A Wrangler on factory underbody protection copes right up to the first serious rock crawl. After that you learn how thin the standard plates are, and that the muffler, tank and lower control arms sit exposed between them — precisely what a rock ledge finds.

This kit replaces that with six 6.0 mm aluminium plates. Rival lists engine, gearbox, muffler and fuel tank protection plus lower control arm skids for the front and rear axles.

6.0 mm aluminium. Silver finish, 6.0 mm thickness. At that gauge alloy gives resistance close to far heavier steel — and on a vehicle where every kilo under the frame shows up in suspension behaviour and fuel use, that is an argument in itself.

Important restriction. Rival states the kit is designed for vehicles with the standard front bumper. If you run a tubular or steel aftermarket bumper, check fitment before ordering. The technical note also refers to the two-door body.

Installation. Fitting kit included, mounting to the factory frame points.

Fitment. The catalogue name lists the Jeep Wrangler 2017-2021 and Jeep Gladiator from 2018 with 2.0 l and 3.6 l petrol engines. The manufacturer's technical description narrows this to the two-door Wrangler 2.0T and 3.6 from 2018-2021. Confirm your exact version with us before ordering.
