This knuckle arm, labelled TT01-E37/LB, is an aftermarket replacement intended for the Tamiya TT-01 Type-E chassis. It replaces a damaged steering knuckle and preserves the original mounting pattern for simple installation and reliable steering linkage connection.
To fit the part, remove the wheel and hub assembly, detach the old knuckle from the upright and steering rod, then move bearings and any required hardware across. The knuckle uses the stock Type-E mounting locations so no cutting or extra brackets should be necessary when aligned correctly.
Use the knuckle when adjusting toe or scrub radius via the suspension setup; it is a service component that enables tuning through other suspension parts rather than providing an independent performance boost. Recheck toe settings and fastener tightness before running the car aggressively.
