The TGC25008V is another Clevis Mount variant with an 8″ stroke and a 2.5″ bore, designed for dependable pneumatic tailgate control. The in-cab control option enhances operator safety by permitting tailgate operation from inside the cab, reducing the need to approach the tail end of the truck during cycling. The cylinder’s aluminum construction supports rigorous daily use and simplifies maintenance tasks on job sites with heavy-duty requirements.
Buyers Products TGC32506VSPK Tailgate Cylinder Kit

The TGC32506VSPK kit pairs a heavier 3.25″ bore with a 6″ stroke in a Clevis Mount configuration. This setup is well-suited for demanding tailgate tasks that require higher force and tighter control. With a robust aluminum body and pillow valves that protect the piston from unintended contact, this model offers reliable performance in tough field conditions. Installation is straightforward for compatible dump truck chassis and tailgate assemblies.
Buying Guide: Key Purchase Considerations
When choosing an air cylinder for a dump truck tailgate, consider these factors to ensure an optimal, long-lasting fit:
- Stroke length and bore size: Longer strokes deliver greater tailgate travel, while larger bores increase force capacity. Match these to your tailgate geometry and load.
- Mounting style: Clevis mounts are common for tailgates; hinge mounting options offer flexibility in unconventional configurations. Confirm compatibility with your tailgate frame.
- In-cab control: If operator safety and efficiency matter, prioritize models with in-cab control. This feature lets drivers operate the tailgate without leaving the cab.
- Construction: Aluminum bodies provide corrosion resistance and light weight, ideal for outdoor work sites. Look for pillow valves to prevent piston collisions during operation.
- Durability and maintenance: Consider extruded aluminum or steel bodies for rugged environments, ease of maintenance, and availability of replacement parts.
- Installation kit contents: Some kits include tubing, fittings, and mounting hardware—these reduce separate purchasing and ensure compatibility.
- Availability of replacement components: Ensure spare seals, valves, and rods are readily available to minimize downtime.
For fleet maintenance, evaluate total cost of ownership, including installation time, potential downtime, and compatibility with existing tailgate hardware. Compare models with and without in-cab controls, and assess whether your typical workloads justify a higher-capacity bore or longer stroke. Consider the environmental conditions—dust, moisture, and vibrations—that your tailgate endures, and select cylinders with corrosion-resistant bodies and protective features where needed.
