Description: REVERSE GEARBOX BUILDER'S KIT Please see common questions at the bottom in green Specifications: Dimensions (approx) 12.4" L x 6.0" W x 7.4" H when fully assembled Shipping Weight: 10 Lbs (Built weight - 23 lbs) Forward Ratio: 1:1 Reverse Ratio: 2.14:1 Input Drive: Flat Flange (6) 5/16-24 threaded holes on a 2.50" BC Output Drive: 1.25" - 19 Spline Torque Limit: 500 ft-lbs RPM Limit: 6000 RPM Up for purchase is a "Builder's Kit" of our popular reverse gearbox. The kit consists of the items shown in the third picture, which are (1) input shaft/sun gear, (1) ring gear, (3) planet gears, (1) output shaft, (1) shift fork, and (2) snap rings. The drawing labeled To Be Made, are the parts the buyer has to machine or fabricate. This listing will also include a flash drive with PDF instructions, 2D PDF drawings with dimensions and tolerances, 3D STEP files to help when CNC machining, and a few reference pictures from the 3D model. I do not include any PDF or STEP files that list any proprietary information for the gears. I will continue to update the instructions as needed if I receive questions or comments, and I will continue to forward any revisions to the buyers. I can provide 2D drawings and the instructions in advance of purchase for you to review but I have no way to attach them here. I do not offer refunds due to the proprietary nature of the parts and drawings. I will be as transparent as possible to try and eliminate any concerns or confusion before purchase. If someone has a machine shop and is interested in building multiple gearboxes, contact me for a bulk discount for additional sets of gears. I have added a Bill of Materials (pics 6 and 7) listing what you will need to provide. The items listed as BUYER in the Vendor column aren't commercially available and will need to be machined by you or a shop of your choosing. Do not hesitate to contact me with any questions you may have. If the question may be of use to others, I will revise the listing with the questions. Thank you. COMMON QUESTIONS 1. Is this a complete gearbox? No, it's not, the only items included are shown in the third picture. The first two pictures are for reference and what the gearbox will look like after you build it. 2. Can the output shaft be used as the input? Yes it can, but reverse will be over-driven, meaning the flanged "output" shaft will be spinning 2.14x faster than the splined "input" shaft. 3. Will this gearbox work behind my (Hayabusa, R1, ZX10, etc) engine? Most likely yes, but I can't guarantee the gearbox will work behind that engine AND survive your application. 4. Can the gearbox be used in inline, shaft drive vehicles i.e. legends cars? Yes. The gearbox will need to be mounted with the output shaft pointing towards the rear axle and the flange will need to be parallel with the sprocket on the engine. Run a short chain between the transmission and reverse gearbox, then use the splined output shaft to connect to a driveshaft. Dana Spicer 2-4-6341 has the correct spline and uses a 1310 u-joint. 5. Will the gearbox work in a 4x4 buggy with a transfer case? Absolutely. The application is similar to the shaft driven application, however you don't necessarily need a driveshaft. Just connect the splined output of the gearbox directly to the input of the transfer case via a splined u-joint yoke. Dana Spicer 2-4-6341 has the correct spline and uses a 1310 u-joint.
