Part Number: 21171969
Description:
This listing is for a genuine Volvo rear right cabin attachment / cab support assembly with integrated spring and lock mechanism, suitable for late Volvo FH and FM trucks and Renault T series. According to Volvo and BAS Parts data, OEM reference 21171969 is a right-hand cabin attachment used on Volvo FH (2013 onwards) and FH4 Euro 6 models, and cross references to Renault number 7421171969 for T range vehicles. The housing on this unit carries casting/lock number 22247233, which is the cab lock mechanism that is part of the complete attachment assembly and is listed as interchangeable with 21171969 in various parts catalogues.
The assembly consists of the heavy duty steel mounting bracket, coil spring cab support, and upper cabin locking mechanism. It is installed at the rear right side of the cab to control cab movement, absorb vibration and securely lock the cab to the chassis when in the driving position. This type of rear cab suspension/attachment is critical for ride comfort, noise reduction and cab safety during normal operation, tilting and servicing.
Compatibility (based on OEM data and online catalogues such as BAS Parts and Autoline):
- Volvo FH (2013–2022) including FH4 Euro 6 tractors and rigids.
- Volvo FH (2021–onwards) updated models.
- Volvo FM and FMX-4 series (2013–onwards) where equipped with this type of rear RH cab attachment.
- Renault T Range (2013–2021) and Renault T Evolution (2021–onwards) using cross OE 7421171969.
Always verify by OE part number 21171969 or 7421171969 and your VIN before purchase, as cab type (Standard, Globetrotter etc.) and suspension options can vary.

Condition and testing:
This part was removed from a donor vehicle that was road-tested before dismantling; the cab suspension and locking were confirmed to operate correctly with no excessive play or abnormal noises. After removal the unit received an external clean and a light cosmetic repaint on the bracket section. There are visible signs of previous service life such as light surface rust near the lower mounting foot and on the lock jaws, marks on the spring paint and general wear to fixings, but the structure is sound with no cracks or deformation seen. All mounting holes appear round and undamaged and the lock mechanism actuates smoothly by hand. Graded as B: used with moderate cosmetic wear, fully functional and ready to install.
Installation notes:
Professional installation is strongly recommended. The cab must be safely supported before removing or refitting the attachment. After mounting, ensure all bolts are tightened to the manufacturer’s torque specifications and check cab alignment, locking operation and suspension travel. Some fleets may require calibration or a safety inspection after cab suspension work; follow your workshop manual and local regulations.
