Savvy Offroad Aluminum Ultra Highline Fender Kit | 2018–2026 Jeep Wrangler JL/JLU

Transform your Jeep’s tire clearance and suspension performance with the complete Savvy Offroad Aluminum Ultra Highline Fender Kit for the 2018–2026 Jeep Wrangler JL and JLU. This complete kit combines Savvy’s front and rear aluminum ultra-highline fenders, creating increased tire clearance, matched styling, and improved suspension up travel at all four corners. Designed for Jeep owners building around 40–42-inch tires, the raised wheel openings create additional space for the tires to move during suspension compression, steering, and articulation. This helps properly configured JL and JLU builds run larger tires without relying on excessive suspension lift solely for tire clearance. Keeping the Jeep lower helps maintain a lower center of gravity, improves stability on steep and off-camber terrain, and allows the suspension to use more of its available travel before the tires contact the outer fenders. Constructed from lightweight, corrosion-resistant 5052 aluminum, these Jeep Wrangler highline fenders deliver trail-ready durability without the unnecessary weight and corrosion concerns of comparable steel fenders. Whether your JL or JLU is being built for rock crawling, trail riding, overlanding, competition, or aggressive street-and-trail use, the Savvy Offroad Ultra Highline Fender Kit provides the clearance, strength, and purpose-built appearance required for a serious large-tire build. Made in the USA and shipped in raw aluminum.

Why Ultra Highline Fenders Matter on the JL Platform

Fitting 40–42-inch tires correctly requires more than enough clearance while the Jeep is parked. The tires also need room during suspension compression, articulation, and full steering lock. Factory-style fenders can become a limiting point as the suspension cycles. Adding additional suspension lift may create space, but it also raises the Jeep’s center of gravity and can affect stability, steering geometry, driveline angles, handling, and suspension performance. Ultra-highline fenders address clearance directly at the wheel openings. The raised front and rear openings allow the tires to travel farther into the wheel wells before contacting the outer fenders. This allows a properly configured JL or JLU to maintain a lower, more stable stance while gaining additional tire clearance and usable suspension travel.

Actual clearance depends on the complete build, including:

• Actual tire diameter
• Wheel width and offset
• Axle width and position
• Steering angle
• Suspension height and travel
• Bump-stop configuration
• Front and rear inner-fender clearance
• Aftermarket steering and suspension components

Key Features

Complete Front and Rear Ultra Highline Fender Kit

Includes matched front and rear aluminum fenders for improved clearance and consistent styling at all four corners.

Designed for 40–42-Inch Tire Builds

The raised front and rear wheel openings provide increased clearance for properly configured Jeep JL and JLU builds running 40–42-inch tires. Final clearance depends on the complete suspension, axle, wheel, tire, inner-fender, and bump-stop configuration.

Run Larger Tires with Less Lift

Ultra-highline fenders create additional space at the body, reducing the need to add excessive suspension lift solely to prevent tire-to-fender contact. Less unnecessary lift helps preserve a lower center of gravity and better stability on steep, off-camber, and technical terrain.

Improved Front and Rear Suspension Up Travel

The raised wheel openings allow the tires to cycle farther into the wheel wells before contacting the outer fenders. This helps the suspension, shocks, and bump stops work through more of their intended travel.

Increased Front Steering Clearance

The highline front-fender design creates additional room for oversized front tires during steering and suspension compression. Actual full-lock clearance depends on wheel offset, axle width, steering angle, tire dimensions, and suspension configuration.

Lightweight 5052 Aluminum

Constructed from lightweight, corrosion-resistant 5052 aluminum for trail-ready strength without the unnecessary weight of comparable steel fenders.

Corrosion Resistant

Aluminum will not develop the rust associated with unfinished, scratched, or damaged steel fenders.

JL/JLU-Specific Design

Engineered specifically for the 2018–2026 Jeep Wrangler JL and JLU platform not a universal or adapted fender kit.

Clean, Purpose-Built Profile

The ultra-highline design gives the Jeep an aggressive, functional appearance that complements serious rock crawlers, trail rigs, and custom builds.

Ultra Highline Fenders vs. More Lift

There are three common ways to gain clearance for larger Jeep tires: additional suspension lift, modifying the factory fenders, or installing purpose-built ultra-highline fenders.

Additional Suspension Lift

More lift may create space between the tires and body, but it also raises the Jeep’s center of gravity. Excessive lift can affect stability, handling, driveline angles, steering geometry, and suspension performance.

Factory Fender Chop

A factory fender-chop kit removes or relocates part of the factory flare and lighting assembly. This can provide useful clearance for moderate builds, but it remains limited by the factory fender structure and wheel-opening geometry.

Ultra Highline Fenders

Ultra-highline fenders change the position and shape of the wheel openings. This creates additional vertical clearance and allows the tires to move farther into the wheel wells before contacting the outer fenders.

For properly configured 40–42-inch tire builds, this can provide more functional clearance while allowing the Jeep to maintain a lower and more stable stance.

The objective is not simply to make the tires fit in the driveway. They must also clear during suspension compression, articulation, and steering on the trail.

Frequently Asked Questions

Does this fit both the two-door JL and four-door JLU?

This kit is intended for 2018–2026 Jeep Wrangler JL and JLU models. 

Does this fit the Jeep Gladiator JT?

No. The front fenders may share platform similarities, but the JT uses a separate pickup bed and different rear wheel-opening geometry. A complete JL/JLU kit will not fit a Gladiator.

What tire sizes will this kit accommodate?

The kit is designed to provide clearance for properly configured 40–42-inch tire builds. Actual clearance depends on suspension height and travel, bump stops, wheel offset, axle width, axle position, steering angle, inner fenders, and actual tire dimensions.

Will 42-inch tires be completely rub-free?

No single fender kit can guarantee rub-free clearance on every vehicle. The suspension, bump stops, axles, wheels, tires, steering, and inner fenders must all be properly configured.

Can I run less suspension lift?

The raised wheel openings may allow a properly configured Jeep to run larger tires with less lift than factory-style fenders require. The minimum lift needed depends on the complete vehicle setup.

Is body or frame cutting required?

No frame cutting should be required. Drilling and rivet-nut installation is required for rear fenders. 

Do these work with the factory hood?

Yes. The Savvy front ultra-highline fenders are designed to work with the factory Jeep JL/JLU hood.

Are matching inner fenders required?

High-clearance inner fenders are strongly recommended for maximum usable clearance. The outer fenders enlarge the exterior wheel openings, but factory liners or low-clearance inner fenders can remain a contact point during full suspension compression.

What finish do the fenders have?

The fenders ship in raw aluminum. They can be powder coated, painted, or left natural. Raw aluminum will not rust, although normal surface oxidation and cosmetic changes can occur.

Are the fenders made in the USA?

Yes. The Savvy Offroad Aluminum Ultra Highline Fender Kit is designed and manufactured in the USA.
