Picture this: your 1/10 scale TRX4 RC crawler powering up a sheer rock face, tires gripping perfectly, no hesitation or slip. That's the reality with the AMK Steel TRX4 CVD Kit. If you've ever watched your rig's stock drive shafts bind up on steep angles or wear out after a few rough sessions, you know the frustration of interrupted fun.
Factory portal axles on the Traxxas TRX4 work okay for casual runs, but push them hard—think deep ruts, loose gravel, or competition-level crawling—and they start to falter. Flex in the shafts leads to inconsistent power delivery, vibrations that shake loose components, and eventual breakage that sidelines your build.
This CVD (Constant Velocity Drive) kit changes everything. Crafted from high-grade steel via CNC machining, the black portal axle drive shaft set withstands brutal torque and extreme angles. It comes complete with eight rubber-sealed metal ball bearings: two 12x18x4mm, two 10x15x2mm, four 6x13x5mm, four 4x10x4mm, and four 6x12x4mm—everything sized perfectly for a drop-in upgrade.
Expect sharper articulation, where suspension flex translates directly to forward progress. No more wheel spin on slick surfaces—these shafts maintain contact and momentum. In practice, users report crawling over obstacles twice as high without drama, and the setup holds up through dozens of trail days.
Installing is straightforward for anyone familiar with TRX4 mods: swap out the old shafts, press in the bearings, and you're rolling. Pair it with portal axles for max ground clearance, and hit the backyard, local rock garden, or scale comp. Whether you're a weekend warrior or comp veteran, this kit keeps the focus on the thrill, not repairs.
Grab the AMK Steel TRX4 CVD Kit and transform how your crawler conquers the wild. It's the reliable upgrade serious off-roaders swear by.
