Key Notes:

• Part Number: RD451-46380
• Type: Gas damper (gas spring) — cab front sliding window prop
• Weight: 0.40 lbs
• Application: Holds the cab front window in the open position during operation — the gas damper extends when the window is opened and maintains tension to keep the window safely propped at the desired position on applicable Kubota compact excavators
• Sold: Individually — one damper per order
• Condition: Aftermarket replacement part

Common Use Case or Symptoms: Use when the cab front window no longer stays open on its own, drifts closed during operation, or the existing gas damper is bent, leaking, or has lost holding force — a failed window gas damper makes it impossible to safely prop the front window open for ventilation on applicable Kubota compact excavators.
