Made in the USA.

Why Rear High Line Fenders Matter on the JK Platform

The Jeep Wrangler JK and JKU are proven platforms on technical terrain, but fitting larger tires correctly requires more than just adding lift. Rear tire clearance becomes a major limiting factor when running 40–42-inch tires, especially at full compression and articulation.

Running larger tires with factory rear fenders often requires excessive lift to keep the tire from contacting the body and flare area during suspension cycling. That extra lift raises the center of gravity, increases body roll, and reduces the stability that makes the JK and JKU so capable in the rocks.

Rear highline fenders change the math. By raising the rear wheel opening and creating more usable tire clearance, they allow larger tires to cycle farther into the wheel well with significantly less lift. This keeps the Jeep lower, more stable, and better balanced on technical terrain.

For JK and JKU owners who want to run 40-inch tires or larger while maintaining a lower center of gravity, rear highline fenders are one of the most effective upgrades available. They help the suspension work through its travel instead of being limited by fender contact.

Key Features

40"+ Tire Clearance
The raised rear wheel opening is designed for JK and JKU builds running 40-inch and larger tires. It helps reduce tire contact at full compression and articulation where factory rear fenders cannot provide enough clearance without excessive lift.

Run Bigger Tires with Less Lift
Rear highline fenders give larger tires the rear wheel well room they need with less lift than factory-fender builds require. Less lift means a lower center of gravity, better trail stability, improved handling, and a more capable Jeep both on and off the trail.

Improved Rear Suspension Up Travel
The highline rear wheel opening creates more usable up travel by allowing the tire to cycle higher into the rear wheel well without contacting the fender. This allows your suspension, shocks, and lift kit to work more effectively on technical terrain.

Lightweight Aluminum Construction
Built from aluminum for strength without unnecessary weight. Compared to steel fenders, aluminum keeps the Jeep lighter while offering corrosion resistance and trail-ready durability.

JK/JKU-Specific Fitment
Designed specifically for the 2007–2018 Jeep Wrangler JK 2-door and JKU 4-door. This is not a universal fender or adapted design. It is built specifically for the JK/JKU platform.

Bolt-On Factory Mounting Points
Installs using factory JK/JKU rear fender mounting locations. Some drilling required for Riv Nuts.

Clean, Aggressive Profile
The rear highline design gives the JK and JKU a more aggressive, purpose-built stance while improving real off-road performance. This is a functional clearance upgrade that also gives the Jeep a cleaner, more capable look.

Ships Raw Aluminum
Powder coat, paint, or leave raw to match your build. Raw aluminum does not rust and can be left natural for a clean off-road look.

Made in the USA
Designed and manufactured in America for the JK/JKU platform.

Rear High Line Fenders vs. More Lift

There are two common ways to make larger rear tires fit on a JK or JKU: add more lift or create more fender clearance. More lift can provide room, but it raises the Jeep’s center of gravity and can hurt stability on technical terrain.

Rear highline fenders solve the problem at the wheel opening instead of compensating with extra ride height. By increasing usable rear tire clearance, they allow larger tires to fit with less lift and better suspension function.

For builds running 40-inch tires or larger, this matters. The goal is not just making the tires fit in the driveway. The goal is making them fit at full compression, full articulation, and real trail use without compromising the Jeep’s handling and stability.

Best For

2007–2018 Jeep JK and JKU owners who want to run 40"+ tires with less lift than factory rear fenders require.

JK and JKU owners building around larger tires who want a clean, functional rear highline fender solution.

Daily-driven JKs and JKUs that also see trail use and need a rear fender upgrade that works both on-road and off-road.

Frequently Asked Questions

Does this fit both the 2-door JK and 4-door JKU?
Yes. The Savvy aluminum rear highline fenders fit 2007–2018 Jeep Wrangler JK 2-door and JKU 4-door models using factory rear fender mounting points.

What tire sizes do these accommodate?
They are designed for JK/JKU builds running 35–42-inch and larger tire setups, depending on lift height, wheel offset, bump stop setup, axle placement, and overall suspension configuration.

Do these require cutting the body or frame?
No frame cutting is required. These rear highline fenders are designed to install using factory JK/JKU rear fender mounting points with some drilling to install Riv Nuts.

Do these work with factory rear inner fenders?
For maximum clearance on larger tire builds, rear highline outer fenders should be paired with high-clearance rear inner fenders. Factory plastic liners or low-clearance inner fenders can become the limiting contact point at full compression.

Do I need matching front highline fenders?
For a complete highline setup and balanced appearance, we recommend pairing these rear fenders with the Savvy Offroad Aluminum Front Ultra High Line Fenders.

What finish do they ship in?
Raw aluminum. Powder coat or paint them to match your build, or leave them natural. Aluminum does not rust in raw condition.
