Product Information

This is Yukon Gear & Axle's standard open spider gear kit for the 9.75 inch Ford rear axle with 34 spline axles, covering 2011-2025 Ford F-150 trucks. It's a spider gear set for the open differential carrier, built as one complete replacement instead of parts pieced together from different sources.

Why Upgrade to Yukon Spider Gears

Per Yukon Gear & Axle, here's what this kit changes:

  • Higher quality materials than the factory spider gear set, aimed at a longer service life under regular driving.
  • Manufacturing techniques the brand says go beyond OEM production, part of what's behind that longer-lasting claim.
  • Everything needed for a complete, proper spider gear set replacement in one kit, so you're not hunting down individual gears separately.

Fitment Notes

Fits 2011-2025 Ford F-150 Base and Raptor trucks, and 2021-2025 Tremor trucks, all with the 9.75 inch rear axle and 34 spline axles. Does not fit F-150 Lightning or Raptor R.

Install and Honest Talk

This is a set of spider gears for the F-150's open differential carrier, the kind of part that goes in on a case-apart job, not a bolt-on swap. That's real labor: budget for a shop visit unless you already do your own differential work.

What else you need: check the included instructions or a Yukon install guide for the specific tools, gear oil, and any other hardware this job calls for.

No Robots. Just Car People.

Buying parts for your Mustang or F-150 should not feel like homework. Too many stores bury you in a giant catalog, slap the same distributor description on every product, and leave you guessing whether it even fits.


We do it the other way. We carry the brands you already trust, we tell you what a part actually does, and we give you the truth about the tradeoffs before you spend a dollar. Drone on that exhaust. Ride quality on those springs. Whether you need a tune. The stuff the big catalogs leave out.
