  1. ThunderHex

    Starting at: $9.99

    View Details

    ThunderHex Stock & Bearings will revolutionize the ways teams use hex shaft.

    ThunderHex Stock works in all applications where 3/8" or 1/2" Hex Shaft will work and also includes rounded corners. These rounded corners allow the shaft to pilot inside a 10.25 or 13.75 mm round (ThunderHex) Bearing instead of a standard 1/2" Hex Bearing. This eliminates some difficult manufacturing tolerances and results in a MUCH smoother end result. Simply put, ThunderHex Bearings are the best way to create smooth-running hex shafts, and ThunderHex Stock helps you accomplish this without a lathe.

    Also, since you're essentially putting a round peg in a round hole, no more struggling to align the hex of your shaft with the hex hole of your bearing.

  2. VersaHex Adapters (3/8" Hex, 1/4" Long) (217-5948)

    Starting at: $4.99

    View Details

    VersaHex Adapters allows you to change any 1/2" Hex Bore product to either a 3/8" hex, 1/4" square or 6mm D Shaft bore. This means that you can run a GT2 pulley on a 3/8" Hex Shaft, a VEXpro Hub Sprocket on a VEX EDR High Strength Shaft or a VEXpro 20 DP gear on a 6mm D Shaft. Each type of VersaHex Adapters come in 1/8" and 1/4" lengths.
  3. Ball Shifter MagEncoder Mount Kit (217-5906)


    The Mag Encoder is a sensor that measures the rotational position and velocity of the shaft driving your mechanism. After releasing the Mag Encoder a few years ago, we received a ton of positive feedback from the FRC community. However, you also told us that there was not an easy way to actually mount the mag encoder to a ball shifter. That is now a thing of the past with the Ball Shifter Mag Encoder Mount.

    This mount allows users to easily mount a Mag Encoder to any existing VEXpro Ball Shifter. No need to modify any of the Ball Shifters that you already own! Now you can easily add a Mag Encoder to your ball shifter, and it only takes a few minutes to install.

    VEXpro offers several different lightweight shaft stock options made from both 6061 aluminum (for tube axles) and 7075 T6 Aluminum (for high-strength hex shafts handling torsional loads). These shaft lengths are correctly toleranced such that they fit perfectly through bearings and hubs, without extra work.

    While it's tough to get excited about a few pieces of shaft stock, these shafts are specifically created to reduce user frustration. Do yourself a favor, buy some of the good stuff.
