DragonFire and “Weller Racing” ZR Performance Kits


What is the Truth About Weller Racing?

Proud owner a ’17 SS (the orange ones have the fastest! It’s a joy to ride it. A lifelong dirt-biker. Long-time quad owner (Grizzly 700), the change to a “cage”, was inevitable. So I brought this YXZ home, and made a few minor modifications. I was able to get a great deal on a Graves flash and pipe, and installed some Armor harnesses. My riding weller racing has been mostly in the high desert mountains, on old mining roads that were “widened” and single-tracked. The suspension was harsh from the very first ride. My wife didn’t like it so she wouldn’t be able to ride with me “going wild man”.

So I began to look on the internet and this Forum for great products for the YXZ. Many are more expensive than others and Reebok Hockey Skates many have different opinions on the best way to tune the suspension. It was also important to me that my YXZ cannot be fit in the toy hauler’s width. A widened long-travel system was therefore not an option. To get to the Meat and Potatoes, I narrowed down the list to a few companies based upon some comments I had read about customer satisfaction and after-sales follow-through.

DragonFire combined its winning years with Weller Racing to create a complete performance package that will work on the Polaris RZR. All you need, all pre-tuned, ready to go. This setup was developed by Weller Racing and DragonFire over a period of months. The RZR 1000 motor’s power is maximized by strategic focus on key components.

Adjustable shift weights are Weller’s secret to turning horsepower into traction. They allow for fine tuning power pulses and make it possible to convert them into power. A new helix allows for more back-shifting and better primary and secondary clutch springs.

The best part is that the DragonFire Performance Kit from Weller Racing delivers reliable horsepower. All components are adjustable so that the kit can grow as your RZR.
