosmetic only and normal for raw aluminum.
