Maximize the effectiveness of your motor's cooling fan with a 1up Racing UltraLite Fan Shroud! Designed and Made in the USA by Vargr Industries with high quality materials and the latest 3D printing technology, our fan shrouds are strong while keeping the overall weight incredibly light. A perfect match for our 1up Racing UltraLite Aluminum Cooling Fans but are fully compatible and look great with any 4-hole 30mm or 40mm fans.
Traditional Ducted is the most common and directs all air forward. This is flat on the bottom for those who want to chassis mount their 1up UltraLite Cooling Fan without the Optional Brass Chassis Mount, but still fits perfectly along with our Brass Chassis Mount. 30mm size weighs only 2.7 grams, and just 4.1g in 40mm! |
