The Jeep Wrangler JL and JLU claim to be trail-ready right from the factory, but if you've ever been out on a trail crawling more than pebbles, you know that a stock set up isn't going to get you very far. If you want to conquer any obstacle that you come across, these top 10 Motobilt upgrades are a must. Built for strength, style, and serious off-road performance, here are the top 10 products we recommend most for JL/JLU owners who want to build the ultimate adventure rig.
1. Front Inner Fenders for 40" Tires (MB1243) & High Clearance Rear Inner Fenders (MB1254)

They open up maximum tire clearance and dramatically improve the appearance of your wheel wells. Their vented design boosts airflow and keeps things cool, while the precision fit gives your JL or JLU a finished, pro-built look.

7. Rubicon Diff Covers – Front (MB4075) & Rear (MB4073)

They not only protect your axles but also look killer doing it. If you plan on getting your Jeep into anything gnarly, these are a must.
