Seismic® Aeon™ 155mm Truck
155mm matte black hanger on matte black baseplate (choice of 30° or 45° geometry). Assembled with high-rebound bushings. Hanger space-able to 160mm+. (High-precision axle spacer kit coming soon.)
Price is for a single truck. Order two (2) trucks for one skateboard.
Noticeably cleaner, deeper turns • Quick response from center • Smoother, more intuitive resistance profile • Affordable price!
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.
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.)
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.
• For comfortable, surfy, cruising-style steering response, use Boardside and Roadside bushings of the same duro. For strictest, most accurate race-style steering response, use harder Boardside bushings and softer Roadside bushings – especially with trucks wedged steeper than 45°, and with DH and Fast Freeride setups using narrower hangers and split geometry. (Example: blue 90A bushing Boardside and yellow 82A bushing Roadside on your FRONT truck.)
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.

Such a responsive pair of trucks. With the 45 degree
up front and this the 30 degree truck cutting
in behind and holding such a tight response.
This is the most comfortable truck yet. So responsive
to my everything. Seismic nails it with this truck for a
F’n Killer Downhill Experience.

I’ve been longboarding for some time now but have only really gotten into it this year. I’ve had the pleasure of riding on a wide variety of reverse kingpin trucks and now seismic trucks, in particular the Siesmic Aeon 30-degree trucks. I’d have to say that Seismic Aeon 30-degree trucks are absolute magic. I’ve got a pair set up on my freeride board. It has a deep, surfy feel with no slop. Seismic Aeon trucks are very stable at speed and in deep turns. I was originally going to get a Seismic Aeon 45-degree truck on the front and a 30-degree truck out back, but so far I’m really happy with the turn of two 30-degree trucks. The positive rake in the trucks is just right. The hexagonal Seismic bushings are spot-on with no squeak. I usually ride very hard bushings (95-98 duro) in double barrel configuration on my other trucks, but I find I’m very stable on the 94 duro that comes with Seismic Aeon 30-degree trucks with a less tight setup than I would usually run. It makes turning more fun. Well done, Seismic, for making these trucks.

Got the Seismic Aeon 45° Quick-turn truck with blue 90A-durometer bushing for use as a front RKP truck and the Aeon 30° Stable-turn truck with red 94A-duro bushing for use as a rear RKP truck, and they are just an amazing piece of engineering. Especially love how their complementary design results in equal (ok, within 100 microns, lol) axle height when the two are top-mounted in spite of their differing baseplate angles; how the hangers are machined to be precisely faced toward the included speed rings; how the unique hexagonal bushings are designed to fit seamlessly into the shaped hanger with the impossibly tight tolerances of Incan mortarless brickmasonry; and how the hangers are designed to be flippable (just like the first RKP trucks I ever owned, Bear 852 Grizzlies, though tbh I can’t imagine a situation where I would ever need or want to run these trucks with the hangers flipped). Thoughtful, careful design is evident in every detail of their construction; IMHO the most underrated RKP trucks on the market and unrivaled by any other non-CNC’ed RKP truck out there
