WoodSplitPro Hydraulics Upgrade Kit Review: Is It Worth the Performance Boost?
Firewood processing is a demanding task, and even the most robust machines can benefit from a targeted upgrade. The WoodSplitPro Hydraulics Upgrade Kit promises to transform a standard firewood processor into a high-output workhorse by improving cycle speed and splitting force. This review examines whether this aftermarket kit delivers tangible gains for both hobbyists and commercial operators, weighing cost against real-world performance.
What Does the WoodSplitPro Hydraulics Upgrade Kit Include?
The kit is designed to retrofit most WoodSplitPro models from 2018 onward, targeting the hydraulic circuit that governs the splitter wedge and conveyor system. According to the manufacturer’s specifications, the package includes a high-flow pump rated at 22 GPM (gallons per minute), a 4-way control valve with integrated relief, hardened steel hoses with JIC fittings, and a billet-machined cylinder with a 4-inch bore and 24-inch stroke. A mounting bracket kit and step-by-step wiring harness are also supplied.
Notably, the kit does not include a new engine or hydraulic fluid reservoir, meaning users must ensure their existing power plant can handle the increased flow. The complete assembly weighs approximately 68 pounds and requires basic mechanical skills for installation—typically 3–5 hours for an experienced operator. The retail price in the United States is $1,950, while in Canada it starts at CDN $2,650, factoring in exchange and shipping.
How Much Faster Is the Cycle Time After Installation?
Performance gains are the core selling point. Independent testing by Firewood Equipment Review measured cycle times on a standard WoodSplitPro unit before and after installation. The stock machine managed a 4-second wedge advance and a 3-second return, yielding a total cycle of 7 seconds per split. With the upgrade kit, the wedge advanced in 2.2 seconds and returned in 1.5 seconds, bringing the total to 3.7 seconds—a 47% reduction in cycle time. This translates to roughly 970 splits per hour versus 514, a meaningful boost for commercial operators processing cord after cord.
However, real-world conditions vary. Wood species, log diameter, and hydraulic fluid temperature all affect performance. On harder woods like oak or hickory, the speed advantage narrows slightly due to increased resistance, but the kit still shaves off 2–3 seconds per split compared to stock. For a busy operation running 8 hours a day, this could mean an extra 2–3 cords processed daily, significantly improving throughput without buying a new machine.
Does the Upgrade Compromise Reliability or Safety?
Any hydraulic modification raises valid concerns about component stress. The WoodSplitPro Hydraulics Upgrade Kit uses a reinforced cylinder with dual sealing rings and a heavier-duty rod, rated for 3,500 PSI maximum operating pressure—200 PSI higher than stock. The pump is gear-type, known for durability, and the valve includes a pressure relief set at 3,200 PSI to prevent overloading the frame or engine.
That said, users must adhere to strict WoodSplitPro Safety Tips for Beginners and Pros to avoid injury. The increased cycle speed means the wedge moves faster, demanding sharper attention near the splitter area. Anecdotal reports from early adopters note no catastrophic failures, but two users on online forums mentioned hose chafing against sharp edges on the frame. The kit includes nylon abrasion guards, but double-checking routing during installation is wise. Overall, the upgrade appears mechanically sound for operators who follow torque specifications and use proper hydraulic fluid (ISO 32 or 46, depending on climate).
How Does the Cost Compare to Buying a New Processor?
At $1,950 USD or CDN $2,650, the WoodSplitPro Hydraulics Upgrade Kit sits in a mid-range investment territory. A brand-new mid-tier firewood processor—such as the WoodMaxx WM-8T or Fransgård TC-10—typically ranges from $4,000 to $8,000 USD. For owners of a paid-off WoodSplitPro machine, the upgrade represents roughly 25–40% of a replacement cost, offering substantial performance uplift at a fraction of the price. However, if your current processor has significant frame wear or engine issues, investing in a new unit may be more prudent.
| Option | Approximate Cost (USD) | Throughput Gain | Installation Effort | Warranty |
|---|---|---|---|---|
| WoodSplitPro Hydraulics Upgrade Kit | $1,950 | 40–50% faster cycle | 3–5 hours DIY | 2 years (limited) |
| New WoodMaxx WM-8T processor | $4,200 | Baseline (similar to stock) | Ready to run | 3 years |
| New Fransgård TC-10 processor | $5,500 | Slightly higher output | Professional setup recommended | 1 year (parts only) |
| New Timberwolf TW-PRO processor | $7,800 | Commercial-grade speed | Professional setup recommended | 2 years |

What Are the Installation Steps and Challenges?
Installing the WoodSplitPro Hydraulics Upgrade Kit requires a methodical approach. First, drain the existing hydraulic fluid and disconnect the battery. The old pump mounts on the engine PTO shaft; remove it along with the stock hoses. The new pump bolts directly in place using the supplied bracket, but some users have reported minor alignment issues on 2019–2020 models where the frame tab thickness varies by 1/8 inch. A file or grinder can resolve this quickly.
Next, route the high-pressure hoses from the pump to the control valve, which mounts near the operator station. The kit includes a new valve handle for easier modulation. The cylinder replacement is straightforward: unbolt the old cylinder, install the new one with the included pins and clips, then connect the hoses using thread sealant on the NPT fittings. Finally, fill the reservoir with fresh hydraulic fluid (approximately 3.5 gallons), bleed the system by cycling the wedge several times, and check for leaks. A torque wrench is essential for the cylinder mounting bolts to avoid stress fractures.
For safety, wear gloves and eye protection throughout. If you are new to hydraulic systems, read WoodSplitPro Safety Tips for Beginners and Pros before beginning. Most DIYers complete the job in a single afternoon, though a second person is helpful for aligning hoses.
What Owners Say About Real-World Performance?
Feedback from owners who have installed the kit is largely positive but not without nuance. On forums and product review sites, approximately 78% of users rate it 4 or 5 stars, citing noticeable speed improvements and smoother operation. Many note that the increased force helps split knotty or stringy wood that previously bogged down the stock machine. For example, a logger in Oregon processing Douglas fir reported averaging 1.5 cords per hour after the upgrade, up from 0.9 cords per hour previously.
Criticisms focus on a few areas. Some users report that the pump emits a higher-pitched whine at full flow, which can be annoying during long sessions. Others mention that the control valve handle is stiff initially, requiring a break-in period of about 50 cycles. Additionally, the instruction manual has been called “sparse” by several owners, though video tutorials from WoodSplitPro address this. Overall, the consensus is that the kit delivers on its promises for operators who are comfortable with mechanical work and willing to invest in quality hydraulic fluid.
