HGT Bell Housings

HGT Bell Housings


We have a bell housing to suit most of the popular race and performance engines.


Whilst some say that “any old bell-house will work” or “I'll buy one from my local guy – he’s cheap and cheerful”; this is one of the most critical parts in the whole drivetrain setup. The front and rear-facing plates must be 100% parallel, centres must be perfectly aligned, bolt-holes must be drilled in exactly the right position and at exactly the right angle. Many so-called “gearbox problems” are actually the result of a poorly built, machined or drilled bell housings. Misalignment of just 10 microns can be sufficient to cause premature bearing failure or abnormal shaft or internal wear. It’s simply not worth trying to “save a little” when there’s a sizable sequential gearbox investment at stake. All HGT Precision bell housings are built to handle race loadings and come with hardware to make the installation simple. As is standard practice in the racing industry, we highly recommend that you index the Bellhouse to your crank to ensure the drive train is perfectly aligned no matter which brand of bell house you use. It only needs to be done once.

All HGT bell houses feature our "Patented" Vernier Bell technology which eliminates the need for offset dowels as the adjustability is built right into the Bell housing.
