CV4

CV4 has become a trusted name in the powersports industry for its advanced cooling system upgrades designed to withstand extreme riding conditions. Their silicone radiator hose kits are among the most popular performance upgrades, offering improved heat resistance, increased pressure tolerance and longer life compared to standard rubber hoses. Whether outfitting a motocross bike, trail machine or UTV, CV4 hoses deliver consistent coolant flow and help maintain optimal engine temperatures.

In addition to hose kits, CV4 produces high quality radiator caps, thermal barrier films, vent tubing, and fuel line sleeves, each engineered to handle heat, pressure and vibration common in competition and aggressive riding. Their radiator caps help increase the boiling point for better cooling efficiency, while thermal films protect fuel tanks, airboxes, and sensitive components from excessive heat. CV4 vent tubing and line sleeves add durability and protection for riders who push their machines through mud, dust and high temperature environments.

Every CV4 component reflects a focus on longevity, reliability and performance, making the brand a go to for riders looking to upgrade their cooling system or replace worn OEM parts. From trail riding to full throttle racing, CV4 products support improved engine performance and help prevent overheating issues, ensuring your machine stays protected mile after mile.
