Speedway Gearbox

T5 Speedway Gearbox

 

After 18 months of testing and development, we are about to start production on the first batch of Race Products Speedway T5 Gearboxes.

These are a heavily modified version of the Borg Warner T5 Gearbox suitable for speedway use.

The main casing of the gearbox is CNC Milled and fitted with our CNC machined bearing carrier to increase the rigidity of the casing.

The gearbox is then fitted with our straight cut gearset, these are designed and manufactured by us, from Motorsport Grade Ultraclean EN36a Chromoly, and heat treated to our specifications. The heat treatment process is carried out to the highest standards by the same company that does all of our V8 Supercar parts.. The redesigned gearset uses 5th gear as a “Take Off” gear, followed by ultra close ratio gears from 1st to 3rd. (4th gear is not used)

A standard reverse gear is fitted.

For additional strength and reliability we also fit our CNC Machined Mainshaft Pilot Support Bridge and bearings.

The new gearset also features a “Click fit” input shaft system, this means the input shaft is installed after the gearbox is fully assembled. This makes it simple to supply the gearbox to suit different cars, as the input shaft takes seconds to fit. Current Input shafts are: Falcon, Commodore, Escort and Silvia, others are available on request.

The gearbox is then fitted with a modified selector system, two breather outlets, and is fully rebuilt using all new quality bearings, synchros, gaskets, seals and other service parts.

The supplied price includes all parts and labour to modify and supply a fully assembled gearbox, ready to install.
