West Coast Drive Bearing Blocks (5 choices)

In recent years, the "West Coast Drive" (WCD) has exploded in popularity among FIRST ® Robotics Competition teams. With their cantilevered wheels and direct-driven axles, teams using this iconic drivetrain style have risen to the top of the competition with remarkable success; however, the precision machining capabilities necessary can cause reluctance among some teams.

VEXpro and West Coast Products (WCP) have teamed up to solve this problem. The VersaBlock easily bolts on to the outside of the pre-drilled VersaChassis tubing - no precision machining needed to achieve a precision aligned drivetrain.

For users who prefer the traditional “milled slot” approach, the 2-piece WCP Side Bearing Block provides a lightweight and compact solution. The 1-piece WCP Gearbox Bearing Block is a similar version, intended to be used directly with WCP WCD-configured gearboxes.

When paired with the WCP Cam to ensure proper tensioning, all teams now have access to a complete, high-performance, "West Coast"-style Drive.

New for the 2018 season, the VersaBlock Mini is a smaller version of the original VersaBlock Kit. The VersaBlock Mini uses ⅞” OD bearings, and clamps around a 1” x 1” VersaChassis tube. You can also use the VersaBlock Mini in tandem with our new 1" x 1" plastic VersaFrame tubing. This means that if you’re an FTC team, you can use these to make your drivetrains even smaller and lighter!
