Independent Trucks Size Chart & Sizing Guide
Jan 09, 2025
Choosing the right Independent trucks starts with one measurement: your deck width. For the most balanced setup, match the truck axle as closely as possible to the widest part of your deck. A small amount of overhang or underhang is workable, but the axle should generally sit close to flush with the deck edges.
If you just need the answer, use the chart below. The familiar Independent numbers—129, 139, 144, 149 and 159—are model sizes, not axle widths in millimetres.

- 8.0-inch deck: Independent 139
- 8.25-inch deck: Independent 144
- 8.5-inch deck: Independent 149

- 9.0-inch deck: Independent 159 or 169, depending on whether you prefer a slightly narrower or wider setup
- 10-inch deck: Independent 215
How to Measure Your Deck Width
Measure straight across the widest part of the deck from edge to edge. Use the manufacturer’s listed width when it is available. You do not need a perfect match: a difference of roughly one-eighth of an inch is rarely noticeable, and some skaters intentionally run slightly narrower trucks for clearance or slightly wider trucks for stability.
Stage 11 vs Stage 4 Sizing
Independent Stage 11 Standard trucks are 55 mm high and are available in sizes including 129, 139, 144, 149, 159 and 169. Hollow, Forged Hollow and Forged Titanium versions change the construction and weight, but the axle-width recommendation stays the same for a given size.
Stage 4 uses a different set of model numbers—136, 146, 151 and 166—so always check the axle width rather than assuming a Stage 4 number matches a Stage 11 number.

Truck Width and Skate Style
A close deck-to-axle match is the best starting point for street, park and transition skating. Slightly narrower trucks can feel quicker and keep the wheels tucked under the deck; slightly wider trucks can add stability and give you more axle to lock onto grinds. Neither is automatically better—the right choice comes down to your deck shape and how you like your setup to respond.
Truck height matters separately from width. Standard Stage 11 trucks are 55 mm high, Forged Stage 11 models are 53.5 mm, and Independent Mid trucks sit lower. Larger wheels may need extra clearance or riser pads to reduce wheel bite.

Independent Truck Sizing FAQs
What size Independent trucks fit an 8-inch deck?
Independent 139 trucks have an 8.0-inch axle and are the standard match for an 8-inch deck.
What size Independent trucks fit an 8.25-inch deck?
Independent 144 trucks have an 8.25-inch axle and are the closest match. A 139 or 149 can also work if you intentionally prefer a slightly narrower or wider setup.
What size Independent trucks fit an 8.5-inch deck?
Independent 149 trucks have an 8.5-inch axle and are the standard match for an 8.5-inch deck.
Do Independent truck numbers equal millimetres?
No. Numbers such as 139, 144 and 149 are Independent model sizes. Use the axle-width column in the chart to match them to your deck.
Should skateboard trucks be the same width as the deck?
That is the best starting point. Keeping the axle close to the deck width gives a predictable balance of stability, turning and wheel clearance.
When should I replace bushings or other truck parts?
Replace bushings when they are cracked, permanently compressed or no longer return the truck to centre. Replace damaged pivot cups, kingpins or axles when wear begins to affect steering or safety.
