The Tamiya 42278 TRF Damper Large Diameter Spring Set provides a straightforward way to adjust touring car suspension characteristics. Designed for TRF dampers, the set helps you tune handling for different circuits and conditions.
Included soft, medium and hard springs let you alter how the car responds to bumps and cornering. These coils have a larger inner diameter than Tamiya standard springs, measuring 14mm inside diameter, which contributes to a steadier feel on turn-in.
Colour-coded tubing is supplied so you can sort and identify springs quickly when changing setups between practice and race sessions, reducing errors under pressure.
For correct fit and secure installation, pair these springs with Tamiya Item 42192 TRF Damper Large Diameter Retainer (4pcs.), which is recommended for use with TRF large diameter setups.
