CMI 17-4 Stainless Steel Swing Axle Thrust Washers (Pair)
When you build a swing-axle transaxle for serious power, every part in the load path matters, including the humble thrust washer. CMI Precision Machining of Corona, California machines these swing axle thrust washers from 17-4 stainless steel heat-treated to H900, finishes them with a polished radius, and holds them to precise tolerances. They are sold as a pair, one for each side, and they are made in the USA.
Washburn's Metal is an authorized CMI Precision Machining dealer — genuine CMI parts, made in the USA, with full factory support.
These are the same specification of thrust washer that CMI supplies with its 300M racing swing axles: that axle kit is listed with "(2) 17-4 stainless steel thrust washers (heat-treated to H900)". Buying them separately lets you refresh a swing-axle build without buying a new set of axles.
Vehicle Fitment
- Application: VW swing-axle transaxles (the supplier describes these as swing axle thrust washers).
- Confirmed pairing: CMI 300M Racing Swing Axles, short spline 26 11/16", for 1961-1966 Beetle and Karmann Ghia sedans.
Please note: the supplier does not publish a thickness or inside and outside diameters for this washer. If you are matching an existing washer or setting side-gear clearance on another swing-axle application, contact us before ordering and we will help confirm fit.
Key Features and Benefits
- 17-4 stainless steel: a precipitation-hardening stainless alloy that combines strength with corrosion resistance.
- Heat-treated to H900: the H900 condition is the hardest standard heat-treat condition for 17-4 stainless.
- Polished radius: a smooth, radiused edge rather than a sharp stamped edge.
- Precise tolerances: machined, not stamped.
- Sold as a pair: two washers, enough for both axles.
- Made in the USA by CMI Precision Machining.
