This UTV Extender Kit comes with 2 Louvers, 2 Duct Y-Fittings and total of 3’ - 6” (expanded) of 2″ Flexible Duct Hose to extend the air output capabilities of your direct-fit Inferno UTV cab heater. This kit is for customers who wish to add two extra louver locations on their front dash. OEMs do not run ducting to the rear seats on the crew cab so we do not recommend it either. NOTE (during winter season high demand): Heaters made per order, 5 to 15 business days handling time before carrier tracking number provided.
