Newly released, TBM Racing in conjunction with Joey’s Watercraft developed this simple yet effective head kit. Frustrated with constantly breaking domes on the “other” brands we were running we decided to build our own with our patent pending “Dome Saver” design. The head body and cap is constructed of 6061 aluminum, while the domes are machined from 7075, which is much more durable and rarely used due to it’s high cost. This head utilizes a three-piece design that has water flow control not possible with a one-piece head. No gaskets or messy silicone needed as it’s completely sealed by o-rings. Other key features are an integrated rear pipe mount for the Factory Pipe and a girdle design that eliminates the need to machine your cylinder. Truly a bolt on part with all necessary hardware and instructions included. Domes Sold Each

Non-Girdled Head has all the features of our Girdled Head without the added expense and complexities of the girdle kit. Cost effective yet high quality you can add to the reliability of your SX-R and have the option of running different compression ratios by interchanging domes. Recommended for use with the stock pipe, or Factory Wet Pipe this head is a great performer at a reasonable price. Domes Sold Each
