Picture this: you're deep in a rock-crawling session, your Traxxas TRX-4M scaling sheer boulders, and everything spins smooth as butter—no grinding, no hesitation. That's the reality with this INJORA 22-piece steel sealed bearing kit. If you've ever pulled apart your crawler after a muddy bash only to find stock bearings packed with grit and starting to seize, you know the frustration.
Standard bearings on the TRX-4M are fine for casual driveway runs, but they don't hold up under serious abuse. Dirt, water, and debris sneak in, causing drag that saps power and wears components prematurely. Before long, your axles bind up, diffs whine, and climbs turn into slips. It's a common headache for RC enthusiasts pushing their 1/18 crawlers to the limit.
These INJORA bearings change everything. Crafted from high-grade steel with rubber seals on both sides, they lock out the elements while letting high-RPM rotation flow freely. The kit includes 22 precisely sized pieces covering all critical points: wheels, diffs, transmission, and more—everything your TRX-4M needs for a full refresh. They're a direct drop-in upgrade, no modifications required.
I've swapped these into my own TRX-4M, and the difference hits immediately. Wheel spin is buttery, diffs engage crisply, and the whole drivetrain feels alive. On technical trails, it powers over obstacles that used to stop me cold. Maintenance drops too—no more constant cleaning or early replacements. Whether you're bashing with buddies at the park or dialing in for comp crawling, these bearings handle the punishment.
Pop the old ones out with basic tools in under an hour, press these in, and you're back on the trail. Pair with metal gears or portal axles for even more ruggedness. RC crawler upgrades don't get more straightforward—or effective—than this. Grab the kit and keep your TRX-4M crawling strong, session after session.
