Stronger springs for the fiber/steel clutch pack inside the clutch basket. The stock clutch springs do not provide enough clamping force to hold the extra torque produced from the lower reduction 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. The stage 2 springs are 125-150% stronger than the stock springs of various models. These are necessary when doing a primary reduction greater than 40%.
**These are not for DCT models, the DCT uses oil pressure for clutch holding.
