Swerve Drive Specialties is proud to release our next swerve module iteration, the MK3. It is further refined, simpler, lighter, and less expensive. MK3 is a no compromise top level module at a very competitive price.

I’ll be the first to admit that the MK3 module looks quite similar to the MK2. So, what are the advantages? The most notable design difference is the centrally located steering encoder. The MK3 uses an on axis CANcoder or SRX Mag Encoder to directly measure steering angle without the use of gears. This simplification has numerous advantages. It eliminates encoder backlash, makes module maintenance easier, and perhaps most importantly reduces the part count and cost.
We are passing along cost savings from this design change as well as cost savings from sourcing and process improvements to our customers. The price of the MK3 is $100 less than the MK2. Starting price of the standard kit is $300.
The MK3’s double gear is a key component to the design. It is machined from a single piece of 4140 steel and is pocketed for weight reduction. Even though the MK3 module features an all steel gear train for the best longevity, it is 0.2 pounds lighter than the aluminum geared version of the MK2 module.
The MK3 is available with standard or fast gearing. The table below shows the gear ratios and free speeds with NEO and Falcon 500 motors.
The MK3 is fully configurable from Swerve Drive Specialties. Choose what type of motors you plan to use, what gear ratio you would like, and if the Billet wheel is included. We are also offering individual MK3 parts and a MK2 to MK3 upgrade kit.
