Boost your simulation immersion with the Sigma Integrale DK2+ motion system

The big brother of the DK2 system, the DK2+ motion system offers a more powerful actuator with increased torque for increased fidelity and better quality ride. The DK2+ is a professional motion system for serious sim racing and flight sim enthusiasts. It’s also perfect for commercial applications. If you want to take the immersion and realism of your sim rig to the next level, there’s no better way than with a motion system like the DK2+ from Sigma Integrale.

The DK2+ motion system is designed, engineered and constructed in-house at the Sigma Integrale facility in Pomona, California. This stunning simulator actuator kit is constructed from machined billet aluminium and is ‘8020’ friendly, meaning it will bolt directly onto most aluminium profile cockpits including Trak Racer TR80, TR80 Lite, TR120, TR160, SimRigs Exodus, 6 Sigma Racing and the Next Level Racing GT Elite (not the F-GT Elite due to the lipped chassis profile).

With the Sigma Integrale DK2+ bolted to your rig, you'll have a powerful 3DOF motion simulator at your disposal. You'll be able to feel realistic pitch, roll and heave. Immersion levels go sky-high as you can feel bends, acceleration, braking, hits, knocks and more.

The system is plug and play with compatible simulation titles. You simply bolt the DK2+ actuators to your cockpit, plug in the motion controller box, calibrate the custom Sigma Integrale software to your liking and you’re ready to play!

State-of-the-art motion system

Sigma Integrale have created one of the best value, highest quality and best performing 3DOF actuator systems on the market today.

Everything about the DK2+ system reflects Sigma Integrale’s commitment to quality and performance. From the high-end, billet aluminium actuators built in-house to the motion control system that’s sleek, stylish and easy to use to the custom motion software that you can calibrate to your specific liking. If you’re looking for a motion system to bolt onto your racing or flight cockpit, the DK2+ should be high on your shopping list.

With the Sigma Integrale DK2+ motion system installed you'll instantly feel realistic in-game feedback including acceleration, braking, gear changes, bends, hits, knocks and more.

Designed, manufactured and tested in California

The entire DK2+ motion actuator system is made in-house at the Sigma Integrale facility in Pomona, California.

Each actuator features a mono-block structure and is crafted from machined billet aluminium. The floating feet on each actuator are also made from billet aluminium. This is a heavy-duty motion system that’s made for thousands of hours of gameplay. In fact, the test system set-up at Sigma Integrale’s facility has completed more than 8 years of comparable gameplay.

The DK2+ motion system is mechanically and electrically engineered around Sigma Integrale’s unique motion algorithm to provide the most realistic and representative vehicle motion feedback. This makes the DK2+ one of the most responsive motion systems on the market. Every elevation change, vehicle movement, surface change and gear shift, is captured and reproduced within 50mm of the available mechanical stroke.

Unlike other motion systems on the market, the motion controller system included with the DK2+ is sleek and around the same size as an old-school DVD player. No big, bulky cabinets. No gigantic servo controllers. All the essential operation electrics are stored within this neat, white box.

Complete plug and play system

The Sigma Integrale DK2+ is a complete plug and play motion actuator system. Simply attach the actuators to your rig, plug the power and network cables into the motion controller, calibrate the software and you’re ready to go.

With the motion controller, you’ll get lifetime access to all future ‘over-the-air’ updates and feature add-ons.

Sigma Integrale have made it easy for serious sim enthusiasts to finally enjoy a high-end actuator-based motion system without the need to invest hours and hours in set-up time. If you’re not overly great with technology and worried about the technical side of setting up the DK2+ system - don’t. With the included instructions the set-up is super simple and easy for anyone to do.

Includes everything you need to get started

The DK2+ motion system includes everything you need to get started right out of the box:

  • 4x actuators
  • Motion controller system
  • Power and network cables
  • Installation accessories

NOTE: You’ll need an available network port on your PC or a USB to Network adapter

The DK2+ system will bolt directly onto most ‘8020’ style aluminium cockpits with t-slot extrusion including Trak Racer TR80, TR120 and TR160, SimLabs, SimRigs Exodus and 6 Sigma (6S-80, 6S-120 and 6S-160 models).

Please note that Sigma Integrale motion systems are made to order and require approximately 2-3 weeks for build, testing and shipping.

Hey there.

If you’ve clicked on this tab, you’re obviously looking for a reason or two on why you should shop for your gaming goodies at Gamer Gear Direct, rather than those other online stores.

And we’ll (not so) humbly say there’s lots of reasons we think you should shop with us…and not hand over your hard-earned cash at one of those big box retailers like Harvey Norman or JB Hi-Fi. 

First up, we’ve got a policy here at Gamer Gear Direct we like to call…

100% customer happiness guaranteed (we mean it!)

OK, so the above title might sound a little corny to you, but it’s true. 

We’ll bend over backwards to ensure you are 100% happy and satisfied with everything you buy from us. 

We want you to tell your friends and family about your experience with us (and hopefully that’ll mean they visit our website, too). 

And the only way you’re going to do that is when you’re happy with our service, right?

See, we’re not one of those big box electronics stores with a multi-million marketing budget. Those companies treat you like a number. Because they can afford to! They’ve got money coming out of their ears.

We’re different. We’re a small Aussie business. Every single potential customer that hits our website is precious to us (that includes you). 

So, again, we’ll do everything we can to make sure you’re over the moon with your Gamer Gear Direct shopping experience.

Do you think Harvey Norman can promise that kind of service? Probably not.

But look, you don’t have to take our word for Here’s what our customers are saying about us…

Ashley Woolnough says: ‘I want to say a huge thank you to Blake and the team at Gamer Gear Direct. The service has been absolutely impeccable from the moment I first looked at items to the moment they were delivered. I bothered Blake quite a bit, but nothing was too much trouble and he went above and beyond to help me. 5-star service’.

Joe Platt had this to say: ‘Just want to say how awesome the gaming chair is that we bought. Amazing quality, helpful service and the fastest delivery of an online purchase. Arrived Next Day!’

And this from B. Richardson: ‘Purchased an Audeze headset and it arrived inside two days. Thanks for the fast shipping and great service!’

That’s not an exhaustive list, either. There are plenty more happy customer stories we could share with you.

But let’s move on…

Five-star customer support. We’re just an email, phone call or live chat away. We’re here to help you day or night

‘Officially’ we’re around to support you and help you out with your questions and queries between normal business hours (Mon to Fri, 9am to 5pm).

But just between us…we’re pretty much here to help you out around the clock, 7 days a week.

We don’t switch off. For example, it’s not unusual for one of our team to be helping a customer with a shipping request at 9pm at night. 

If you need a hand with anything just email us, call (03) 9000 0545 or open the live chat function and we’ll help you in any way we can.
