Rzcazzide 21807G1 EZGO Golf Cart Brake Drum – 30-Tooth Spline, 1-Inch Hole, OEM 21807-G1

Overview

Upgrade your EZGO braking system with the Rzcazzide 21807G1 brake drum, designed for a precise 30-tooth spline interface and a large 1-inch center hole. This part is built to align with EZGO TXT and a wide range of models, offering a robust, reliable fit that supports consistent stopping power on 4-cycle gas carts and select electric configurations. By focusing on a durable steel composition and exact fitment, this brake drum aims to minimize play and maintain smooth operation under regular use.

Designed to replace several OEM identifiers (including 21807-G1 and 41843-94), this component helps ensure compatibility across multiple EZGO generations. Notably, it is not intended for ST350 or 2-cycle gas models that require a smaller 0.75 inch hole. The result is a practical, hands-on upgrade that can help you maintain the feel of your cart’s braking system without unnecessary guesswork.

Key Benefits and Fitment

• 30-tooth spline with a 1-inch center hole for a secure, accurate fit on compatible EZGO rear hubs.
• Broad compatibility across EZGO TXT, RXV, Medalist, Marathon, Shuttle, Workhorse, and Columbia-era carts (gas and certain electric models).
• Durable steel construction with resistance to wear and friction, designed for repeated stop-and-go use.
• Comes as a complete package with essential hardware to simplify replacement and reassembly.

What’s Included and Installation Notes

• 1x EZGO brake drum with lug bolt, plus 2x washers, 4x lug nuts, and 1x cotter pins.
• Important caution: check rear axle splines for looseness or wear before installation to avoid hub damage.
• Regular inspection is recommended to maintain safe operation and consistent braking response.

Usage Scenarios

Whether you’re tuning a classic Medalist, refreshing a TXT, or servicing a modern RXV, this brake drum supports steady deceleration and a solid feel when you apply the brakes. The combination of precise spline engagement and a robust center hole helps reduce play, supporting predictable performance during daily driving or longer rides.

Note: This part is intended for 4-cycle gas EZGO carts and selected electric configurations. Always verify model compatibility against your cart’s specifications and the OEM references listed in the product notes.
