Seismic® Aeon™ 45-degree Truck
180mm sparkle black hanger, 45-degree silver baseplate, high-rebound 90A blue bushings
Price is for a single truck. Order two (2) trucks for one skateboard.
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.
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 deep lean angles that destabilize the steering of ordinary RKP trucks.
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.)
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.
