This rear spring pack is specified for LOSI Promoto-MX platforms and supplies three linear-rate 7075 alloy springs to refine rear suspension response. The design lets you alter overall spring rate without changing shock pistons or bodies.
The kit contains soft, medium and firm springs so you can trial different ride heights and rebound behaviours. Reference geometry from the supplier details coil counts and internal diameters to aid correct matching to shock shafts and retainers.
