This kit extends both of your axle breather hoses as well as your transfer case and transmission breathers, and ties them into the factory air box for a worry-free sealed system. A must have for anyone who plays in mud or does the occasional stream crossing. Works great in conjunction with a River Raider Snorkel System or as a stand alone kit. Installation takes about half an hour. Be the envy of your fellow Jeepers with your new extended hose! We have tested this setup and found our extended hose kit provides satisfying results! Now available for the new JT Gladiator and JL Wranglers 2018 and newer!
