Diff gearsets for testing different ramp angles to tune the limited slip TBR and vehicle behavior.  Standard differentials are assembled with the medium ramp angle (helix angle in our Torsen-type diffs) so you can test and tune with these additional higher and lower angles to increase or decrease the diff's characteristics.  Couple with our fluid options or our new externally adjustable preload diff for the ultimate in adjusting every aspect of the differential.

Introductory pricing for pre-orders before July 31st.  Increasing to standard price thereafter.
