Picture this: you're out on the trail, your 1/10 scale TRX4 facing sheer rock faces and muddy ruts that would snap lesser parts. That's where the AMK Steel TRX4 Portal Axle CVD Kit shines—delivering bombproof durability so you can focus on the fun, not the fixes.
Factory setups on RC crawlers like the Traxxas TRX4 work fine for casual runs, but crank up the difficulty with portals and heavy articulation, and they start binding, wearing out, or straight-up breaking. You lose torque, gain slop, and spend more time wrenching than wheeling.
This black CVD (Constant Velocity Drive) kit swaps in seamlessly, crafted from high-grade steel via CNC machining for tolerances that eliminate slop. The portal axle drive shaft set includes a matched assortment of rubber-sealed metal ball bearings: two 12x18x4mm for mains, two 10x15x2mm, four 6x13x5mm, four 4x10x4mm, and four 6x12x4mm. Everything's sealed against dirt and water, keeping them spinning freely through puddles and dust clouds.
Total kit weighs just 68g (2.4oz), so no penalty to your rig's agility. The CVD joints handle extreme angles without pinching, transferring every bit of motor grunt to the wheels.
Expect noticeably smoother drivetrain action—less vibration, more consistent crawling speed on inclines. These parts shrug off impacts that trash plastic alternatives, extending your bash sessions. On technical lines with lockers engaged, the constant velocity keeps both axles pulling evenly, reducing tip-overs and getting you over obstacles faster.
Bolt it on during your next maintenance day; no special tools needed beyond basics. Pair with portal axles for lifted ground clearance, or run stock for pure driveline toughness. Whether you're competing, trailering to the mountains, or backyard bashing with buddies, this kit turns frustrating stalls into triumphant summits.
Grab the AMK Steel TRX4 CVD Kit and make your crawler truly unstoppable. It's the upgrade detail-oriented drivers swear by for peak performance.
