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. 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. 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. Top of baseplate sloped for flush contact with deck concave when dropthrough-mounted. (Nut seats kept flat.)
