STRAIGHT CUT GEAR SET

Manufactured exclusively for us by two of England's leading gear manufacturers, these incredibly strong gears have the same ratios as the original close ratio E-Type gears, as set out in the attachment below.

The set comprises of all gears including reverse, all brand new manufacture. They will fit directly into any 4.2 all synchromesh overdrive or non-overdrive gearbox using the original type bearings and synchros etc. with no modifications or machining.

The competition set is made from a higher grade steel and being vibro deburred has a superior surface finish.

Heavy Duty Baulk Rings

Considerably stronger than the original, these will resist cracking, breakage and wearing out to a much greater degree. Two types are available.

Steel - designed for the most demanding drivers, mainly for racing.

Brass - for those slightly more sympathetic drivers who prefer a faster shift.

The steel may require routine servicing every season. Both fit the original or our straight cut gears with no modifications. Fits any 4.2 all synchro gearbox.
