Patent Truck Turn Technology

Beyond Barrel vs. Cone: Aeon bushings have a wide hexagonal shape and tapering sides.  Creates smooth, intuitive resistance profile through a larger steering range.

  • Description

    Cylindrical Bearing Built Directly Into Bushing-Hanger Interface – A Revolution in RKP Truck Engineering!
    • Concave channels (“races”) on bushing faces wrap around “rollers” built in to hanger bushing seats.
    Patented Aeon “TrueTurn” tech forms working cylindrical bearing with no added parts. (See exploded view in second image.)
    • Centers and guides hanger rotation, in exact alignment with pivot axis – without the downsides of support pins, spherical bearing inserts, or hanger plugs.
    • Eliminates slop, significantly stabilizes geometry even at deepest lean angles – so much so that 45° Aeons turn as much as most ordinary RKP trucks that claim steeper geometry.

    Advanced Control
    Beyond Barrel vs. Cone: Aeon bushings have a wide hexagonal shape and tapering sides.  Creates smooth, intuitive resistance profile through a larger steering range.
    • Tall but not too tall, for deep turns with no dive.
    • Self-lubricating formula to prevent squeaking.

    Lightweight and Affordable
    • Elegant body sculpting and the first-ever hollow pivot channel (extending into bushing seat area).
    • Precision engineering in a moderately-priced cast design.  (CNC body parts add high cost with no guarantee of high performance.)

    Precision Fit
    • Custom contouring creates mechanical lock between Board-Side (BS) bushing and baseplate – no washer needed.
    • Faced hangers for perfect interface with inside wheel bearings.
    • Top of baseplate sloped for flush contact with deck concave when dropthrough-mounted. (Nut seats kept flat.)

    Axle Height
    30° Model: 60.4mm / 2.38 inches from baseplate bottom to axle midpoint (39.7mm / 1.56 inches when hanger is flipped)
    45° Model: 60.3mm / 2.37 inches from baseplate bottom to axle midpoint (34.8mm / 1.37 inches when hanger is flipped)

    Axle Offset (Rake)
    9.0mm / 0.35 inches (both 30° and 45° models)

    Roll Center

    30° Model: 10.4mm / 0.41 inches above axle midpoint (same distance below axle midpoint when hanger is flipped)
    45° Model: 12.7mm / 0.50 inches above axle midpoint (same distance below axle midpoint when hanger is flipped)
    More Axle Offset (or Rake) pushes the Roll Center higher (towards the deck), resulting in quicker lean response and better wheel traction.  Less Axle Offset (or Rake) leaves the Roll Center lower (near the axles), resulting in better lean control and stability.

    General setup suggestions
    For optimal traction, power, and control, we usually suggest a 45° truck at the nose and a 30° truck at the tail, with stiffer bushings at the tail than at the nose. Use two 45° trucks on symmetrical (twin-tip) decks. Use stiffer bushings if you’re heavier and/or taller than average, softer bushings if you’re lighter and/or less tall.
