This Upgrade Makes NO SENSE… But It Works 😳

This Completely Changed My RC Crawler… #rctruck #rctruck #prolineracing link to buy Horizonhobby https://alnk.to/5Q9icCz Order from Amain https://alnk.to/cSLBsbG The Pro-Line Rock-Tek Tire Weight System is one of the most innovative upgrades I’ve seen for RC crawlers — designed to keep weight low and improve traction where it actually matters. Instead of traditional brass weights that rotate with the wheel, the Rock-Tek system uses a magnetic weight setup that stays positioned at the bottom of the tire. That means better balance, improved climbing performance, and more control on technical terrain. In this video, I’m taking a first look at the Rock-Tek system and showing how it works, how it installs, and whether it’s actually worth adding to your crawler setup. 🔥 Key Features: - Magnetically controlled weight system (does NOT spin with tire) - 108g brass weight pairs for low center of gravity - Compatible with most 1.9” crawler wheels (~0.8” width) - Includes bearings, magnets, housings, and hardware for SCX10 III & TRX-4 If you’re serious about improving your RC crawler performance, this might be the upgrade you didn’t know you needed. 👇 Check it out here: https://alnk.to/5Q9icCz --- #RCCrawler #ProLine #RockTek #RC4x4 #RockCrawling #ScaleRC #AxialSCX10 #TRX4 #RCUpgrade #CrawlerLife #RCPerformance #RCMods #TrailTruck #OffRoadRC #RCAddict 0:00 intro 0:30 Pro-Line Rock-Tek Tire
