Construction & Design:

Each hose in this kit is expertly crafted from five layers of high-grade silicone, reinforced with heat-resistant fibers to provide unmatched durability and flexibility.

The kit includes all necessary hardware, such as worm-gear clamps and a mounting bracket, to ensure a secure and proper fit. These hoses are engineered to fit precisely on 2018–2021 Jeep Wrangler JL and 2020–2022 Jeep Gladiator models equipped with the 3.6L V6 engine and automatic transmission, guaranteeing compatibility and ease of installation.
