DIFFERENTIAL MOUNTINGS—STABILITY CUPS, ALL
"The Latest Diff Mount Technology for Fast Road and Full Race"
The English racing gurus are now saying that original rubber diff mounts with new
machined aluminium stability cups work better in fast road and racing conditions than
urethane mounts. Precision machined aluminium cups take the place of the large
washers under the rear mounts only to limit flexing of the mounts during stress from
hard cornering and acceleration. The gurus say that the axle shafts stay better positioned
using this technology, and there is some indication that frame bolts are less stressed
when the cups are fitted. This is what the gurus are saying, and U.S. vintage racers
seem to agree. That is why Joe Alexander of Alexander Racing Enterprises (ARE) has
produced a run of beautifully-machined aluminium cups for TRF customers.
