Tamiya TT-01 Type-E Knuckle Arm by 3Racing TT01-E37/LB  [TT01-E37/LB]

TT-01 Type-E knuckle arm overview

This knuckle arm is an RC-scale replacement part produced under 3Racing's TT01-E37/LB designation for use with Tamiya TT-01 Type-E chassis. It serves as a direct service item for the steering knuckle, intended to replace a worn or damaged original unit and to support basic tuning tasks related to steering geometry.

Installation requires basic RC maintenance skills: remove the wheel and hub assembly, detach the existing knuckle from the suspension upright and steering link, then transfer bearings and hardware to the replacement as needed. Standard TT-01 Type-E steering linkages and mounting points are used, so no chassis modification should be necessary when fitment is correct.

For tuning, this knuckle arm is useful when adjusting toe and scrub radius through associated suspension components; it functions as a structural steering interface rather than a performance upgrade by itself. Confirm alignment and fastener torque after installation and test in a controlled environment before running at higher speeds.
