If there's one spec that changes the character of a track system more than anything else, it's lug height. We have three heights in our lineup. Each one exists for a specific reason.
1" lug — the all-rounder
This is the lug on the WR4 and XR4. It delivers solid traction on regular snow and hard surfaces, with minimal vibration and a driving feel close to tires. Most of our customers end up with this lug height.
That doesn't mean it's the 'beginner' lug — it means it makes the most sense in the widest range of conditions. Groomed trails, forest roads, typical seasonal snow — the 1" is the right call.
1.5" lug — for deep snow
This is what separates the WR4X from the WR4. You gain traction and flotation in deep snow and soft terrain; you give up some comfort on hard surfaces. That's an intentional trade-off.
The WR4X is a specialized tool. It excels in the conditions it was built for. When choosing between the two, think about your hardest terrain — not your average terrain. That's where lug height makes the real difference.
2.5" lug — for extreme conditions
This is the option on the HD4S for serious conditions. 3-4 feet of snow, waterlogged terrain, unstable ice. At 2.5", the traction is unmatched — but it's a heavy system built for heavy machines.
Not for everyone. But for hunters in remote territory, operators in northern terrain, trappers — there's nothing else like it.
Practical rule: choose your lug height based on your hardest terrain, not your average terrain.
What not to do
Don't go for the tallest lug 'just to be safe.' A 2.5" lug on hard-packed trail is uncomfortable and wears fast. Lug height isn't about maximum performance — it's about matching the terrain.
