🧾 Overview
The Grimm OffRoad ARB Brushless Twin Compressor Mounting Bracket Kit provides a complete engine-bay mounting solution for installing an ARB Brushless Twin Air Compressor on Jeep Wrangler JL/JLU and Gladiator JT models. The precision-cut steel mounting brackets position the compressor underneath the hood, behind the driver-side inner fender liner and beneath the brake booster.
The integrated design relocates the compressor's air intake filters to the upper engine compartment while positioning the control panel and air access near the driver-side front fender. An included aluminum heat shield helps protect the compressor from engine heat while keeping operating noise outside the passenger cabin.
Designed specifically for the ARB Brushless Twin Compressor, this kit also accommodates the previous-generation ARB Twin Compressor, making it a versatile mounting solution for Jeep owners upgrading their onboard air systems.
