2018-2025 Jeep JL Wrangler Engine/Underhood

Elevate the power, torque, capability, and utility of your Jeep Wrangler JL with our extensive range of engine and underhood upgrades. At Northridge4x4, we offer a comprehensive selection of enhancements for 2018-2025 Jeep JLs, designed to optimize performance both off-road and on pavement.

Our programmers deliver exceptional functionality, allowing you to recalibrate your JL's computer for larger tires or disable the auto start-stop feature and much more. Onboard air kits make inflating tires after a trail run quick and hassle-free, while our exhaust upgrades not only enhance your Wrangler’s sound but can also improve performance and, in some cases, increase departure angles.

To keep your JL running cool under pressure, we provide cooling system upgrades that regulate temperatures during low-speed crawling or towing. Whatever engine or underhood upgrades your Wrangler needs, Northridge4x4 has you covered!

Make sure you also take a look at our JL Drivetrain Upgrades, JL Lighting Upgrades, and our JL Exterior Upgrades to totally overhaul your Wrangler!
