You will receive an email after placing this order to confirm freight and final shipping cost.

KLM builds the ZF 8HP51 in four stages, each based on a Dodson clutch package sized to your power goal.

Stage 1: Superstock (1,000hp / 1,000tq)

Dodson Superstock clutch kit. The entry build for cars pushing past factory clutch capacity, rated to a 1,000hp ceiling.

Stage 2: Sportsman (1,400hp / 1,200tq)

Dodson Sportsman clutch kit with high-coefficient frictions and tempered steels across all five clutch packs, and increased plate counts over stock for added holding capacity.

Stage 3: Sportsman Plus (1,500+hp / 1,300+tq)

Dodson Sportsman Plus kit for cars living at the top end of the 8HP51's envelope.

Stage 4: SAVAGE (1,700+hp)

Built on Dodson's new ProMax clutch package, developed for builds exceeding 1,700hp in roll and drag racing. The same ProMax platform we run and prove out in our own shop car, the car featured in Dodson's ProMax launch photos.

• Added friction plates across all five clutch packs with Dodson friction materials throughout
• Billet aluminum C hub and Dodson's steel-core splined E hub with aluminum outer, giving steel-hub strength without the rotating inertia that upsets shift behavior
• Hard anodized, chatter-resistant outer baskets with oiling holes to keep the denser clutch stacks at temperature
• Separator springs on the hard-working C and E clutches cut drag and keep takeoff and crossover smooth despite the higher plate counts, with no repeated adaptation learning
• Billet end plates and pistons give the A and D clutches rigidity under higher clamp pressure
• Billet steel A basket adds plates over stock to maximize torque holding in 1st and 2nd gear
• Pristine-finish high-grade alloy steels reduce wear and extend clutch pack life
