This is an optional set of RPM 4S Kraton and Outcast Rear Suspension Arms, intended for use with ARRMA Kraton and Outcast kits and designed for strength and durability with features to better enhance performance. These A-arms deliver excellent slop elimination by reducing 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. The addition of a second shock mount hole further out on the arm provides 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. All RPM A-arms are molded from their nearly indestructible blend of engineering grade nylons for performance you can rely on when conditions are at their worst. These arms are almost 25% thicker and able to take much more damage than stock.
Features:
- Nearly 25% thicker than stock a-arms for extreme durability
- Less slop for improved suspension and steering performance
- Second shock mount hole for added adjustability
- Replaces stock #AR330521

Guaranteed fun for my little dog
Color: light blue
I bought this interactive ball for my dog and I really like it. It's durable and has a design that makes it more entertaining than a regular ball My pet loves to chew on it and play with it for a long time without getting bored. It also feels high quality and safe. Perfect for keeping them active and entertained. I recommend it.

Fun, Durable Toy That Keeps Dogs Entertained
Color: light blue
This interactive dog toy has been great for keeping my dog fairly active and engaged. The auto-bounce and rotating features grab attention instantly, and the chew-resistant material holds up well. You can also turn the multicolored lights on to play in the dark or just have a fun time while your pet chases the ball. It is so easy to use, rechargeable, and perfect for burning energy indoors or outside. 🐶
Although both my dogs were sorta interested…due to colder temperatures (they are elder dogs) they probably would have had more fun, if the weather was warmer. I also tried to entertain the neighbors poodle too!

Fun ball for dog
Color: light blue
This is a great toy for the dog. So far the ball is still complete by chewing several days. I have to say it is perfect size for the big dog. The ball is light and also has a changeable light and models.
