FORD GEARBOX SPECIALIST
Modified * Improved * Original & Special Ratio * Sports & Racing Gearboxes
This page contains details of the excellent
gearboxes produced by BGH Geartech (Brian G Hill). Disclaimer - I have no connection nor
vested interest whatsoever with BGH other than as an extremely satisfied customer
BGH produce a range of close ratio uprated gearboxes based on Ford gearboxes. These are especially suited to competition and kit car usage and are relatively inexpensive compared to the alternatives. As well as improved ratios, the gearboxes are modifed to improve lubrication (and therefore strength) the quality of the synchromesh and shift as well as a non-loss breathing system.
If your first gear is so low it is useless or if your engine is always falling off the cam, you probably need a close ratio gearbox, or at least one with a higher first gear. When you have a peaky engine, a close ratio gearbox transforms the way the car can be driven, the speeds in each gear also go up substantially, which helps in the traffic lights grand prix. If you're are in competition, a close ratios gearbox is just about essential.
In addition to their excellent close and ultra close ratio gearboxes BGH also offer an exchange rebuild service for standard Ford gearboxes at very competitive rates. You will not find BGH on the web, nor do they use computers in manufacturing, what you will find is honest no-bullshit advice based on many years of experience and a high quality product. Brian Hill was instrumental in designing the six speed gearbox currently used by Caterham Cars and is an experienced engineer and designer of the 'old-school'..
BGH also provide a driveshaft manufacture and differential service 'SHAFTTECH' to mate any type of diff or transaxle to any kind of hub. If you are having a problem mating a Renault transaxle to Cosworth hubs or any problem of this nature, give Brian a call.
I have personal experience of the BGH products as well as those from other manufacturers and would use a BGH gearbox in preference. BGH have featured in CCC magazine and his gearboxes have been used to good effect in some of the staff cars there. They are the best kept secret in the gearbox market, I hope this page helps in bringing these excellent products to a greater exposure.
