J- Fischer Verified Owner Tuesday, Apr 1 2025 (6 months ago) Treal Hobby Losi Promoto Adjustable CNC Aluminum Swingarm (Gold) Best option part hands down! Sure its spendy but the ability to “DIAL YOUR EXACT PERFECT TENSION NEEDED INSTANTLY” without inaccurate plastic spacers is priceless and makes a properly tensioned & DRY lubed chain last many times longer than I ever imagined. The stock chain assembly comes way too tight! Adding the next spacer shim was inaccurate too… Chains require proper tension for it (and the sprockets) to last. I’d give this 10 stars for engineering, and 10 more for its perfectly machined parts that fit like a machinist would make for himself. Superior quality above and beyond the usual by a mile.
