Exmark 103-2171 Caster Spacer Wheel Kit Turf Tracer Ranger Metro S X Series

What It Is

This Exmark 103-2171 Caster Spacer Wheel Kit replaces worn or damaged front caster wheels and spacers on select Exmark zero-turn mowers. It’s designed to restore smooth steering, reduce vibration, and prevent caster wobble during mowing.

Fitment & Compatibility

• Exact fit for: Exmark Turf Tracer, Ranger, Metro, S-Series, and X-Series models with front caster wheels.
• What to check before buying:
  • Measure your current caster wheel bolt pattern (center-to-center spacing) and wheel diameter. This kit typically fits 11x4.00-5 or 13x5.00-6 wheels, but verify your model’s OEM specs.
  • Confirm your deck size—this kit is common on 36” to 60” decks, but not all.
  • Check your mower’s serial number against Exmark’s compatibility list (available on Exmark’s site or by calling support).
  • This is an OEM Exmark part, not an aftermarket clone—guaranteed bolt-on fit for listed models.
• Not compatible: Older non-Exmark mowers or Exmark models with non-standard caster mounts.

Key Things to Know

• Quality: OEM Exmark steel spacers and bearings are durable; aftermarket kits often use softer metals that wear faster.
• Installation difficulty: Moderate. You’ll need a jack or blocks to lift the front, plus basic wrenches. Expect 30–60 minutes for both wheels.
• Common gotcha: The kit includes spacers and hardware—don’t reuse old bolts or washers; they may be corroded or stripped.
• Maintenance: Grease the caster pivot after installation to extend life. If you mow on gravel or rough terrain, check tightness monthly.

Should You Buy It

Buy this if you own a compatible Exmark zero-turn and notice caster wobble, uneven tire wear, or rough steering. It’s a direct OEM fix that eliminates guesswork—worth the $120 for owners who want reliability over cheaper aftermarket options. Not for non-Exmark mowers or those with intact casters.
