Set of 3 reinforced clutch springs Peugeot 103 SPX, RCX, CLIP & MVX (and others with DOPPLER clutch pulley)

DOPPLER hard clutch spring for Peugeot 103 spx, rcx, clip and mvx. It is also mounted on DOPPLER clutch pulleys of 103 SP, MV ... and MBK 51! This spring will allow you to hook the clutch very late in order to have the maximum power when hooking, therefore excellent acceleration. They are for original PEUGEOT pulley clutches (clutch pulley) but can very well be mounted on other pulleys. We also have softer springs for less efficient high speed engines and harder for even more high speed based engines!
