GBR 3.90 ring and pinion kits - new
I have front and rear GBR 3.90 gear kits that are not going to be used. These are similar to the GBR 4.11, but offer a 9% gearing reduction versus 12%. The fronts are reverse cut for strength plus these should be a little stronger than the 4.11. The rear pinion gear works with both the 4-bolt and 3-bolt flanges. The 3.90 ratio brings back stock gearing with full 32" tires.
The kits are new in the box from GBR last year. All set up parts included (seals, shims, nuts).
Paid $750 shipped from GBR, asking $625 shipped within USA lower 48 states.
Also, I may have some flanges, spacers, bearings, diff. housings, etc....if needed.
