DK2 Motion System
Double the performance at half the cost of other turnkey racing motion systems. Utilizing modern controllers with low total loop latency with no distracting effects or gimmicks.
The DK2 motion system is optimized to make quality hardware and haptics available to all drivers in the sim-racing community. Like our other systems, the DK2 is mechanically and electrically engineered around our unique motion algorithms to provide the most realistic and pure representation of vehicle dynamics without relying on pre-recorded canned effects.
The DK2 motion system comes in 4 or 3 actuator versions and is compatible with most aluminum extrusion chassis systems.
All systems ship in satin black anodized finish.
The motion kit includes:
- Billet actuators and mounting brackets
- Our Synapse motion controller
- All required cables and fasteners
All systems take 1 week to build and ship.

Boosted Media
"Pure telemetry data to the seat of your pants!"
Perfect for immersive experiences in off-road racing, rally, and F1.
DK2 takes a modern approach to signal processing and motion control to create the most responsive system on the market. Every elevation change, vehicle movement, surface change and gear shift, is captured and reproduced within 2” (50mm) of the available mechanical stroke.
Value Driven
Made in USA, billet machined and shipping directly to customers around the world.
American Made & Supported
Our premium USA made motors are double the price but triple the performance of other systems. Each actuator is black anodized and features a one-piece actuator design. The pistons are oversized and specifically designed for extreme sideloading.
The best part is no part
Sigma actuators have 50% less parts and components than other manufacturers. This method of lean manufacturing lowers our parts and component lists and drastically lowers our overhead costs.
The best service is no service
Our single piece actuator design uses 50% less parts and components than the competition. This unique feature of our proprietary design makes for easy and fast assembly with exceptional performance and durability.
Direct to Customer
Our DK systems are sold directly to customers from our manufacturing facility in California for the best value and direct support to the end customer from us the manufacturer.
Value Driven
Sigma is value focused, which is to say we are customer focused company. All systems are build to order and we offer the same price all year round. Our product integrators are not resellers or distributors and make a humble margin integrating our systems.
Compare The Competition
Why DK Motion Systems?
Our competitors use generalized canned effects, whereas our focus is on pure telemetry-based motion tailored to motorsports. We offer a robust, billet-crafted system with unmatched haptic quality at a more accessible price, without exhuberent reseller markup.
01 | Mechanics
DK systems are made from billet using precision CNC equipment. This prevents piston deflection, providing long service life with minimal maintenance required. This design enhances vibration transfer to the chassis. Featuring the industry’s largest ball screws and a 2" electroplated piston, our systems ensure smooth, quiet, and durable performance, even under side-loading.
02 | Software & Algorithms
Our proprietary algorithms deliver only game-provided motion, without artificial effects, avoiding false positives and maintaining a sense of realism. The remote UI app enables real-time tuning from your phone. Our Dynamic Scaling algorithm optimizes actuator travel, enhancing experiences in flight and off-road games.
03 | Electronics
We are the only company using a 75-volt DC system, enabling small yet powerful motors and improved cable management with thinner cables. Our system uniquely allows disconnecting and reconnecting power/data cables for easier installation and routing. A 32-bit real-time ARM core processor handles velocity, acceleration, and jerk calculations, setting us apart in the industry.

Which motion system is right for you?
The DK2 motion system delivers exceptional at-home haptic performance with the same mechanical and electrical capabilities in a smaller, more cost-effective design.
DK2+ and DK6+ motion systems feature larger motors with enhanced torque profiles which translates to more precise bump and curb feedback, quicker directional changes, and a smoother, more natural feel.
The DK6+ features 6" (150mm) of travel, as compared to 2" (50mm) with the DK2 and DK2+.
