*Stock sized secondary chains, regardless of brand, will not last with the increase in spring rate and nose pressure. You MUST run an aftermarket big chain secondary drive or you will have a secondary chain failure at some point. 
We highly recommend using RGR Secondary Chain, Sprocket and Tensioner Kit with these springs.
 
 
Please see Spring Spec Chart for complete pressures and details.
