Our clutch baskets are CNC machined from the most durable aluminum available and we attach our patented "Second Generaton" stainless steel inserts which are 50% harder than before for extreme durability and to virtually eliminate grooving of the basket fingers . Precision machined oil passage windows allow more oil flow for cooler operating temperatures and longer clutch life. It all adds up to extremely smooth shifting and incredible durability even under the harshest conditions. For optimum performance, install a Dirt Digger Clutch Kit with your new basket!
