RC enthusiasts, listen up! If you're running a Traxxas E-Rustler or Stampede 2WD and want some serious stability improvements, these RPM wide front A-arms are exactly what you need. They push your front wheels out by almost 1-1/4 inches (that's 31.8mm for you metric folks) of total width, which makes a HUGE difference in how stable your ride feels, especially when you're tearing around corners or at high speeds. The cool part is they extend the front width to match the difference between your front and rear wheel offsets, so everything balances out perfectly. They come in this sleek black color and include both right and left arms - everything you need for the upgrade. Installation is pretty straightforward if you're familiar with basic RC maintenance. Just imagine how much better your Rustler or Stampede will handle with that wider stance - less tipping, better cornering, and overall more control. The package is compact too - about 4.13 inches long by 6.25 inches high - but the impact on your driving experience is massive. Whether you're bashing around the backyard or setting up for some serious racing, these A-arms will take your Traxxas game to the next level without breaking the bank. Definitely one of those upgrades you notice immediately after installing!
