Cat 3 Hydraulic Top Links with Hook
These Cat 3 hydraulic top links with hook have a ball joint at the other end. All four have an 80 mm bore and 40 mm piston rod, shown as 80/40 mm. Mounting dimensions and length ranges differ.
Hook with Ø32.4 mm mounting holes
SPH320057 and SPH320058 have Ø32.4 mm mounting holes at both ends. Check the full hook-and-ball combination, mounting widths and clearance as well as length and stroke.
| Product · bore/rod | Length¹ | Stroke |
|---|---|---|
|
SPH320057 80/40 mm |
585–795 mm | 210 mm |
|
SPH320058 80/40 mm |
655–935 mm | 280 mm |
¹ Retracted–extended length measured center-to-center. Open the product for all mounting dimensions and supplied components.
Cat 3 hook with Ø25.4 mm mounting holes
SPH320055 and SPH320056 combine a Cat 3 hook with Ø25.4 mm mounting holes at both ends. They are deliberately also included in the Cat 2 range. Hook category alone does not determine fitment; check the ball, locking mechanism and complete drawing.

Which dimensions should you compare?
A suitable hydraulic top link must match both the mounting points and the required adjustment range. Check these points before ordering:
Category and mounting dimensions: compare the pin size and the width or clearance available at both ends.
Retracted and extended length: check the measurement points on the technical drawing and compare the full range with your application. Stroke alone is not enough.
Hydraulic controls and connections: check the required controls, hose length and couplings on the product page and on your tractor.
Also compare the connection and profile of the quick couplings. The same nominal connection size alone does not confirm that two couplings will fit together.

Frequently asked questions about hydraulic top links
Do all Cat 3 top links have the same mounting holes?
No. SPH320055 and SPH320056 specify Ø25.4 mm; the other models have mounting holes measuring Ø32.4 mm. Check both ends on the individual drawing.
Is stroke the same as overall length?
No. Stroke is the piston rod travel. Also compare the retracted and extended lengths, using the measuring points shown on the drawing.
