PRODUCT INFORMATION:

  • Introducing the strongest AR44/AR45 axle gears to date: Keyed Underdrive 33/8T HD Helical Bevel Gears + Differential Locker Set for AR44/AR45 housings #BR955042.

    The SCX10 II stock axle gears are known to be a weak point in the housing. After releasing the popular Keyed 27/8T Overdrive Hardened Steel Gears, requests were sent in for underdrive gears. So YOU asked, and we listened!

    Here is the new heavy-duty underdrive 33/8T helical bevel gear & diff locker set.
    Designed for the AR44/AR45/Capra Currie F9 Axle Housing, Boom Racing AR44 PHAT Axle Housing or the BRX70/BRX80/BRX90 PHAT Axles.

    Use this gear to improve the performance of your crawler. Run them in the rear axle for a slower wheel speed in the rear tires. Underdrive gears help to steer in sharp turns like how a dig does and slower wheel speed in the back with higher torque output.

    Features:
    Underdrive gears create slower wheel speed for rear wheels to help steering with higher torque output
    Hardened steel gears for maximum strength and durability
    Keyed spool to increase structural strength and to eliminate the weakness of the M2 screws
    Tight tolerance of the diff locker and the axle shaft
    Tight tolerance of the bevel gear and input shaft to increase efficiency in the drivetrain

    Fits:
    Boom Racing BRX70 PHAT Axle
    Boom Racing BRX80 PHAT Axle
    Boom Racing BRX90 PHAT Axle
    Boom Racing PHAT AR44 Axle (BR955015)

      Elegant, Lightweight & Eye-Catching
      Color: Green, Size: 3 clover, Color: Green, Size: 3 clover
      These are really nice earrings—long and elegant without feeling heavy at all. They’re super lightweight, so they’re comfortable to wear all day. The design is eye-catching and adds a nice statement without being too much. The green detail is pretty and gives them a unique look. They hang nicely and move just enough to catch the light. Great quality, stylish, and easy to wear.

      Probably not real malachite
      Color: Green, Size: 2 clover, Color: Green, Size: 2 clover
      These have a malachite-look insert in the bottom dangle piece. I'm pretty sure it's not real malachite though - probably a plastic piece or such. I only marked it down one star though because it still looks very nice (and it doesn't claim to be real anywhere). From more than an couple inches away it looks fine though. I say this because the green part in mine is identical between the two, has a plasticy sheen to it (no variation like real stone), and the back is white (not green). It's a sparkly set of earrings though and the green is a nice touch, so I can definitely recommend for casual wear. Just know it's probably not real - but that can be your secret.

      Lovely bracelet
      Color: Green, Color: Green
      This bracelet exceeded my expectations! The pictures truly don’t do it justice—the quality and overall look are even more stunning in person. The cubic zirconia stones are incredibly sparkly and catch the light beautifully. It’s well-made and feels like a high-quality piece of jewelry. I love that it’s not bulky at all, and the two-strand design adds such a cute, elegant touch. It would make a perfect gift for someone special (or yourself!). You definitely won’t be disappointed!

      Nicely made, lightweight and very pretty
      When I ordered this bracelet I didn't realize that it was a double strand design. It is lightweight and comfortable on my wrist and the two strands of different designs add visual interest to the jewelry. It is helpful that the bracelet has adjustable length so that it can be used on small or larger wrists. My picture shows the length as 9", so there is plenty of room to expand or decrease according to how you like it to fit. Another of my pictures shows that the back side of the clover is solid and smooth-- nothing scratchy against your wrist. I feel this bracelet is a good value for the money and would make nice gift.
