SDS MK4i Spacer & Shaft Kit V3
This kit contains the shafts and common spacers used in the MK4i swerve module. It also includes the Encoder Guard, but does not include the motor-specific spacers, which can be purchased as part of the motor pinion gear kits.
SDS MK4i Swerve Modules (Non Assembled, L2 6.75:1, No Motor, Kraken Pinion, CANCoder, Colson Wheel)
The MK4i module inverts the motors on an MK4 module to a lower position where they are out of the way and better protected. Overall height and center of gravity are therefore lower. The MK4i module also moves the wheel further into the corner of the chassis for a wider wheelbase which results in a more stable robot. Because the wheel is moved into an area the frame would typically occupy, the MK4i includes a secondary plate to properly box in the chassis.

SDS Gear Ratio Kits L2
These gears are the controlling factor for the SDS modules' drive gear ratios. The MK4 is compatible with all 4 drive gear ratios. The MK4i is available in ratios L1-L3. L1 and L2 ratios are the most popular ratios and are suitable for standard full-weight competition robots. The L3 ratio is more aggressive and is recommended for lightweight robots. The L4 ratio is very aggressive and is only recommended for very lightweight mini bots.
L1 Gear Ratio 8.14:1 (MK4/4i):
- 25T-50T 20DP Double Gear
- 19T 20DP 3/8 Hex Bore Gear
L2 Gear Ratio 6.75:1 (MK4/4i):
- 27T-50T 20DP Double Gear
- 17T 20DP 3/8 Hex Bore Gear
L3 Gear Ratio 6.12:1 (MK4/4i):
- 28T-50T 20DP Double Gear
- 16T 20DP 3/8 Hex Bore Gear
L4 Gear Ratio 5.14:1 (MK4):
- 28T-48T 20DP Double Gear
- 16T 20DP 3/8 Hex Bore Gear
