SKU: AEON_BUSHINGS Categories: , , ,

Bushings for Seismic® Aeon™ Trucks
Available in six (6) color-coded hardnesses, including NEW 78A pink and 82A yellow.
Self-lubricating formula to prevent squeaking.
Price is for a single matched pair of one (1) Board-Side and one (1) Road-Side bushing – enough for one (1) truck.

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.

Precision Fit
• Custom contouring creates mechanical lock between Board-Side (BS) bushing and baseplate – no washer needed.

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 tight 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.

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.
