The TT01-E37/LB knuckle arm is produced as a direct replacement for the Tamiya TT-01 Type-E steering assembly. It maintains stock mounting dimensions and is intended for service use, restoring correct pivot positions and steering linkage alignment for competitive or club-level setups.
Installation follows standard procedure: remove wheel and hub, unbolt the existing knuckle from the suspension upright and steering link, then transfer bearings and retaining hardware. Ensure pivot clearances and bearing seating are correct to avoid play that could affect steering precision.
From a setup perspective the knuckle provides the rigid steering interface needed when tuning toe and scrub radius via tie rods and shock positions. It should be used as part of a wider suspension setup process rather than as an isolated performance upgrade. Verify alignment and torque values before track testing.
