BRASS GEAR LEVER BUSH
CNC machined to exacting standard from our own drawings in the correct hard wearing grade of bronze.
STEEL BAULK RINGS
Another product developed and produced by Denis Welch Motorsport.
At last now available after extensive testing
we are satisfied these will cure your synchro problems.
CNC machined in the UK to our specifications with the aid of original BMC drawings.
REVERSE SELECTOR FORKS
Reproduction of the original by ourselves.
Available bare or complete with both indent springs and plungers.
LAYSHAFT
Top quality reproduction of the original to the highest standard, manufactured by ourselves due to the short lifespan of our competitors products.
OVERDRIVE CLUTCH BRAKE RING
A reproduction of the original in cast iron, as the original with precise control of the cone angle and surface finish to help avoid problems with the sliding member sticking.
STRAIGHT CUT GEAR SETS
Available in two ratios:
- Tulip, the original works rally ratios, having a large jump between 3rd and 4th gear, therefore needing a 22% overdrive to split the gap and effectively creating a 6 speed gearbox.
- Sebring which are similar to the works sebring race ratios, having a higher first gear with a close gap between all the gears, therefore only needing the overdrive on top to create a 5 speed gearbox.
Today most people prefer the Sebring ratios as they are less confusing in a heated situation. They are both manufactured solely for us with Molybdenum coated synchro cones to improve the synchromesh, giving a smoother and faster gear selection. These must run with BJ8 steel baulk rings.
They are designed to run on a BJ8 main shaft and layshaft which can be installed into an earlier side or centre change gearbox (except BN1) with slight modifications to the centre case.

UP-RATED MAIN SHAFT
An improvement on the original that uses a higher grade steel and a redesigned 3rd gear locking ring to prevent cracking and breaking. These shafts are also spline ground as original, not hobbed as our competitors, thus ensuring the gear selector hubs fit smoothly.
SELECTOR HUBS
Made to our design, these are not only a little lighter than original they also do a much better job of staying in gear. Also a direct replacement for standard.
DIPSTICK 'O' RING CONVERSION
Stop another annoying oil leak. A steel slug with an 'O' ring seal, to simply slip onto your dipstick in place of the felt seal.
3rd / 4th SELECTOR FORKS
Made from our pattern equipment with the best material, increased in thickness where necessary these are much less likely to crack and brake.
They are also a direct replacement for the standard.
