The GPM DF1056 rear suspension arm is an engineered aftermarket replacement for the Tamiya DF01 chassis, supplied as 1pr to ensure matched left and right components. This technical note focuses on fitment, installation best practice, and its role in restoring OEM rear geometry without specifying material changes or performance gains.
Fit notes: the DF1056 is intended to substitute worn or fractured rear lower arms while preserving stock geometry and mount points. Removal of the rear hub carrier and control arm fasteners is required for installation; use appropriate hex drivers and controlled torque to prevent damage to pins and threaded holes.
Tuning and service: replacing rear arms is a standard repair to recover precise suspension geometry after impacts. After fitting, confirm pivot clearance and ball stud seating to ensure repeatable handling characteristics.
Install this arm to restore correct DF01 rear geometry; verify secure fastener torque and pivot retention during reassembly.
