I was snapping stock a arms every time I drove my slash ultimate, since I got these, I haven't broken them since, it's great peace of mind!
Found to be more durable than stock by far, yet to break any.
The RPM A-Arms were a good replacement for my stock A-Arms.
good replacement after braking my originals
Just go ahead and get a couple pair for your slash 4x4, im still on my first set after months of bashing. They are well worth it!
Hard to break rpm
