  • Lock and load your RZR XP 1000 and get ready for some serious kick!  The RZR XP 1000 is a great machine, but Polaris left a ton of room for improvement on any year machine.  This simple kit is the best way to wake up your XP 1000 as it comes with our proven ECU tunes which are loaded via the PVCX ECU tuner.  The tunes add some amazing horsepower from low end to high end RPM's, and really give your machine that "snap" you're looking for.  The clutching compliment the tuning perfectly by better transferring the power to the wheels and ridding yourself of the very lazy factory clutching setup.  
  • Fits 2014-Up RZR XP 1000 Models, 2 & 4 seat
  • Kit includes the AA custom tuned PV3 tuner & the correct S2 clutch kit for your year
  • Big gains in performance from 7-9 HP
  • Big mid-range punch makes this kit feel like it gains even more than advertised
  • Tuner flashes in minutes and allows you to switch tunes or go back to stock at any time
  • Tuner can be mounted for gauges or removed after tuning
  • Tuner includes 1 tune with the base kit price.  Other tunes can be added for $50 each
  • The Level 1 tune is a huge increase and is developed for the stock exhaust (cat removed is okay)  This is seriously worth every penny!  You are looking at an average 6-9 HP gain on pump gas with the tune, but the down low grunt is absolutely awesome.   
  • The Level 2 tune has all the same benefits as Level 1 but with increased fueling for a slip-on or full exhaust system. Together with a tune and exhaust you can see 11-14 RWHP gains! 
  • Race fuel tune 95+ octane maxes out our timing curve to where we see peak power.  This gives you another 3-4rwhp on average over the pump gas tunes.
  • Wicked throttle response and quicker back shifts when in/out of the throttle
  • More consistent clutch performance
  • Adjustable clutch weights (magnetic adjustable) with a great setup guideline
  • We offer two clutch kits:
    • Standard Load:  The Standard Load clutch kit is meant for stock or near stock size tires  (28-30") and is the one for most fast pace trail riders or racers.  
    • High Load: The High Load clutch kit is meant for those with larger tires (31-32"), mud  tires, dune riders, and those with paddles 28" or larger.  Mudding and dune riding are considered high load and must be clutched slightly different. If planning to run 34-35" tires on stock gearing please contact us about a stiffer secondary spring.
    • Engine  Braking Option:  Choose between keeping engine braking like factory, or  removing it.  Most fast pace trail riders/racers or dune riders will choose to remove it.  Most slower pace riders like mud, crawling or very hilly terrain will keep the EBS in place.

Check components for imperfections
Color: Black, Color: Black
Just finished putting the chair together, and while there were some nice touches (gloves to wear while assembling) and manual very easy to understand, there are more steps than are customary for a basic chair. However, two main gripes are (1) bought Saturday for $129.99, today it is listed for $89.99 (2) out of the box, the mesh back of the chair has a small tear in it. Unsure if it will end up being a long-term issue, but irritating all the same.

Amazing chair
Color: Black
Going from a regular office chair to this majestic heavenly office chair, my body hasn't felt better. As a person who is rather on the large side (6'2, 175 pounds), so this chair good butt cushioning, adjustable armrest, the adjustable headrest made this purchase an very good one. I move constantly on chairs so when i found out tthis chair can adapt to my position with a few tweaks i instantly fell in love. Considering that I have jumped and stood on the chair quite the number of times and it still is holding its form just speaks to its sturdiness. I dont believe in buying extremely expensive chairs as a high quality one like this has everything you could wish for.

Wow Great Deal!
Color: Black
I have been using this chair for a month now and I am honestly impressed for the price I paid. I work from home so am using this chair 24/7. I had no issues with assembling it myself as a 35 year old female. Instructions were simple to follow and took me maybe 30 minutes to put together. Its sturdy and comfortable. I appreciate the padded arms and the seat bottom is also a nice thick cushion. Added bonus for the head rest and that it is adjustable. Definitely recommend.

Very comfortable office chair
Color: Black
This ergonomic office chair is very comfortable and has good lumbar support and a nice headrest. It includes all the necessary tools and takes about 20 minutes to fully assemble. The height adjust and recline features of the chair work smoothly and quietly. The seat cushion is nice and comfortable. The height-adjustable armrest is also a nice features of the chair. Overall, this ergonomic office chair provides relaxing comfort during long hours sitting with support for your bottom, back, head and arms. It's a good value for the price.

Good quality and arrived quickly
Color: Black
I was very pleased with how easy this chair was to set up. Affordable, arrived quickly. The only reason it isn’t 5/5 is because on of the arms had a small dent, possibly due to not enough bubble wrap during shipping. Other than that, the quality is great.
