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

The blade is not sharpen.
Style: Lawn Edger w/(1) 4.0 Ah Battery
I had no problems assembling the equipment. The problem is with the blade. It doesn't have any sharpen. I bough spares blades which have a different configuration and better edge. However I haven't been able to unscrew the bolt in order to install the new blade. It is extremely tied. One would think that you purchase this equipment, at a high price, and would be able to use it right away. In your dream. This is a Third World Country selling things at an incredible high prices, for the profit of the American companies using the manpower of other Third World Countries or China.
Since the blade is not sharp, when you try to use the equipment it got disconnected. Therefore it does not work with the blade that comes from the manufacturer. Total disaster.

Worx very well!
Style: Lawn Edger w/(1) 4.0 Ah Battery
Worx very well. ;)
More power than I expected from a 20v cordless machine. And with the 4Ahr battery it comes with, I was able to do the drive, walks, and patio without having to change batteries. I own 2 Worx string trimmers, chainsaw, hedge trimmer, drill impact driver, and leaf blower. Love them all.

Problematic instructions
Style: Lawn Edger w/(1) 4.0 Ah Battery
The product is great once u figure out how to assemble. The instructions don’t do it. I was not happy. Every part was a challenge. The instruction book only shows a photo but not how to get it to look like the photo.
