Kyosho 81mm Big Bore Front Shock Spring (Blue) (2) (8-1.5mm) #KYOIFS002-815

This is a set of optional Kyosho 81mm "Blue" Big Bore Front Shock Springs, and are intended for use with the Kyosho MP9 and MP10 1/8 scale buggies. These 81mm long front springs are recommended for rough tracks, or tracks with big jumps. These must be used with the longer 50mm shock (KYOIF484), and long front shock tower (KYOIFW623). Made with 1.5 diameter wire, these springs are more durable than the standard 1.4mm springs. Blue is the stiffest rate spring in the 1.5 wire 81mm spring lineup. 

NOTE: These springs must be used with the KYOIF484 50mm medium length shocks, and KYOIFW623 front shock tower.
