OffRoadOnly has taken the SwayLOC Dual Rate anti-swaybar system proven in the Jeep Wrangler application and developed an application for the Polaris RZR XP1000/XPT1000.

The SwayLOC anti-swaybar system is unique in that there are 2 individual torsion bars to deliver 2 different rates of control, and for the RZR applications OffRoadOnly has incorporated an electric actuator to allow for easy, shift on the fly adjustment from the driver seat.

Simply flip the switch to transition between the firm setting for high speed control and the soft setting delivering full articulation for extreme crawling action. The smart latching system will only engage in the firm mode when the chassis is in the level position.

With the latch engaged the firm rate is comparable to if not just a touch firmer than the OEM RZR rear sway bar. So flip it to the engaged mode and stand on the gas pedal! Experience full confidence that your RZR will behave as it did with the stock bar. The components shown in these photos are early design, the production units will have 3 separate morning points for the linkage attachment, allowing for some adjustment in the firm rate.

With the latch dis-engaged the softer rate will allow near full range of articulation, similar to what can be experienced by simply removing the stock bar. Our testing has concluded that most vehicles experience as much articulation with the SwayLOC in the softer rate as they do without a sway bar, however, there is a noticeable balanced feel with the SwayLOC that is missing when running without a sway bar.

The following link is to a YouTube video of our test rig in both modes thru a rough section.


Realizing that the OEM sway bar brackets are at times the weak point in the system, OffRoadOnly went one step further and developed the mounting bracket system to not only utilize the factory mounts, but also extends the brackets above and below the factory bracket and clamps to the RZR tubing framework, providing a wide range of load support to re-enforce the mounting brackets.

SwayLOC is a 100% bolt on kit and typically can be installed in approximately 90 minutes. And since it is bolt on, it is also easily removed to be able to be transferred to another machine should the need arise.

Polyurethane bushings are utilized between the mounting brackets and the SwayLOC torsion bars, these allow a slight amount of give and provide noiseless mounting. The SwayLOC torsion bars incorporate a grease fitting on the end of the inner bar, allowing for regular service to lube the wearing area inside the bars. The rod ends on the linkages are 3 piece quality rod ends, which also incorporate a grease fitting to allow regular maintanence.

These RZR kits utilize a short travel 12 volt electric actuator. These draw at max appx 3 amps, but we have not seen near that much draw during our testing. From the actuator is a 2 connductor cable that plugs into a sealed Carling rocker switch. Simply attach the positive side to a 12 volt supply. As the actuator reaches the end of its travel, a limit switch opens the circuit preventing current draw until the switch is flipped, so the circuit is simply flip it and forget it until you flip it again.

These SwayLOC kits are comprised of steel and aluminum components and these parts are zinc coated, epoxy (e-coated) or anodized as needed for a quality finish that last a long time.

Some words from our customers;

Everything from the packaging and instructions plus the miscellaneous items needed for a clean install were all there which is something I am not used to.
The product has been well machined and fit like a freaking glove with no modifications required (which is not industry standard based on my experience).
My immediate impression was how much more stable and responsive the machine felt with the bar locked!
Next test came on the rocks and I thru everything at it!!!!! And I cannot give it enough stars!
It’s very seldom I feel like I got more than what I had paid for and this falls in that category!!
I would and will highly recommend this product to take your RZR to the next level.

Just got done with a week of riding in moab. The swayloc worked flawlessly a much bigger improvement than I anticipated. The ride was so smooth and nice to be able to lock and unlock when needed.

I think it’s money well spent!
