Independent MID 139mm Polished Skateboard Trucks Set of 2 with Inverted Kingpin for Street, Tricks, and Skatepark
More control, smoother grinds, and the trusted quality of Independent! The Independent MID 139mm Polished skateboard trucks combine the legendary Independent geometry with a lower profile and a smart inverted kingpin. With a height of just 52 mm and a total hub width of 8.0 inches, these trucks are ideal for technical street tricks, grinds, and the skatepark. You receive a complete set of 2 trucks.
MID geometry: lower, more direct, and more control
The Independent MID trucks have a height of 52 mm, placing them lower than the traditional Independent High trucks. The lower center of gravity ensures a direct riding feel and a stable base during technical tricks, manuals, and landings.
Furthermore, the modified geometry ensures a favorable contact angle between the deck and the ground when using the nose or tail. This makes these trucks particularly interesting for skaters who like to perform ollies, kickflips, and other technical tricks.
Inverted kingpin for extra clearance during grinds
An important feature of the Independent MID series is the inverted Grade 8 kingpin . With this construction, the kingpin protrudes less than on traditional skateboard trucks. This gives you more clearance during grinds and reduces the chance of the kingpin catching on curbs, ledges, and rails.
The kingpin is adjustable with a 9/16 inch wrench or 5.5 mm Allen key . This allows you to easily adjust the steering behavior to your personal preference.
139mm trucks for skateboard decks of approximately 8.0 inches
The Independent MID 139 has a total hub width of 8.0 inches (203 mm) and a hanger width of approximately 139 mm. This size fits perfectly on skateboard decks with a width of 7.875 to 8.125 inches .
These trucks form a great combination, especially with an 8.0-inch skateboard deck. The wheels align well with the width of the deck, resulting in a balanced skateboard setup.
Strong aluminum construction with chromoly steel shafts
Independent is known for its robust skateboard trucks. The MID 139 features an A356 T6 aluminum hanger and baseplate . This aluminum alloy combines strength with a relatively low weight and offers the familiar grind feel of Independent.
The SCM435 chromoly steel axle is designed to withstand the loads of intensive skateboarding. This makes these trucks suitable for regular use on the street and in the skatepark.
Which wheels fit Independent MID trucks?
Skateboard wheels up to 53 mm are recommended for the Independent MID 139. Thanks to the lower truck height, your skateboard remains compact and responds directly to steering movements.
Do you want to use larger wheels? Then riser pads may be necessary to maintain sufficient clearance between the wheels and the deck and prevent wheelbite.
For street, grinds, and skatepark
The combination of a low profile, inverted kingpin, and strong construction makes the Independent MID 139mm particularly suitable for technical skateboarders. Whether you are practicing flip tricks, grinding over ledges, or riding through the skatepark, these trucks offer a versatile foundation for your skateboard.
Moreover, thanks to the original Independent bushings, the trucks retain the characteristic smooth steering behavior for which the brand is known.
