A strong log-splitter ram matches your machine’s mounting style, bore, stroke, and hydraulic connections; that makes these cylinders useful for owners replacing a worn unit or configuring a splitter. This roundup compares ten double-acting options, from 4-inch-bore, 24-inch-stroke cylinders for 22–28-ton machines to 5-inch-bore models and a 30-inch-stroke cylinder. Several products target specific MTD, Cub Cadet, or Dirty Hand Tools applications, while others list broader compatibility.
The distinction matters: a cylinder with the right bore can still fail to fit if its clevis, trunnion, bolt-hole spacing, or ports differ. Use the listed dimensions and replacement references to narrow the field, then confirm your splitter’s original cylinder and mounting measurements before ordering.
Reliable Aftermarket Parts 718-0306 is the strongest general replacement pick because it lists a 4-inch bore, 24-inch stroke, 3500 PSI double action, and compatibility with several 25–28-ton MTD and Cub Cadet splitters, plus Dirty Hand Tools, TSC, County Line, Huskee, Oregon, SpeeCo, and SplitMaster models using a matching 4×24 double-clevis cylinder. Choose it only if your original cylinder matches its 34.5-inch bolt-hole spacing, 1/2-inch NPT ports, and mounting details; listed brand compatibility is not a substitute for checking fit.

9. Magister Hydraulics 5×30
- Weight: 103 lb
- Dimensions: 47 x 7 x 7 in
Best for: Long-stroke splitter ram.
Why it ranks #9: Its 5-inch bore and 30-inch stroke distinguish it for buyers needing more travel, though the supplied data gives fewer mounting and pressure details.
A 30-inch stroke is the key distinction of this Magister Hydraulics cylinder, offering a longer listed travel than the 24-inch-stroke options in this roundup.

10. AGKNX 5-Inch Cylinder
- Weight: 80 lb
Best for: High-pressure clevis-mount ram.
Why it ranks #10: It describes a 5-inch, 24-inch-stroke double-acting clevis cylinder, but its 4000 PSI maximum and broad OEM fit need careful machine verification.

Double-acting ports provide forward and reverse motion, while clevis mounts at both ends support replacement of many OEM cylinders using that mounting style. The replaceable seals offer a service-related feature, and the stated force figures are tied to specific operating pressures: approximately 35 tons at 3,500 PSI and up to 39 tons at 4,000 PSI maximum. Its 5-inch bore and 24-inch stroke remain essential dimensions to match against the splitter.
- 5-inch bore and 24-inch stroke
- Replaceable seals
- Clevis mounts at both ends
- Stated force figures at 3,500 and 4,000 PSI
- The stated maximum operating pressure is 4,000 PSI, so system pressure must suit it.
Skip it if you need a 30-inch stroke; Magister Hydraulics’ B08W8H2GF2 lists that longer travel.
This AGKNX ram suits buyers seeking a 5-inch-bore, 24-inch-stroke double-acting cylinder with replaceable seals. Its listed pressure and force figures make matching the splitter’s hydraulic system especially important before selecting it.

View on AmazonAvoiding a fit mismatch during replacement
A matching bore and stroke do not guarantee that a replacement cylinder will bolt onto your splitter. Mount geometry is a major compatibility trap in this set: ToolTuff’s 4.5-inch-bore cylinders use trunnion mounts, while several 4×24 replacements use clevis mounting. Even within clevis designs, the Reliable Aftermarket 718-0306 lists 34.5-inch bolt-hole spacing and 1-1/8-inch clevis mounting holes; the ROP Shop Universal 4×24 also lists 1-1/8-inch clevis holes but has its own port and rod details.
Before replacing a cylinder, record its retracted and extended lengths, mount style, pin-hole diameter, port thread, and spacing. Compare those measurements with the product listing and your splitter’s parts reference.
Treat brand names as clues, not proof of fit, especially when the listing says compatible with many models.
Why bigger bore is not a simple upgrade
A larger bore can increase cylinder force at a given pressure, but it also changes the demands on the hydraulic system. These listings range from 4-inch bore to 4.5-inch and 5-inch bore; AGKNX specifically claims about 35 tons at 3500 PSI and up to 39 tons at 4000 PSI, while AMRAP lists 3500 PSI for its 5-inch cylinder. Those figures do not establish that a particular splitter’s pump, valve, frame, or hoses can safely support the cylinder.
A larger cylinder can also require more oil volume to travel the same stroke, affecting cycle time with a given pump. For a replacement, matching the original bore and system rating is usually the safer starting point.
Consider a different bore only after confirming the machine’s hydraulic and structural limits.
How to Choose a Log Splitter Cylinder
Bore, stroke, and rod dimensions
Start by matching your original cylinder’s bore, stroke, and rod rather than choosing the largest listed size. This selection ranges from 4-inch-bore, 24-inch-stroke cylinders through 4.5-inch-bore, 24-inch-stroke trunnion models to 5-inch-bore cylinders, including a 30-inch stroke option. Several 4×24 listings specify a 1-3/4-inch rod, while Sunluway and AMRAP list a 2-inch rod.
A 4×24 model favours owners replacing a common 22–28-ton configuration with matching dimensions; a 5-inch bore or 30-inch stroke favours only a machine designed to use those dimensions. Check retracted length and available frame clearance too; a nominally matching stroke alone does not ensure the cylinder fits.
Mounting style and connection details
Choose a cylinder whose mounts and ports match your splitter, because mismatches can prevent installation even when the bore and stroke look right. The ToolTuff models are trunnion mount; many other options use clevis mounting. Reliable Aftermarket 918-0769A lists 1/2-inch NPT ports and 1-1/8-inch clevis holes, while the ROP Shop 4×24 listings specify a 3/4-inch NPT port.
ToolTuff’s 4.5-inch trunnion cylinder has a 1/2-inch NPT fitting at one end and a 1/2-inch JIC fitting at the other; its other model adds a valve bracket. Buyers replacing a trunnion-mounted MTD-family unit should compare those details, while clevis-cylinder buyers should verify pin dimensions, spacing, and thread type.
Machine tonnage and replacement fit
Use the splitter’s model and rated tonnage to identify plausible replacements, then confirm the original part number and physical measurements. Listings cover different use cases: ROP Shop’s universal 4×24 is for 22–25-ton machines, Reliable Aftermarket 718-0306 lists 22–28-ton fit across several brands, and ToolTuff’s 4.5-inch trunnion products specify 27–30-ton units. The Sunluway cylinder names brands including CountyLine, Huskee, MTD, Oregon, and SpeeCo, while the 918-0769A listing specifically identifies MTD and Cub Cadet.
Buyers replacing a named OEM unit should favour a listing that gives the matching part number and mount style; owners of other models should verify the measurements rather than relying on a broad universal-fit description.
Which Log Splitter Cylinder Should You Choose?
For a common 4×24 double-clevis replacement across several named brands, choose Reliable Aftermarket 718-0306, after checking its 34.5-inch bolt-hole spacing and ports against your machine. If your splitter needs a 5×24 cylinder with 3500 PSI and 1/2-inch NPT ports, AMRAP Hydraulics 5×24 gives the clearest listed match. For 22–25-ton machines with a matching 3/4-inch NPT setup, consider ROP Shop Universal 4×24.
Choose ToolTuff MTD Trunnion Cylinder for a 27–30-ton trunnion-mounted unit requiring its listed NPT/JIC fittings; choose ToolTuff 918-04713 Trunnion if the valve bracket is needed. Magister Hydraulics 5×30 is for a machine built around that longer stroke.
In every case, compare mount type, dimensions, ports, and OEM reference before ordering.
Frequently Asked Questions
How do I measure a log splitter cylinder before ordering a replacement?
Measure the original cylinder’s bore, rod diameter, stroke, and mounting dimensions, including the distance between mounting holes. Check its port size and thread type, mount style, and overall fit in the splitter. Compare those details with the replacement listing and your machine’s OEM reference; similar tonnage or brand compatibility alone does not confirm a match.
Can a cylinder with a larger bore be used with my existing pump and valve?
Not automatically. A larger bore can produce more force at the same hydraulic pressure, but it also requires more oil to move the piston through a given stroke, which can affect cycle speed. Confirm that the pump, valve, pressure rating, ports, and mounting arrangement suit the cylinder before replacing it.
What causes a replacement log splitter cylinder to bind or leak?
A mismatch in mounting dimensions or alignment can make a cylinder bind, while incompatible ports or fittings can leak. Damaged seals or contamination can also contribute to leaks or poor movement. Before use, compare mount type, dimensions, port threads, and fittings with the original, and inspect the installation for damage or misalignment.
Should I choose a 24-inch or 30-inch stroke cylinder?
Match the stroke to the splitter’s original cylinder and available frame travel. A 30-inch stroke is not a direct substitute for a 24-inch stroke unless the machine’s geometry and operating range accommodate it. Check the OEM reference, retracted and extended fit, and mounting dimensions before choosing a different stroke.
How do I check whether the replacement cylinder’s ports will fit?
Compare both port thread type and size with the original cylinder and the splitter’s hoses or fittings. For example, the listed AMRAP 5×24 option specifies 1/2-inch NPT ports, while the ToolTuff trunnion listings refer to NPT/JIC fittings. Confirm the exact connection required by your machine rather than relying on a broad compatibility claim.
Final Words
For a common 4×24 double-clevis replacement, the Reliable Aftermarket 718-0306 is the strongest general pick, provided its 34.5-inch bolt-hole spacing, 1/2-inch NPT ports, and mounting details match your splitter. Choose the AMRAP 5×24, ROP Shop 4×24, or a ToolTuff or Magister option only when its listed bore, stroke, fittings, and mount suit your machine. Verify dimensions and OEM references before ordering.
