Or - 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.<br /> These must run with BJ8 steel baulk rings.<br /> 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.</p> <p><a href="http://www.bighealey.co.uk/content/straight-cut-gear-sets">read more</a></p> Gearbox Mon, 22 Dec 2008 12:58:53 +0000 admin 15043 at http://www.bighealey.co.uk http://www.bighealey.co.uk/content/rated-main-shaft-0 <p>An improvement on the original that uses a higher grade steel and a redesigned 3rd gear locking ring to prevent cracking and breaking.
