The promoters of Rally on the Rocks and the title sponsor Discount Tire, did an incredible job this year. More vendors, more Sheriffs, more trails and of course more Side by Side machines than any year in the past.

We started the week, catching up with our friends from Highlifter Products. We checked out Nathan’s RZR. Nathan is an off-road addict for mud, mountain, forest trails and of course MB Quart.

Billy from saw us and grabbed some great pics of Nathans bike, showing off his NT1-120LB cans. Billy’s shots will certainly end up on their site too.

Always great to see all the applications MB Quart is used in by real powersports enthusiasts.

Our MB Quart space in the outdoor vendor area was packed with riders looking to upgrade their audio.

We also announced pricing and release dates on the new products for Polaris Audio by MB

Quart that was unveiled in Texas at Mud Nationals. Here’s the video with a quick walk through by Jay Whatley.

First up is the new RZR Radio (part # 2881988) confirmed to be shipping to Polaris Dealers by the end of June with a target price of $399.99. This includes the mounting console and the appropriate cabling for a quick installation. But wait, you will need speakers.

One of the Polaris dealers visiting the MB Quart booth from the midwest was very excited to see the new products on the verge of getting into his store. “This new Polaris / MBQuart radio has more features like Apple Control and clearer sound than everything prior to it”

The great thing about #ROTR is that it is a Rally. Everyone chooses their trails for the day and heads out together. We chose to take our XP1000 RZR out on to Steel Bender.

Got some great shots of the MB Quart Polaris products in Moab too. Since we were on the way to the booth and had to keep our RZR relatively clean, we took a slow roll to check out the neighborhood on the trail called “STEEL BENDER”.

Here are some more shots from our morning run.

Crawling up…

Coming down…

Stopping to cool our heels.. and our MSA Wheels with EFX rubber

Trails are brutal – Haha..  Thanks MSA and EFX for keep us sure footed.

The scenery at Rally on the Rocks cannot be properly visualized until you are sitting in your SXS under these incredible mountains.
