RPM Wide Front Arms for Traxxas Rustler & Stampede

RPM Wide Front Arms for Traxxas Rustler & Stampede

As you Traxxas Rustler 2WD and Stampede 2WD owners already know, the popular RTRs have different front and rear wheel offsets. The rear arms reach deep into the wheels, but the front arms are shorter and use wheels with greater offset to make up the difference. RPM’s new arms match the width of the rears, so you can use “rear wheels” on all four corners of the truck. In addition to making wheel mounting more convenient, extending the life of your tires (since they can be rotated front to back) and opening up a wider variety of aftermarket wheel options, the new arms offer more supple suspension action and enhanced stability. And they’re RPM, so they’re just about break-proof. Not bad for $11.

From RPM:

Are you looking to add some serious stability to your Rustler or Stampede? Look no further! RPM has a new set of wide front A-arms that will push your front wheels out there almost 1-1/4” of total width for some serious stability-adding performance. Our Wide Front A-arms extend the front width by exactly the difference in offset between the front and rear wheels. All you need to do is get a second set of “front” wheels and bolt them to the rear to align the front and rear tires and you’re good to go! No expensive prefabricated widening kits or time-consuming conversions. It’s as easy as replacing your stock A-arms with RPM wide A-arms, swap the turnbuckles and camber links for longer versions (not included see “Tech Notes” below) and bolt on a new set of rear wheels! It couldn’t be easier.

You already know RPM A-arms are THE toughest molded a-arms in the R/C industry (stronger than aluminum as well – gram for gram)! Each RPM A-arm is molded from our trademark blend of nearly indestructible nylons and backed by our world-renowned limited lifetime warranty against breakage. RPM durability combined with RPM affordability and there’s no way you can go wrong!

  1. The parts list has been updated on RPM’s website for this. Don’t order the Toe/Camber Links listed here as they are incorrect for the Stampede at least.
