New Copyrighted Gear box by DAX. Works great for 4 stroke in frame kits and other kits that need 5cm or 2 inch offset. After thousands of miles testing, it is now ready for sale. No longer does any one need to dish out hundreds of dollars for a decent gear box. This gear box is a take off of the pocket bike gear boxes that have been used and raced for many years. It has been changed or modified to fit our 4 stroke in frame kits. The beauty of this gear box is that it uses existing technology which makes it affordable. Since it is a 3:1 reduction, you should also go with the rear 72T 8mm sprocket and 8mm chain and gear box sprocket of your choice. Since it is 8mm drive, the 72T rear uses no more real estate than a 44 or 48T sprocket in 1/2 drive. By using 8mm, you will get better performance, better clearance, and better ratios since you can get gear box sprockets of 11T, 14T, 17T and 20T. No more changing rear sprockets to get the ratios you need. Simply swap out the gear box sprocket and that is all ! No kidding. It is fantastic. Also.. You can make the gear box into a wet gear box by pulling it apart and using gasket maker to seal the 2 half, and then drill a hole and add 7cc of motor oil and then plug your hole. Any way.. At $39.99.. These new Gear boxes will sell fast.. Here is the link to the page where you can find them.. Enjoy the ride... ENGINE_KIT_PARTS_PAGE_2
