GM Chevy 4L80 Transmission Hose, 70in Stainless Steel Flexible with Adapters
Designed for GM Chevy 4L80 transmissions, this 70-inch stainless steel flexible transmission cooler hose with adapters delivers a robust, long-lasting solution for upgrading or replacing your cooler line. Constructed from 304 stainless steel for enhanced flexibility and durability, it handles the heat and vibration of daily driving and aggressive builds alike. With a 3/8-inch diameter and AN6 inverted flare ends, it provides reliable, leak-free connections and easier routing through tight engine bays.
Whether you’re refreshing a classic hot rod, upgrading a muscle car, or fabricating a custom ride, this hose set offers broad compatibility. It covers 700R4, 4L60, 4L60E, 4L65E, TH350, TH400, TH200, 200R4, and 4L80E (1996 and newer) transmissions, plus suitability as a replacement for Ford C4/C6 AOD, and can fit various Chevy trucks and cars. Some adapters are 1/4" NPT, expanding compatibility with a wide range of fittings. The included adapters simplify installation by reducing the need for additional parts and fittings, helping you finish the job faster and with fewer leaks.
One of the standout advantages is routing flexibility. The 70-inch length gives you generous reach across the engine bay, while the stainless steel construction resists corrosion and pressure fluctuations better than rubber hoses. This hose set is ideal for Rat Rods, Hot Rods, and Muscle Cars, offering a dependable upgrade that blends with vintage aesthetics while delivering modern durability.
