The Centerforce ® Dual Friction ® Clutch Series is a performance matched pressure plate & disc combination featuring the patented Centerforce centrifugal weight system (where applicable) and specialized machining processes to provide a performance clutch that offers exceptional street characteristics, while offering outstanding holding-capacity and durability. Furthermore, the Centerforce Dual Friction disc has an organic full facing on one side for longevity and an organic segmented facing on the other side providing increased holding capacity. Some applications have the organic segmented facings of both sides.

The Dual Friction clutch is engineered for those who are looking for the ultimate in street/strip holding power and performance without sacrificing pedal effort and driver control. While the Dual Friction has been engineered primarily as a street clutch it can be used in mild competition applications.

Return Policy


At Centerforce our mission is to provide you with the best products and the best service in the industry. We understand that sometimes, customers change their minds about products that they order or simply do not need them anymore. We also know that customers are cautious about Return Policies since they are often tricky and misleading. Our goal is to make the return or exchange process trustworthy and as simple as 1-2-3.


If for any reason you are not completely satisfied with your purchase, you may return the item within 30 days of delivery of your order. For orders placed during the holiday season from November 15th to December 31st, the return period is extended to 60 days.

The following rules apply:

Products must be in original packaging and in a new and resalable condition.

Any product that was used or fully/partially installed is non-returnable. If the product has been installed, or is past the 30 day return period please see the Centerforce Limited Warranty in Terms of Use and call (800) 932-5882.

Shipping Fees are non-refundable

(In the instance there is free shipping the value of the shipping will be deducted from the credit to the customer).

All returns must be made via our Return Procedure by filling out an RMA form in the MY ACCOUNT section.

Order cancellations can only be requested prior to shipment.


To return a product, you must first request a Return Merchandise Authorization (RMA) that is located in the MY ACCOUNT section next to each order item that you want to return. The RMA form will include an exact return address and detailed instructions on how to return a product. Upon receipt please allow up to 10 working days after the item has been received for processing your claim.


There are 2 ways you can go about exchanging a product:

Option 1 (Slower) - Use the standard return procedure to request an RMA for the part you need exchanged. In your request please specify the exact item(s) you would like to exchange to. Upon receipt of your returned product we will process an exchange and ship the new part. If there is a difference in the price, you will be either refunded or charged the difference.

Option 2 (Faster) - Order the new part online or over the phone at (800) 532-5882 so it can be shipped to you right away. Then request an RMA using a standard Return Procedure for the part you would like to return. Upon return of the part a refund will be issued promptly.


We know that accidents happen sometimes. If your product(s) arrive defective, damaged, or packaged incorrectly, please contact our customer service department as soon as possible. Please do not attempt to use or install the part! Product(s) must be returned to us within 30 days. If the damage was caused by a shipping courier, we will schedule a damage pick up by the courier.

When a replacement part is requested to be shipped prior to the return of the original merchandise, we must temporarily authorize your credit card until the original merchandise is returned or 30 days whichever comes first.


When you request a cancellation of an order or a part it may take up to 72 hours to process your cancellation claim. This process may involve voiding orders in computer systems, removing items from backorder logs, having operations personnel pull items from production schedules and sometimes stopping orders at the shipping dock. Also note that sometimes products ship more quickly than expected, so we recommend that you do not purchase alternative products until receiving final confirmation of your cancellation.


After we accept your return, you will be issued a refund via the same payment method as you had originally used to place the order. The refund amount will be composed of the original purchase price minus shipping charges. If free shipping is offered the shipping charges will be deducted from the refund amount also. You will be sent an email confirming receipt of the return and your credit. Please allow an additional 5-7 days for the credit to appear on your account.
