RPM A-arms for 4S BLX versions of the ARRMA Kraton & Outcast are designed primary for strength and durability but we’ve added a few extra features in as well.First is slop elimination. Our A-arms reduce the amount of movement of the A-arm at the hinge pins, providing for better steering response and more consistent camber, caster and toe angle settings.
Our next improvement is the addition of a second shock mount hole further out on the arm, providing for a lower profile suspension set-up. This shock position allows the suspension to lay down a little further, dropping the ride height for a lower center of gravity and better cornering stability.
Our most important update is durability. Our new A-arms are massive! At almost 25% thicker than stock, our A-arms will take a pounding and come back for more! All RPM A-arms are molded from our nearly indestructible blend of engineering grade nylons for performance you can rely on when conditions are at their worst!
Tech Notes: RPM A-arms for 4S versions of the ARRMA Kraton & Outcast are sold in pairs. Front A-arms replace stock #AR330520.

Orange Ball Endless Dog Zoomies
Color: Tangerine - 3.15Inch
My dog was immediately curious about this ball, and it quickly turned into one of the toys that gets pulled out multiple times throughout the day. The movement keeps things interesting and encourages chasing in a way that a regular ball doesn’t. I like that it keeps my dog occupied when the weather isn’t great for long outdoor play sessions. The textured surface provides a decent grip when carrying it around the house. It has bounced off furniture and walls a few times and still looks surprisingly good afterward. The size worked well for my medium-sized dog and was easy for him to grab. There were a couple moments where it got stuck in tight spaces, but that’s more a result of enthusiastic play than a problem with the toy itself. The activity level definitely increased when this ball started moving around. It’s been a fun way to add a little extra excitement to indoor playtime.

Easy to charge and bounces nicely on the grass
Color: Tangerine - 3.15Inch
Getting the kids' backpacks ready usually means the dog gets ignored for a bit and starts pacing. I turn this ball on and toss it out the back door. It has a surprising amount of bounce on the grass, and the random movements keep him running circles trying to catch it. Pushing the button to switch the rolling modes is straightforward. The battery gets me through a few play sessions before it needs to be plugged back in. The outer shell gets pretty dirty outside, but wiping it down with a damp rag cleans it right up. It’s got a decent weight to it, so it doesn't just get stuck under the lawn chairs immediately.

Beware of poor quality issues!
Color: Orange - 3.15Inch, Color: Orange - 3.15Inch
Got limited use out of ball, seemed to have quite a strong motor and was going to be a good buy. But upon going to recharge it for the first time, discovered the USB port was completely loose/not attached. Will steer clear of this brand going forward.

The Ball Never Gets Boring
Color: Tangerine - 3.15Inch
My dog was immediately curious about this ball, and that curiosity turned into a surprisingly long play session. The movement keeps things unpredictable enough that it holds attention longer than a standard toy. I liked that it encouraged activity without requiring me to constantly throw something across the room. The textured surface also seemed easy for my dog to grab and carry around. One thing I noticed is that hard floors allow the ball to move around much more dramatically than carpet. It feels sturdy enough to handle enthusiastic play and occasional chewing. The bright color makes it easy to spot when it inevitably ends up under furniture. Charging was simple and didn’t become a hassle.

Tough build for rowdy play sessions
Color: Tangerine - 3.15Inch
I picked up this motorized E-TPU dog ball last Thursday to keep my German Shepherd occupied during my afternoon video conferences in Folsom. The product quality is evident in the spongy, high-density foam construction, which provides a satisfying grip for his jaws without sustaining a single tear or puncture. The built-in motion sensor is highly responsive, sending the ball into an unpredictable frenzy of hops and spins whenever it gets nudged. It offers excellent value for money because the structural integrity holds up perfectly against aggressive chewing that would normally shred standard rubber toys in minutes. For a parent or professional needing a functional, autonomous distraction to burn off their pet's excess energy indoors, this rugged smart toy delivers a very reliable and quiet performance.
