JL Skid Plates
The Jeep Wrangler JL brings many upgrades over the best-selling 2007 - 2018 JK, but also has it's own unique undercarriage short-comings. It lacks any skid plates! A selling feature of the JL is also a hint at a major flaw: the suspension capabilities and increase fender flare clearance require less lift to increase tire size. This means wheelers can install larger tires and tackle tougher trails without having to install a traditional suspension lift kit. Less lift means more dragging your undercarriage and drivetrain all over the rocks.

Belly-Pan Design
To help you make it to the end of the trail, we're offering our most comprehensive and largest skid plate system we've ever designed. This is a true "belly pan" system that protects all your vital drivetrain components. The new JL 8-speed transmission drives fantastic, but is very long and pushes your drivetrain further back underneath your rig. To protect your transmission and transfer case, we had to increase the size of our skid plates. This is where our "belly pan" design gets to work. From frame rail to frame rail and oil pan to exhaust resonator, our design is comprehensive and complete.

Dual Crossmembers
Jeep had a brilliant idea to make the JL frame rails out of a new harder material, but trail testing has exposed a major flaw: thinner walls but stronger material twists! Early in 2018's Easter Jeep Safari exposed major flexing and twisting in rigs coming back off their day's runs. To prevent this plus strengthen our larger skid plates, we include 2 new 1" by 2" thick steel crossmembers. These CNC machined crossmembers extend from driver to passenger side frame rails and not only give our skid plates the foundation they need to protect your drivetrain, but also take twist and flex out of your frame.

Do I experience any driveline vibration or noise?
No. Our oil pan / transmission / dual cat skid mounts away from all driveline components giving you factory like performance. You'd never know the skid was even installed!

Do I have to remove or replace my factory cross member with an aftermarket one to install this skid plate?

This is a bit of a mixed review. I LOVE the RH4x4 products and the fact they are American made! I have bought the front bumper, full belly skid, FAD skid, muffler skid, and control arm skids. I have installed all of these myself just suing jack stands. I like that there are videos for the installs, most of which are very helpful. I very strongly dislike the provided written instructions. With the full belly skid system the instructions were frequently unclear and the included pictures are a GREAT addition, unfortunately they are all black and white and for the most part not useful. The pictures need to be in color with better lighting. This will go a long way towards clarifying the written instructions and reduce a lot of frustration. All in all, I am EXTREMELY happy with the product and the level of support I received when I called in! I plan to test everything in MOAB in June :)

A really nice, robust system.  Quality components, beautiful powder coat.  Install was very straightforward, easy even, by myself flat on my garage floor (aluminum probably helps).   I liked that it fit my Rubicon without other mods or messing with the gas tank, e.g. like Artec.

The online install video was especially helpful even if not entirely consistent with what I actually received, the photos helped too.

I had a couple squawks, tho tech support did clear up my questions.  First, the parts received didn't exactly match the parts list in the instructions, e.g. I have two brackets left over, apparently for a different model. Second, video, website photos, and instructions were not entirely consistent with each other about how the skids and cross-members fit together.  Maybe I'm just conservative, I like clear instructions to make absolutely sure I know what I'm doing before I get started.

Despite squawks, I'm very pleased.  I just ordered front and muffler skid plates.
