New ratio Pro Stock gears are available in specially prepared thirdmember assemblies. MW designed 9-1/2" Richmond ratios are in stock and ready for shipment in specially prepared complete thirdmembers. The ratios available in the 9310 alloy 32 spline pinion are: 5.00, 5.11, 5.14, 5.17, 5.20, 5.25, 5.29, 5.33, 5.38, 5.43 and 5.50. Other 28 spline 9-1/2" ratios can be assembled with the same components. The assemblies feature the Supra-Fin processing that reduces friction and eliminates material transfer normally found in the break-in-process. We also use a Sub-Zero thermo-treatment to eliminate the possiblity of retained austenite. The gears feature a 9-1/2" diameter 32 spline input (the same size as transmissions) eliminating an obvious weak link in the drive system. We use a ceramic double angular contact pinion support bearing that is lighter, reducing friction and adding to the pinion. Special angular contact spool bearings are a huge advantage in reducing friction and maintaining correct ring gear position. A low drag pinion seal, used in conjunction with our aluminum pinion yoke reduces the pre-load drag by approxiamtely 5 inch punds.
We have a limited number of refurbished Low Friction Thirdmembers for sale at discounted prices. They include a new sub-zero treated and Supra-FinTM polished 9.5" gear set. Call for available ratios and prices. |
