Do you want to boost the performance of your Polaris RZR XP 1000 without sacrificing reliability? Dragonfire Racing has done it again, creating a product that not only sounds good on paper but also that looks good and performs even better. The guys at Dragonfire Racing went to work combining years of creating quality performance parts and accessories with the knowledge and proven success of the Weller Racing group to help create a package designed to boost the power of your Polaris RZR, the Dragonfire Stage 1 Performance Kit by Weller Racing.

The kit includes everything your SxS needs to get every last pony out of your stock machine, it has taken quite some time developing, testing and tuning products to gain an approximate 5% increase over stock levels. The key component of the kit is the DragonFire PyroPak Fuel management software that works in conjunction with the Air Raid High Flow Air filter. By accommodating more air you can boost fueling, making extra power that is transferred to the ground via the upgraded clutch components.

Those components are Weller Racing’s secret to converting horsepower in to traction, the adjustable shift weights makes it possible to fine tune power pulses. Combined with the beefier heavy duty primary and secondary clutch springs, the kit offers improved shift points to your XP1K.  Additionally, like any Dragonfire product, it’s designed to last over the long haul and not be a strain on an otherwise stock UTV.
