The Roll Design Long Travel ATV A-Arms for the HONDA TRX400EX feature the notoriously strong gull wing design mated with the over-sized 4130 chromoly construction. The inboard pivots use PFTE composite-lined bearings with precision-ground pivot pins crafted from hardened steel. The upper control arms feature fully-adjustable caster and camber through the use of its three-piece, high-misalignment design. These misalignment spacers are the best in the business, manufactured from 17-4 stainless steel. This is the very same stainless steel used in mission critical aerospace and nuclear reactor applications for superior strength and corrosion resistance. The replaceable rod ends are lined with long-wearing Teflon. The top and bottom arms are equipped with high-angle ball joints that are sealed and replaceable. These ball joints are en-captured in the arms to eliminate any potential sheer point, ultimately increasing reliability.
