Build Faster. Stronger. Smarter.
This featured collection highlights the parts our customers use to set PBs and win: 7075-T6 aluminum upgrades for Arrma 1/7 & 6S platforms (Limitless, Infraction, Felony, Typhon, Kraton), carbon-fiber aero kits, electronics, driveline, batteries, wheels/tires, and pit essentials—all curated and tested by Perfect Pass RC.
7075 Aluminum Upgrade Parts (Arrma 1/7 & 6S)
Engineered to survive high-speed abuse and reduce flex: suspension mount sets, steering & camber links, center-brace mounts, and full aluminum A-arms for Limitless/Infraction/Felony/Typhon. Expect tighter tolerances, higher rigidity, and more predictable handling at 100+ mph.
Carbon-Fiber Aero & Chassis Accessories
Lightweight, stiff panels and kits for Arrma Limitless & Infraction (matte, glossy, forged) to stabilize the car at speed and clean up airflow for longer, straighter passes.
Motors, ESCs & Controllers
From high-output motors to elite ESCs (including the Cobra-class units) plus steering gyros—dial in launch control, stability, and repeatability for drag and speed-run builds.
Servos (High-Torque / Metal Gear)
Fast transit, high stall torque, and durable geartrains built for 1/7–1/8 platforms where steering authority matters at triple-digit speeds.
Pinion & Spur Gears, Driveline Hardware
Match gearing to your track and temps with our gear selection and heavy-duty hardware—built to transmit big power reliably.
LiPo Batteries (Speed-Run & Drag)
High-discharge packs selected for low IR and repeatable voltage under load; ideal for long high-speed pulls and clean launches.
Wheels, Tires & Fitment Parts
Speed-focused wheels/tires and supporting hardware for stability, grip, and durability when it counts.
