RPM Wide Front A-Arms for Traxxas Rustler/Stampede (Black) (2)

This is a pair of optional RPM Wide Front A-Arms. Are you looking to add some serious stability to your electric Rustler or Stampede 2wd? Look no further! RPM wide front A-arms will push your front wheels out there almost 1-1/4” (31.8mm) of total width for some serious stability-adding performance. These 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 “NOTE:” below) and bolt on a set of rear wheels! It couldn’t be easier. Available in black, blue or green.
You already know RPM A-arms are the toughest molded a-arms in the R/C industry (gram for gram, stronger than aluminum as well)! Each RPM A-arm is molded from RPM’s trademark blend of nearly indestructible nylons and backed by their world-renowned limited lifetime warranty against breakage. RPM durability combined with RPM affordability; there’s no way you can go wrong!

Greg Verified Owner Sunday, Oct 18 2020 (about 4 years ago) RPM Wide Front A-Arms for Traxxas Rustler/Stampede (Black) (2) Well made as usual, but front end is now wider than rear, even after installing rear thin hex on front, front is still 1/4″ wider than rear.
Running rear offset wheels front & rear, & rpm rear arms with these wide front arms.
Pro-Line ProTrac arms give proper offset, are much stiffer, improve handling, and better for driveshafts. 0 of 6 customers found this review helpful. View all reviews
