Q & A

What's in the Box

This 9" Ford overhaul kit includes: pinion pilot, pinion shaft, pinion nut, pinion seal, gasket, shims, crush collar, sealant, gear marking grease, brush and Loctite. Ring gear bolts not included.

NOTE: All Ford 9" full spools use overhaul kit 9190950-31, even if they are a 28-spline spool. The 9190950-31 contains the large I.D. standard O.D. carrier bearings and pinion bearings needed for use with our full spools.

If you are using the H.D. nodular iron center section which uses the large diameter carrier bearings, order kit 9190950-31s, which also includes the large pinion bearings for use with the Daytona pinion support.

Excellent parts and great price. Makes my job easier.

June 23, 2015
I have used this product for years and have never heard a complaint from any customer. Having a complete kit like this is the only way to go. If it had the option for ring gear bolts for posi units then I would have everything in one box.
Yes, I recommend this product.

Perfect for gear changes and overhauls. It would be nice if they included a spacer/shim kit rather than the crush sleeve. Well designed kit provides everything you need.

Why does the 31s kit come with pinion bearings for a daytona pinion support but only has a short crush sleeve that is unusable in a daytona support? I needed an overhaul kit with 3.063 side bearing od with standard pinion bearings, you don' offer that so I bought the 31s kit and went and and got your daytona aluminum pinion support. The crush collar is too short so i've got to find a spacer kit somewhere.

You will need to use a solid pinion spacer and shims for use with the Daytona pinion support which is part number 9190921.

I want to replace the seals and bearings in my 69 mustang mach 1. It has the 9" rear end, so I am assuming this kit will work. I see this comes with a different size carrier bearing. Which one is appropriate for my vehicle? 28, 31 or 31s.

Part number 9190950 You need to verify the bearing specifications in your housing for kit to order. Normally the 31 or 31s kits fits most applications but below are the bearing numbers and dimensions for match up. * 9190950-28 o Includes carrier bearing # LM501349 o 28-spline axles DO NOT guarantee that the LM501349 bearings are used in the carrier. If in doubt, double check the bearings used and then order accordingly. * 9190950-31 o Includes carrier bearing # LM102949 o 31-spline axles DO NOT guarantee that the LM102949 bearings are used in the carrier.

The "s" on the end of the part number, does it mean it's for a spool? I've read the side note about the full spool uses the 31 spline kit, just wondering the difference?

The difference is in the size of carrier bearings. The 31S uses bearinf #LM603049 this is 3.063" od. The 31 kit has a bearing #LM102949 that is 2.879" od. All full spools use part #9190950-31

Lubrication Engineers SAE 90 Weight Gear Oil, 1 Gallon
(Part #91044090)
                        Whether you're running a stock flattie and rearend or hopped-up overhead and quick change, you need to run a good gear lube. Remember that your rearend was designed fifty plus years ago and needs all the help it can get. 

The biggest improvement you can give it is a lubricant that will allow the gears to survive the highway speeds that cars see today. L.E. gear oil is what we use in our 350 mph streamliner, that uses a V-8 quick change, without failure. The "red stuff" provides superior lubrication for long gear life. You can't win if you don't finish. We suggest 90 weight for the street and 140 weight for extreme uses.
