JD Performance A-arms are built for the top class racers.
Camber Adjustment On these A-arms, the ball joint slides through the end of the arm, with a jam nut on the outside and lock nut on the inside. Camber adjustment is done by simply loosening one nut and tightening the other. Most of the competition threads the top ball joint into the arm, so adjusting the camber would require "breaking" the ball joint loose from the spindle then turning the ball joint... not very fast or easy. For those of you who are worried about the jam nut on our set up, simply use a little Locktite.
Caster Adjustment Setting the caster is the fastest and easiest in the industry. The top arms have "caster shims". Simply remove the top A arm bolt (or 2 bolts for non Yamaha) and relocate the shims and shift the arm forward or back. The whole process takes 5 to 10 minutes, and adjusting the caster does not affect your camber settings. Most of the competition uses heims on the frame end of the top A arms to adjust caster. Using this method is extremely time consuming and difficult to do, not to mention that your camber settings will change in the process. Getting both sides of your quad to have equal settings is nearly impossible without specialized gauges and tons of experience. JD has taken the guess work out of the front end and made it easy for you!
The caster adjustment on these arms are innovative, quick and EXACT everytime.
JD Long Travel A-arm Kit This kit includes the items needed to do a basic install. Here is what it includes:
Width: The wider your go, the more stable the quad becomes. The suspension also gains wheel travel when you widen the stance.
Forward: The forward position is determined from the stock location. Depending on the rider, bike and type of riding, some people want to change the forward position of the A-arms to help keep the front end down , balance the weight of the quad or add bite in a corner.
**ATTENTION RACERS - If you are purchasing A-arms for racing, be aware that +3 a-arms on most ATVs may put the width of your ATV over the regulation limit. If you are running negative offset front wheels (4+1) then you may be able to run +3 A-arms. Please be aware of the regulations, know your equipment and do your homework before ordering.
