A REVOLUTION IN RKP TRUCK TECH

Stabilized Geometry with No Added Parts

Aeon bushings pair to form a cylindrical hollow that locks around barrel-shaped hanger elements – a true bearing with no added parts. This patented design forces the hanger to rotate inside the tubular channel in perfect alignment with the pivot axis. Eliminates slop, aligns and stabilizes geometry without the downsides of support pins, spherical bearing inserts, or hanger plugs. Quick response from center and noticeably smoother, cleaner turns – even at very deep lean angles, which destabilize the steering of ordinary RKP trucks (including those claiming geometry steeper than 45-degrees).

Advanced Control
Beyond barrel vs. cone: Aeon bushings have a wide hexagonal shape and tapering sides, for a 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 & Affordable

Optional hollow axles, elegant body sculpting, and the first-ever hollow pivot channel (extending into bearing section).  Precision engineering is what counts, and the Aeon packs it 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 boardside bushing and baseplate – no washer needed. Faced hangers for perfect interface with inside bearings. Top of baseplate sloped for flush contact with deck concave when dropthrough-mounted. (Nut seats kept flat.)

Axle Height, Axle Offset, and Roll Center

Axle Height: 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
Roll Center: 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-degree truck at the nose and a 30-degree truck at the tail, with stiffer bushings at the tail than at the nose. Use two 45-degree trucks on symmetrical (twin-tip) freeride decks. Use stiffer bushings if you’re heavier and/or taller than average, softer bushings if you’re lighter and/or less tall.

    These freakin trucks are so responsive. Even better at High Speeds. The Aeon 45 degree in the front is perfect match to the way the 30 degree cuts in and holds a tight response. Running with Hotspots Blackops 77A wheels and TEKTON 6 ball bearings.

Truck Axle Tolerance

Seismic axles (both G5 and Aeon) are manufactured to be 7.95mm in diameter, with a small negative-only tolerance. Racing truck makers who advertise “true 8.0mm axles” generally follow a similar specification. Average brands use 5/16-inch (7.9375mm) axles.

The inner race of standard wheel bearings has a diameter of 8.0mm, with a small manufacturing tolerance. Truck axles need to have a diameter slightly smaller than that, or else some bearings may not fit or even get stuck.

Truck Hole Pattern

Seismic trucks (both G5 and Aeon) support both “Old School” and “New School” mounting hole patterns. In the case of the G5, this was a significant engineering challenge given the truck’s unique structure.

The Old School mounting hole pattern has holes that are 2.50″ (63.5mm) center-to-center longways. In the New School hole pattern, that distance is only 53.5mm (2.11″). Both patterns have holes that are 1.625″ center-to-center sideways.
