How much more does the HD EXEDY Stage 1 Organic Clutch hold than the standard kit?

EXEDY rates the 10803AHD at 310 lb-ft of torque capacity at the wheels against 248 lb-ft for the standard 10803A, because clamp load rises from 1,895 lb to 2,360 lb. Disc size and spline are the same, so the HD kit is a direct step up for a boosted Probe GT, MX-6 GT or RX-7 Turbo.

Will the HD clutch fit an FC3S RX-7 Turbo?

Yes. Turn 14 lists the 10803AHD for the 1986-1991 FC3S RX-7 Turbo and the 1988 10th Anniversary model. With the EXEDY ZF01 lightweight flywheel, Turn 14 calls for adapter and counterweight N327-11-521A on cars built before January 1989 and N351-11-521 on cars built after that date.

Is the HD Stage 1 clutch comfortable on the street?

Yes, with more pedal effort. The 10803AHD keeps the organic facing and sprung hub that make the EXEDY Stage 1 Organic Clutch engage smoothly, but its 2,360 lb clamp load asks more of the left leg in traffic. A stock-boost Probe GT or MX-6 will be lighter to drive on the standard 10803A.

Does the HD kit fit the Mazda 626?

Turn 14 does not list the 10803AHD for the 626, although it lists the standard 10803A for the 1988-1992 626 with the 2.2-liter engine. For a 626, choose the standard kit. The HD version is listed for the Probe GT, MX-6 GT, 929, B2600 and FC3S RX-7 Turbo only.

What is the difference between EXEDY Stage 1 and Stage 2 clutches?

EXEDY Stage 1 kits pair raised clamp load with an organic disc and sprung hub for smooth engagement. Stage 2 kits switch to a cerametallic disc that bites harder and holds more, with sharper take-up. The HD Stage 1 gives a modified Probe GT or RX-7 more capacity while keeping organic street manners.

Description

EXEDY Stage 1 Organic Clutch Kit for Ford Probe GT and Mazda 929, B2600, MX-6 and FC3S RX-7 (HD)

EXEDY’s Stage 1 Organic Clutch Kit for Ford Probe GT and Mazda 929, B2600, MX-6 and FC3S RX-7 in HD form raises clamp load to 2,360 lb, taking the rating to 310 lb-ft at the wheels. It is the choice for a Probe GT, MX-6 GT or RX-7 Turbo that has gained boost, where the standard kit would be working close to its limit.

Design and Performance

The HD kit keeps the 236 mm organic disc, sprung hub and 23-tooth spline of the standard 10803A and adds clamp load, 2,360 lb against 1,895 lb. EXEDY puts clutch torque capacity at 486 lb-ft and flywheel torque at 387 lb-ft, so the extra holding power arrives with a firmer pedal rather than a harsher engagement.

Features

Heavy-duty ductile-cast pressure plate, 2,360 lb
Organic facing on a sprung center hub
Shares the 23-tooth, 26.2 mm spline with the standard kit
Firmer pedal than the standard Stage 1
SFI 1.1 compliant, according to EXEDY

Specifications

Disc diameter: 236 mm
Input spline: 23 tooth, 26.2 mm
Clamp load: 2,360 lb
Clutch torque capacity: 486 lb-ft
Torque capacity at the flywheel: 387 lb-ft
Torque capacity at the wheels: 310 lb-ft

Applications

Ford Probe GT: 1989-1992 | L4
Mazda 929: 1988-1992 | 3.0L V6
Mazda B2600: 1987-1989 | 2.6L L4
Mazda MX-6 GT: 1988-1992 | 2.2L L4
Mazda RX-7: FC3S | 1986-1991 | 1.3L rotary (Turbo and 10th Anniversary)

Notes

On the FC3S RX-7, Turn 14 notes that the EXEDY ZF01 flywheel needs adapter / counterweight N327-11-521A on cars built before 1/89 and N351-11-521 on cars built after
Turn 14 does not list this HD kit for the Mazda 626; the standard EXEDY Stage 1 Organic Clutch Kit for the Probe GT and Mazda platforms covers the 626 and the vehicles listed here

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
