Set up in 1999, Deland Car Accessories Co., Ltd. is a professional China dog gearbox manufacturer and designer. It has years of OES and OEM dog gearboxes production experiences and passed ISO9000 and the TUV certification of ISO/TS16949 quality system. Therefore, we can better fulfill customers' specifications and satisfy their changing needs, such as Ford, Opel, Benz, BMW, Nissan, Toyota, Mitsubishi, Mazda, Isuzu, Hyundai, Kia and Truck series.

When KAD decided to produce their own 5 speed race gearbox there were two main criteria which had to be met by the design. Firstly it should fit a standard gear casing without expensive modifications. Race engines can have blow ups and replacing an expensive casing just adds to the misery. Secondly it should be direct drive in fifth, we figured that this would offer the maximum torque output at the point where aerodynamic drag was at its greatest: high speed. The other 5 speed boxes on offer were all of the over driven fifth type which meant torque would be lost when engaging fifth. The end result is a no compromise race gearbox that is easy to use with gear ratios ideally suited to today’s race tracks with their frequent slow to medium speed corners. The compact gear train fits into a standard A+ rod change gear casing and has straight cut gears with face dogs, typical of conventional racing gearboxes. The gears are manufactured from a vacuum arc remelted steel (VAR), this is a very high specification material which has higher strength and greater purity than commercially produced steels giving stronger gears and allowing a narrower gear width and lower frictional losses.

Quaife's technical department has placed particular emphasis on optimising the ratios for the QKE7H MA gear kit, specifically for higher powered cars using the TU5J4 16-valve engine, enabling significant performance improvements over the standard MA items. Toyota Landcruiser 75 Series HJ75 RECONDITIONED GEARBOX & TRANSFER CASE for 2H 4.0 diesel ->1/90 sold on the exchange basis. Warranty is AUSTRALIA WIDE 6 month parts & labour warranty. The selector forks are made from aluminium bronze which has good wearing properties and high bending resistance. The selector mechanism has been designed to offer a fast reliable change and the shift pattern has been arranged with first on a dog leg, to the left and back. The QKE7H features five gear ratios, with each gear being considerably wider than the standard MA items for enhanced durability, while the advanced ‘open face' four dog design ensures ultra-rapid gearshifts. Straight cut, close ratios allow tuned engines to remain in power band with minimal power losses.
