Now we are talking STRONG. Why is it that the factories don't make ATV frames out of square tubing? Because square tubing BREAKS. JD Performance had designed the strongest swing arm on the market. With our exclusive "quad tube" design, the JD Swing arm has proven to be virtually unbreak able.
We invite you to order the JD swing arm and ride as HARD as you like!

Unmatched Strength

Our "Quad Tube" design has proven to have unmatched strength. While riding your quad, you are putting many different forces on your bike and the one part that takes most of the abuse is the swing arm. Twisting in the corners, compressing off a jump, and literally getting beat up in the whoops, you basically abuse this part more than any other part on your bike.

Each of the 4 tubes of the swing arms helps to disipate the pressure and divides the torsional forces and lowers the amount of stress that any one part of the swing arms must handle. It basically divides the work between the 4 tubes. All other aftermarket swing arms are made out of square tubing, that, let's face it, breaks. Using square tubing that enharently has weak spots (corners) and expecting it to handle multi-directional impacts simply doesn't make sense.

Custom Fit

These innovative swing arms have been expertly designed to fit all of the lastest Sport Quads on the market. Each of the bikes has it's own differences and we have pin pointed them and created a line of perfect fitting long lasting swing arms.

Exact Engineering

With our years of ATV building and extensive knowledge of suspension and drive train components, we have accurately determined what length would be best for each bike. Some bikes feel "heavy" in the front, while others are "wheelie machines". While this may be good while ripping up Glamis, it isn't always best on the MX track or GNCC National. Riding style and desired affects can be matched to the length of your swing arm to ensure that you get the most of out of your "Quad Tube" swing arm

With all extended length Swing Arms, JD Performance recommends that you get an aftermarket shock or adjust your stock shock as longer/short swing arms will affect the handling of your quad. Stock brake lines will work with +1 and +2 length swing arms, but longer brake lines will be required for any +3 or longer.
