Reflex Racing Aluminum Gear Differential - RX538It's finally here! Our all new Gear differential was designed to be a high quality and high performance addition to your 1 28 scale car. More rotation and harder acceleration than the ball differential yields a car that is often about a tenth faster to drive in high traction surfaces. The feel of this gear diff is very balanced and this makes the acceleration super smooth and strong. At only about 4. 7g, it is also super light for less rotational
It's finally here! Our all new Gear differential was designed to be a high quality and high performance addition to your 1/28 scale car. More rotation and harder acceleration than the ball differential yields a car that is often about a tenth faster to drive in high traction surfaces. The feel of this gear diff is very balanced and this makes the acceleration super smooth and strong. At only about 4.7g, it is also super light for less rotational mass.
The gear diff is sealed from the elements as the gears are inside a machined aluminum case in which you can larger amounts of grease to change the behavior of the differential action. The ticker the grease, the lower response into the corner, but this could be at the expense of a little bit of exit traction. We don't recommend going too heavy on the oil (maybe use no more than 1 or 2k CST oil), but you can use oil with no leakage at the spur and only slight leaking at the outputs.
**Please not the diff is not sealed at the bearings, so it is not designed to be "filled" with oil , but a healthy amount can be used when building. Left hub is not included.

Sam Edelman never disappoints! I love the chucky heel and the multi-colors and textures. Can't wait to rock these with a leather skirt and turtleneck!

I'm very pleased with the purchase of this bag
Color: Pink
The bag is made of a very subtle pink, supple leather. It seems to be of good quality and I hope that over time, with wear, this turns out to be true. It's a good size -- not too small, not huge, but just enough to fit plenty of necessities for a day or evening out. The style is sleek and uncomplicated, making it versatile enough to be worn on casual days as well as a night out. The top is secured with a smooth-running zipper that keeps everything safe yet easily accessible. The shoulder strap is adjustable to various lengths including one that is very long which is my preference. The handles are wrapped in matching leather and very comfortable. The only improvements I'd make to the bag is the addition of brass feet on the bottom and I'd make the zipper pocket on the outside back of the bag slightly wider so my phone would fit into it. Overall, I like it very much and have already recommended it to family and friends.
