Stiffer springs for the change clutch basket. The stock clutch springs do not provide enough clamping force to hold the extra torque produced from the lower input ratios. Our stage 1 springs are 50-75% stronger than the stock springs of various models. These are ideal for our 20% and 40% primary reductions.
