USA Standard Gear (ZK F9-A-SPC) Master Overhaul Kit for Ford 9 LM102910 Differential with Solid Spacer

Nice heavy gears, good value

Complete kit with good quality bearings and assortment of shims. Installation of my new 12 bolt 8.875 ring and pinion went smooth.

Everything I needed for rebuilding my rear end without having to run around every where!

Product didn’t work for my 06 Silverado rear end. Bearings are different and return window has been closed because I took to long to rebuild it.

A little noisy on slow turns but this thing locks up great.

I appreciated the packaging for every piece except for the gasket. No rips or tears, just very squished and bent. Seems still usable especially if the customer just plans on using RTV, or RTV additionally. This review is to just let the manufacturer know 🤙

Expensive kit compared to 4cyl diffs, but I didn’t find anything cheaper for my v6 2wd rear diff. Had to chg pinion depth with new brgs but had the shims in kit to do it. Good quality parts kit.

Parts look good well packaged

Even though it stated that it fits my 2012 Ram 4x4, IT DOESN'T!!! the only thing that was the right fit was the carrier bearings. The ring gear bolts, TOO SMALL. The pinion bearings, WRONG sizes, the pinion nut, WRONG SIZE. Plus missing shims which I didn't need anyway. My red seal mechanic that rebuilt hundreds of differentials calls me to tell me that this is the wrong kit! I had to buy the pinion bearings and nut locally at the dealer which charged way too much!! I will be returning the parts that didn't fit and will demand my money back.

The installer said this was a really good kit and everything went together really well.

Doesn't include ring gear bolts even though it states in listing there included. Not a master rebuild kit if everything is not included.

Ordered a kit for a gm 10bolt 8.2 and was giving the right kit everything is right beside the Pinion bearing it's to small and the part# on the bearing is for a ford/dodge rear end

2 out of the 4 bearings (the side bearings) were not KOYO as stated. From my online research I found out the supplied bearings were .002 smaller I did not use them and had to source them from Toyota. I also did not use the supplies outer pinion bearing.I would not order again.
