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.

Sold Individually.

ALL SYNCHRO BELLHOUSING

Made from our own pattern equipment these are cast in top quality Aluminium and now Magnesium, both are heat treated. Both are far superior to the original in terms of strength and accuracy of alignment.

We have a choice of original clutch release fork mechanism or a solid pad in the centre to accept your own co-axial release mechanism. Also the choice between the original large starter dog housing (for the original starter) or our slim line design (when using our modern pre-engaged starter) which helps to make it possible to remove the gearbox fromthe car leaving the engine in place.

Now also a choice to suit 4.2 ring gear as well as 3.8.
