Reverse kingpin trucks are common on longboards; traditional kingpin trucks are common on street skateboards and some compact cruisers. Match axle width to the deck and intended setup.
Longboard trucks differ in geometry and fit. Reverse kingpin (RKP) trucks are common on longboard setups, while traditional kingpin (TKP) trucks are common on street skateboards and compact cruisers. The right choice depends on deck width, wheel clearance and the way you want the board to turn.
| Truck style | Typical fit | What to verify |
|---|---|---|
| RKP | Many longboard and carving decks | Axle width, baseplate angle and wheel clearance |
| TKP | Street boards and some compact cruisers | Axle width, riser needs and deck shape |
| Brand-specific geometry | Specialized boards and setups | Manufacturer compatibility and recommended components |
Do not choose by kingpin orientation alone. Match the truck axle width to the deck maker’s recommendation, then check wheel diameter, wheelbite clearance, risers and mounting-hole pattern. Manufacturer size charts may list hanger, axle or overall width differently, so compare like measurements.
A carving setup may value a turnier feel, while a stable downhill-oriented setup may use different geometry and angles. This is a setup choice rather than a universal ranking. Inspect the exact product specifications for baseplate angle, hanger width and bushings, and make sure the board can accommodate the truck without wheel contact.
For a cruiser, consider deck length, wheel size and where you will ride. A compact deck with TKP trucks may be convenient for short trips; many longer boards use RKP designs. See longboard vs cruiser vs skateboard for board shapes and intended use, then compare deck fit in skateboard deck sizing.

Common questions
What is an RKP truck?
A reverse kingpin truck places the kingpin in the opposite orientation to a traditional skateboard truck; check the maker’s product description.
Are TKP trucks good for longboards?
They can suit compact cruiser or street-style boards, depending on deck width and desired handling.
How wide should longboard trucks be?
Choose axle width to match the board maker’s guidance and deck width; do not rely on the hanger width alone.
