This kit was all I needed to service my RZR 800. There was enough fluid for the transmission, transfer case, rear gear case and front gear case, and engine oil. It also has an OEM oil filter and OEM air filter, a spark plug set and an engine oil drain plug washer. All fluids and OEM parts. Compared to aftermarket fluids the cost savings of buying this kit is so small, why not use OEM? Will buy again if needed!
