Description

Since the genuine reading / trailing arm is made of cast iron, which has a relatively low cost, it may bend or break in the worst case if it is subjected to intense cross-country driving. If the arm breaks, not only will it not be possible to move according to the road surface, but the coil spring will come off or the propeller shaft will come off, causing a very dangerous situation such as an inability to drive or a fall due to a change in behavior.
The HD Red Arm is made of sturdy drawn carbon steel pipe (STKM11S), so the sheer force is as high as about 20 times the axle load.

The bush for HD red arm is basically used by recombining the genuine arm bush, but it is recommended to use it together with the pillow bush or rubber bush.

* The caster angle of the leading arm (front) is designed to be corrected to 1 degree 30 minutes plus when using a genuine bush. Therefore, if the caster angle is increased by 40 mm, the caster angle will be almost the same as the genuine one, so it will be corrected to the proper state without using the eccentric bush. With 75mm up, using one eccentric type bush will be equivalent to genuine.
