Kimpex HD4 vs Soucy HD4Pro

Clear up the names first

Kimpex Commander HD4

A heavy-duty 4-season UTV track from Kimpex, part of the Commander family (which also includes the WSS4). The HD4 uses a conventional slide-guided design with a tubular steel frame, 15" all-season sprocket, and dual-ball-bearing wheels. Available in both 4-hole and 5-hole wheel patterns, and shares fasteners with the WSS4 for parts compatibility.

Soucy HD4Pro

A heavy-duty 4-season UTV track from Soucy Track— a different company entirely (Quebec-based, rubber-track manufacturer since 1978). The HD4Pro's defining feature is its wheel-guided design — it uses internal wheels instead of plastic slide guides to keep the track aligned. 4,000 lb load capacity, designed for no-modification install on the host UTV.

So: same approximate naming, completely different products, completely different engineering, completely different companies. With that cleared up — here's the actual comparison.

Side-by-side

Wheel-guided vs slide-guided — the actual engineering difference

Slide-guided (Kimpex HD4, and most of the industry)

The standard approach. Plastic slide guides ride along the rail to keep the rubber track centered. The plastic is a deliberate consumable — it wears, gets replaced. Heavy mud and dry hard-ground use shortens slide-guide life; snow-only use extends it.

The upside: well-understood engineering, easy parts sourcing, decades of field data. The downside: replacement cycle that costs money and shop time every few seasons.

Wheel-guided (Soucy HD4Pro, unique in UTV)

Soucy uses internal wheels to guide the track instead of plastic slides. The result: no slide-guide replacement cycle. For high-hour year-round operators, this can mean meaningful savings in maintenance time and parts cost over five seasons.

The tradeoff: less common engineering means fewer field-tested decades behind it (though Soucy has done this approach for years now, and the HD4Pro is field-proven in its own right). It's also a single-vendor design — only Soucy parts fit.

Where the Kimpex HD4 wins

• Hardware compatibility with WSS4. If you might also own a WSS4 (or know other Kimpex owners), parts and service simplify.
• 5-hole wheel pattern support. Explicitly built in. Some 5-hole UTVs are easier on the Kimpex side.
• Conventional service ecosystem. Standard slide-guide maintenance is well-understood and parts are widely available.
• Kimpex dealer network. Strong in Canada and northern US.

Where the Soucy HD4Pro wins

• No slide-guide replacement cycle. The clearest ownership advantage. High-hour year-round operators report this saves real money over 5–7 seasons.
• Multi-level bearing seal design.Premium seals against water and dirt. Mud and water intrusion is a real failure mode in this category; the HD4Pro's design helps.
• No vehicle modification. Fully reversible to tires. Real benefit if you might sell the UTV and want to retain resale value.
• Engineering pedigree. Soucy has been making rubber tracks since 1978, including OEM supply contracts. Quiet credibility.

Parts ecosystem matters more than you think

Five years from now, when you need bearings, idlers, or (for the Kimpex) slide guides, the question isn't which track was “better” in 2026. It's which brand's parts you can get to your shop in 48 hours.

Practical check: call your local powersports dealer. Ask which brand they stock parts for. The answer often tells you more about which to buy than any spec comparison.

Decision framework

1. Hate maintenance / high-hour operator? HD4Pro — wheel-guided removes a consumable.
2. 5-hole wheel pattern UTV? Verify HD4Pro compatibility; HD4 explicitly supports it.
3. Already running a Kimpex WSS4? HD4 — shared hardware family.
4. Plan to sell the UTV in a few years? HD4Pro — no-modification install preserves resale.
5. Canadian buyer with strong Kimpex dealer? HD4.
6. Local dealer stocks one but not the other? The one your dealer stocks.
