Got a car with a JF011E or RE0F10A CVT transmission (common in many Nissan, Mitsubishi, Dodge, Jeep, and other models from around 2007 and up) that's making noise or needs rebuilding? This is a replacement drive belt chain, which is the core internal belt that actually transfers power in your CVT. It's a brand new part designed to be compatible with OEM part numbers 901047 and 901066. This is a critical component, so it's built to strict quality standards and is 100% tested before shipping. A heads-up: Replacing this belt is NOT a simple DIY job. It requires completely disassembling the transmission, which should only be done by a professional mechanic or a very experienced builder. This listing is just for the belt chain itself (1 piece). BEFORE YOU BUY, this is super important: You MUST verify the exact part number you need by checking your old part or a reliable repair guide. Don't just go by vehicle model alone. If you're doing a CVT rebuild, this is the essential internal piece you'll need.
