Description:

Set of front and rear ring and pinion sets for 4wd Excursion. 4.56 ratio. Installed by a professional mechanic known in my area for gear installations. Ran with Redline 75W140 synthetic gear lubricant and had proper break in procedure and fluid changes at 500 miles. Only had on the EX for about 10K miles and decided to switch to 4.88 as I had plans for larger tires.  Gears look like new. Paid about $650 for the set.  Asking $150, buyer pays shipping costs. 
Front set weighs 17 lb and box dimensions are 5.5" x 11.25" x15.5".
​Rear set weighs 27.5 lb and box dimensions are 6"х 13.5"x 18.75"
