The best dump trailer telescopic cylinder depends on your dump body length, required stroke, and whether you need a hoist-only assembly or a standard kit. These five options cover bodies from 8 to 24 feet: the 90-inch models suit shorter bodies, while the 108-, 120-, and 168-inch models serve progressively longer bodies. Check the stated fit range and included hardware before choosing.
| Product | Stated Body Fit | Best For |
|---|---|---|
| 7k, 90-inch Hoist Only | 8–12 feet | Shorter bodies; hoist-only setup |
| 12k, 168-inch Hoist Only | 20–24 feet | Long bodies needing extended stroke |
| 7k, 90-inch Standard Kit | 8–12 feet | Shorter bodies; standard kit |
| 12k, 108-inch Hoist Only | 10–14 feet | Mid-length bodies |
| 12k, 120-inch Standard Kit | 12–16 feet | Longer mid-size bodies |
Primary Mover 7k 90-Inch Hoist-Only Kit
This telescopic cylinder kit is listed for 8- to 12-foot dump bodies and has a 90-inch stroke. The product description states a dumping capacity of more than 20 tons and includes a high-flow hydraulic power unit with upgraded #8 SAE ports.
Best for: Owners with a shorter body who want the hoist-only configuration. It was selected for its clearly stated fit range, stroke, and hydraulic power unit details. The listing also describes installation as designed for integration with an existing hydraulic system.
Check before buying: It is identified as “Hoist Only,” so confirm which components your trailer setup still requires.
Primary Mover 12k 168-Inch Hoist-Only Kit
With a 168-inch stroke and stated fit for 20- to 24-foot dump bodies, this is the longest-stroke option in this selection. The listing describes a capacity of more than 30 tons and says the telescopic design provides an extended range of motion. The kit includes an H-frame and top mounting brackets with the cylinder.
Best for: Buyers matching a long dump body who need the listed extended stroke and mounting brackets. It stands apart from the other options because its stated fit range reaches 24 feet.
Check before buying: This is labeled “Hoist Only.” Verify the included parts against your installation needs, and make sure the 20- to 24-foot fit range matches your body.
Primary Mover 7k 90-Inch Standard Kit
This 90-inch model is listed for 8- to 12-foot dump bodies and states a dumping capacity of more than 20 tons. Its described features include a high-flow hydraulic power unit with upgraded #8 SAE ports and installation designed for integration with an existing hydraulic system.
Best for: Buyers seeking a standard-kit option for a shorter body. It provides the same stated stroke and body-fit range as the 90-inch hoist-only listing, making kit type the key comparison point.
Check before buying: The listing’s feature text does not detail every component included in the standard kit. Confirm the kit contents before ordering.
Primary Mover 12k 108-Inch Hoist-Only Kit
This 108-inch-stroke cylinder kit is listed for 10- to 14-foot bodies, with a stated capacity of more than 30 tons. Its features include a telescopic design and a heavy-duty H bracket with sturdy upper mounting hardware, intended to support stability under substantial loads.

Check before buying: The product is labeled “Hoist Only.” Confirm what else is needed for your hydraulic system and installation.

Best for: Buyers with a longer mid-size body who need a standard kit and want the stated mounting hardware. It is a practical comparison against the 108-inch hoist-only model when body fit and kit type differ.
Check before buying: The listed fit range is 12 to 16 feet; verify your body length and mounting arrangement before selecting it.
Buying Guide: How to Choose a Dump Trailer Telescopic Cylinder
Which stroke length matches your dump body?
Start with the product’s stated body-length range, then compare its stroke. The options here pair 90 inches with 8- to 12-foot bodies, 108 inches with 10- to 14-foot bodies, 120 inches with 12- to 16-foot bodies, and 168 inches with 20- to 24-foot bodies. Treat these as listing specifications, not a substitute for checking your trailer’s dimensions and mounting layout.
Should you choose hoist only or a standard kit?
Compare the kit label and included components with what your trailer already has. The 90-inch and 168-inch products are explicitly marked hoist only. The 90-inch and 120-inch alternatives are called standard kits. The 168-inch listing specifically mentions an H-frame and top mounting brackets, while the 120-inch listing describes bracket and mounting hardware.
How should you compare capacity and hydraulic details?
Several listings state capacity above 20 or 30 tons. Compare those claims with your equipment requirements, but do not assume a stated capacity alone confirms fit or suitability. Also check whether the listing specifies a hydraulic power unit and port details, and verify the components needed for your existing hydraulic system.
