For the street, our two most popular upgraded ratios are
3.91 and 4.10.
Both are still very usable daily and by compounding the torque that
gets to the wheels, provides improved acceleration at all
Engine RPMs with the 4.10 are 3200 RPM @ 80 MPH and top end speed
is still over 170 MPH.
Out of both ratios, the 4.10 is our preferred for performance on
N/A applications and 3.91 for superchargers.
For the track our diffs are unreal! Offering the longest
time before rebuilds avalible due to our attention to deatail and
excelent machine work we offer in house. Various LSD and ATB
options are available, and we can make a diff to fit any need.
