3.90 Gear Set...Excellent
Really good set of 3.90 gears. Works exceptionally well on my 1998 GMC pick-up truck. I had changed the wheel and tire dimensions and therefore changed the gear ratio

Great gears
Works as intended. Quiet. Challenging to install for someone that has never installed this on a trutrac.
