Inner Fenders | FR & RR | Vertex | Jeep Wrangler JK/Wrangler Unlimited (07-18)

Vertex Inner Fenders FR & RR for Jeep Wrangler JK/Wrangler Unlimited (07-18) deliver a clean, aggressive look while protecting your engine bay and critical components when you run aftermarket flares. Built to complement your JK’s suspension travel and tire clearance, these inner fenders are the smart upgrade you need for both durability and style.

Why choose Vertex Inner Fender Liners?

Designed to outpace stock liners, Vertex Inner Fenders combine rugged construction with practical protection. Here’s what sets them apart:

• Three-piece construction for maximum coverage: Each liner projectively shields more of the engine bay and surrounding body panels than typical liners, reducing mud, dust, and debris intrusion during aggressive off-roading.
• Corrosion-resistant powder coat: A durable finish stands up to mud, water, and road grime, preserving appearance and performance in tough environments.
• Solid-steel, angular design with distinct Vertex styling creates an aggressive, trail-ready face that integrates with aftermarket fenders and flares.
• Color-matching potential and customization: The front liner features a removable plate for color accents to pop against your paint, while the rear liner perfectly aligns to reveal the body color behind it.
• Secure, quiet mounting: Engineered to mount firmly to the body to eliminate rattling or vibration, even on rugged whoops and washboard roads.
• Bolt-on installation with minimal drilling: A straightforward upgrade that you can tackle in a home garage with common tools, keeping downtime to a minimum.
• Lifetime Replacement Warranty: Vertex backs these liners with a commitment to lasting performance, giving you confidence on every trail.

Protection that actually matters

When you remove stock fenders to gain clearance for bigger tires, you also lose vital protection. Vertex Inner Fenders seal off the most exposed areas from dust, mud spray, and debris kicked up by the front wheels and rear wheels alike. This keeps your coil packs, wiring, radiator, and other sensitive components cleaner, helping maintain engine efficiency and reducing the risk of corrosion or heat buildup over time.

Designed for Wrangler JK 2007–2018 with aftermarket flares

Specifically sized for the JK and Wrangler Unlimited chassis, these FR & RR liners are paired with aftermarket fenders to maximize clearance and articulation. The result is a cohesive, rugged exterior that protects critical paths while preserving the intended wheel travel and clearance you bought the flare for in the first place.

Who this is for

• Off-road enthusiasts running aftermarket flares and larger tires who want added protection without sacrificing access to the engine bay.
• Jeep owners who plan to tackle muddy trails, sandy washes, or desert runs and want to minimize debris intrusion.
• Competitors to stock liners who need a more comprehensive shield that covers additional surface area with a durable finish.

What you’ll get and how it helps you perform

• Enhanced engine bay protection reduces the risk of scrapes, mud buildup, and heat-related residue on vital components.
• A sportier under-hood appearance that matches the visual heft of upgraded fenders and flares.
• Improved longevity of body panels and fender liners due to robust steel construction and protective coating.
• Effortless upkeep—wipe clean after off-road days to maintain the pristine look and protective finish.

Installation tips and practical notes

Vertex Inner Fenders are designed for a bolt-on installation with minor drilling. Gather common tools, follow the included mounting points, and you’ll be enjoying improved protection in a weekend. Plan for a quick alignment check after the first drive to verify a snug, rattle-free fit and to confirm the front color plate sits as desired with your chosen paint or wrap.

How Vertex compares to other liners

Compared to standard liners, Vertex offers broader coverage, a tougher powder-coated finish, and a cohesive look that pairs with aftermarket fenders. The 3-piece configuration reduces gaps and shields areas that are most exposed when fenders are removed, delivering both practical protection and a more integrated, aggressive aesthetic without compromising articulation or clearance.

Warranty and support: Vertex backs these inner fenders with a lifetime replacement warranty, underscoring the brand’s confidence in their durability under real-world off-road use.
