F101/102 Rear Coil Spring for Tamiya 5005032 58174/118  [5005032]

Rear spring for F1-style rear suspension

This rear coil spring is an RC-scale replacement intended for the rear suspension of compatible F1-style Tamiya chassis. It carries the internal designation 58174/118 and is used to restore or change rear suspension response without altering the shock body itself.

Fit this spring when replacing worn rear springs or when fine-tuning rear-end behaviour for balanced handling. Typical installation requires removing the rear shock assembly, swapping the spring, and refitting the same shock cap and spring retainer; only standard RC hand tools are normally required. Always confirm physical fit with F101/102 Group C F1-style mounting points before completing installation.

When tuning, pair spring changes with adjustments to shock oil, preload, and mounting position to dial in roll and traction. Record setup changes so you can reproduce preferred configurations for different track surfaces and conditions.
