Leaking or repeatedly failing dump trailer cylinders? Our telescopic cylinders for Appalachian trailers are rebuilt and redesigned with wear bands, urethane U-seals, and longer glands for better stability, reduced leaks, and longer life. Buy a ready-to-install unit, return your core, and get back to work fast.
Description
Telescopic Cylinders for Appalachian Dump Trailers
Also compatible with other makes
Stop fighting leaks and repeat failures
Do your dump trailer cylinders leak oil?
Have you paid for rebuilds that did not last?
There is a better approach.
These are not simply rebuilt cylinders. Each unit is professionally re-engineered and redesigned to correct the common weaknesses that lead to leaks, instability, and premature failure.
Our Rebuild & Redesign Process
Every cylinder we supply goes through a detailed rebuild that includes critical engineering upgrades:
1. Wear Bands Added to Every Section
We install a wear band (bearing) on each stage of the cylinder.
Many older designs lacked wear bands, allowing excess clearance between moving components. Adding wear bands:
-
Reduces internal play
-
Improves alignment
-
Minimizes metal-to-metal contact
-
Extends service life
Result: A tighter, more controlled fit.
2. Urethane U-Seals Instead of V-Packings
We replace traditional V-packings with high-performance urethane U-seals.
Benefits include:
-
Superior sealing performance
-
Better resistance to pressure fluctuations
-
Increased durability
-
Reduced leakage risk
Result: More reliable sealing under real-world conditions.
3. Extended-Length Glands
Each gland is engineered 1 inch longer.
This increases overlap between cylinder sections, making the cylinder more stable and solid when fully extended.
Benefits include:
-
Greater rigidity
-
Reduced deflection
-
Improved structural support
Important note:
Because of the increased overlap, the total extended length is reduced by approximately 3 inches.
How itWorks
We operate on a rebuilt cylinder exchange basis:
-
We sell you a rebuilt & redesigned cylinder
-
You return your old cylinder (core)
-
Your core is rebuilt for the next customer
This system allows:
-
Faster turnaround
-
Consistent availability
-
Cost-effective solutions
-
Reduced downtime
The Outcome
Our rebuilt & redesigned cylinders deliver:
-
Reduced leakage issues
-
Improved stability
-
Longer service life
-
Greater confidence under load
