4PK Genuine OEM Wright C-Type Notched Caster Spacer 13990022 Wright Stander Mower

What It Is

This is a genuine OEM Wright caster spacer (part #13990022) designed for Wright Stander mowers. It spaces the caster wheel assembly correctly on the deck, preventing wobble and premature wear on the caster forks and bearings.

Fitment & Compatibility

• Exact fit only for Wright Stander mowers (not for other brands or zero-turn models).
• Compatible with Wright models that use the C-Type notched caster design—check your deck’s caster mounting plate for a notch that matches this spacer’s profile.
• Measure before buying: The spacer has an inner diameter of ~0.5” and an outer diameter of ~1.0”, with a thickness of ~0.25”. Verify these match your existing spacer.
• OEM only: Aftermarket spacers may lack the notch or correct thickness, causing slop or binding. This Genuine Wright part ensures exact fit.
• Common models: Wright Stander (all generations), Wright ZK, and Wright Sentar—but always confirm your deck size (32”, 36”, 48”, 52”, 61”) and year.

Key Things to Know

• Installation difficulty: Easy—just remove the caster wheel, slide out the old spacer, and replace. No special tools needed.
• Common gotcha: If your caster is already wobbling, the spacer alone may not fix it. Inspect the caster fork bearings and wheel hub for wear first.
• Quality: Genuine OEM steel construction with precise notch alignment. Aftermarket versions often lack the notch or are slightly undersized.
• Price point: $38.99 is typical for a genuine OEM spacer. Cheaper alternatives may cause premature caster failure.

Should You Buy It

Buy this if you own a Wright Stander mower and need to replace a worn or missing caster spacer—especially if you notice side-to-side play in the caster wheel. It’s the correct OEM part for a quick, reliable fix. If your caster fork or bearings are damaged, replace those first, but for the spacer itself, this is the right choice.
