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.

Lubrication Engineers SAE 90 Weight Gear Oil, 1 Gallon
                        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.
