Precisely calibrated 123/05403 gas spring (strut) by GX-AFTER. This component is responsible for assisting the opening and holding open the operator's cab door. Dedicated to older generations of JCB 3CX and 4CX backhoe loaders (models produced before 1997, e.g., Project 8 / Grey Cab). The strut features a specific total length of 340 mm, distinguishing it from newer versions.
GX-AFTER is synonymous with reliability in the spare parts segment. Our gas struts are nitrogen-filled under strictly controlled pressure, ensuring smooth operation and maintenance of nominal lifting force over a long service life.
| Machine Type | Models / Years |
|---|---|
| Backhoe Loaders | 3CX, 4CX (manufactured before 1997) |
| Cab Type | Older type cabs (Grey Cab / Project 8) |
Note: Machines after 1997 (Project 12/21) usually use longer struts. Please measure the old part.
The strut is typically mounted on ball joints. If the mounting sockets on your machine are worn, we recommend replacing them to ensure smooth operation of the new telescope.
A worn gas strut may not hold the heavy machine door, causing it to fall suddenly and uncontrollably. This poses a risk of trapping the operator's limbs. Replace struts in pairs as soon as you notice a drop in holding force.
The gas telescope compensates for the weight of the door, making it easier to open and preventing it from closing automatically (e.g., in the wind).
