TRF Sh. Damper Spring Medium, RC spring set

The TRF Sh. Damper Spring Medium adds a focused suspension tuning option for compatible RC chassis, using a medium spring rate and a free length about 5 mm shorter than the hard spring from the OP440 street specification. That shorter length lowers vehicle height, which supports added stability during higher-speed running and gives setup work a more planted base. This set contains 2 matching coil springs and is intended for use with Item 53571 TRF Damper Set with fluorine-coated dampers. Across compatible FF, M, TA, TB and TT chassis, the spring choice broadens the available adjustment range when combined with other springs in the setup. The yellow finish makes the pair easy to identify on the bench or during maintenance, while the matched format suits left and right damper installation on the same car. Compatibility includes FF-03, FF-03 PRO, FF-04 EVO, M-07 Concept, TA05 Ver.II, TA06, TA06 PRO, TA06 MS, TA07 PRO, TA07 MS, TB-03, TB-03 VDS, TB-04, TB-04 PRO, TB-05 PRO, TT-01 Type-E, TT-01 Type-ES, TT-01D Type-E, TT-02, TT-02D, TT-02 Type-S and TT-02RR chassis. On a tuning bench or at the track, this spring pair supports quick suspension changes when a lower ride height and a different damping balance are needed.
