SB10-HDR4 kit features ACT's most popular Heavy Duty pressure plate. ACT Heavy Duty pressure plates use exclusive diaphragm design to increase clamp load, reduce deflection and maximize clutch life. All diaphragms endure a four-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stampings to provide rigidity and consistency. ACT's 4-pad rigid race discs are made with high quality, ceramic friction materials. The chrome-moly hub is heat-treated for strength and durability. The lightweight, rigid design allows for quicker shifts and smooth, trouble-free service. With the 4-pad rigid race disc engagement is harsher, but shifting is faster. The 4-pad rigid race disc is well-suited for the smaller disc sizes in smaller engines. Monoloc is a one-piece, direct replacement or upgrade to the standard, two-piece wedge collar and wire ring featured in pull-type clutches. The spring tension of the segmented retaining ring is carefully calculated and tested for optimal performance. It provides uniform loading on the bearing and pressure plate to assure proper alignment, regardless of driver influence or vehicle modifications. Monoloc's hardened chrome-moly steel construction will provide years of service.

This statement is only meant for customers paying using a credit or debit card. If you're using PayPal, Affirm, ApplePay, ShopPay Installments, etc. - no additional verification is necessary. It's best to use the billing address that's on file with the credit card company as the shipping address. We can ship orders to some shipping addresses that differ from the verified billing address. We realize some customers need orders shipped to their work address, college, or installation shop - these situations will result in minimal processing delays while we verify the information. However some orders that request shipping to an address other than the authorized credit card billing address may require additional verification and may be subject to processing delays. In an effort to protect the customer and our company from fraudulent transactions every order that is placed using a different shipping address will be looked at closely before the shipment is processed. If there is an unavoidable circumstance that requires an order be shipped to an address other than your billing address we will require customers to provide proof of credit card ownership. If your shipping address requires additional verification you will be emailed after placing the order.
