This is the optional Yokomo Aluminum YD-2/YD-4 Adjustable Rear H Arm Kit. This all new rear H arm kit is made of aluminum with Yokomo original high precision processing to enable drivers to make adjustments to chassis tread for finding out the best chassis balance, and also for the best width to suite your body style of choice.
Adjustable length for each side will be -2.0mm (without any spacers) up to 1.5mm (3 spacers) by adding 3 spacers (0.5mm, 1.0mm, 2.0mm) as standard bundled with kits.
Realistic maximum length will be 6.0 to 7.0mm to keep the necessary rigidity. Longer universal bones need to be prepared separately and be purchased separately. As for removing/inserting spacers, it is possible during the time of competition, delivering the ease on tweaking your car chassis tread on the fly at a RC drift competition.
