Tesla Model 3 Rear Drive Unit Reduction Gear Set 3.54:1

Upgrade the gear ratio of your Tesla Model 3 rear drive unit with this precision-engineered 3.54:1 reduction gearset.

This lower ratio enables significantly higher output speeds, making it ideal for:

• High-top-speed EV builds
• Central-mounted drive units in 4x4 conversions with prop shafts on both sides

This gearset is commonly used in custom conversions of:

• Land Rovers
• Ford Broncos
• Toyota Land Cruisers

⚠️ Important Notes:

• Increased Gear Noise:
  Due to the higher output speeds and mechanical nature of the reduction, some gear noise—especially while coasting or under inconsistent load—is expected. This is typical in performance applications and drivetrain setups not under constant load.
• Installation Tip:
  For easier assembly, freeze the gear shaft prior to pressing it into place. This will contract the metal slightly and ease the interference fit.

Ideal for changing the gear ratio of the amazing and affordable Tesla Model 3 Rear Drive Units.  Note: compatible with front drive units with some modification of the internals.  Contact us to discuss.
