The AMP Ultra-B Rear Suspension Linkage is a suspension assembly consisting of two separate components: the rear triangle and the suspension linkage, which can be purchased individually or together. The triangle is CNC-machined from 7075 aluminium and is designed with a wider structural platform to better distribute load across the pivot and mounting areas. The linkage is CNC-machined from 6061-T6 aluminium and runs on sealed needle bearings to ensure smooth, consistent movement and long-term reliability in off-road conditions. The linkage geometry slightly revises the rear suspension leverage curve by reducing excessive initial leverage, smoothing mid-stroke behaviour, and adding a small amount of progression deeper in the travel, resulting in improved compression support, reduced rebound instability, and more predictable suspension response. A subtle rearward axle path increase improves traction and stability under acceleration The Ultra-B Linkage System is available in raw silver and additional colour options.
