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

EXEDY rates the 05803AHD at 472 lb-ft of torque capacity at the wheels against 396 lb-ft for the standard 05803A. Clamp load rises from 3,012 lb to 3,597 lb, while the 240 mm disc and 23-tooth spline stay the same. That makes the HD kit the step for an Evo X with a turbo upgrade.

Does this clutch fit the Evo X MR?

No. The Evolution X MR uses a twin-clutch SST automated gearbox, so there is no conventional clutch for the 05803AHD to replace. Turn 14 lists this kit for the 2008-2015 GSR with the five-speed manual and the 2010 SE. A converted MR needs its gearbox confirmed before ordering.

Is the HD Stage 1 clutch comfortable on the street?

Yes, with more pedal effort. The 05803AHD keeps the organic facing and sprung hub of the EXEDY Stage 1 Organic Clutch, so take-up stays smooth, but the 3,597 lb clamp load is noticeably heavier than stock. An Evo X running only a tune will be easier to drive in traffic on the standard 05803A.

Should I choose the HD Stage 1 or a Stage 2 clutch for my Evo X?

Choose the HD Stage 1 if the car is driven on the street most of the time and makes less than its 472 lb-ft wheel rating. EXEDY Stage 2 kits use a cerametallic disc that holds more but engages more abruptly. The HD organic kit keeps launches and parking-lot maneuvers predictable.

How difficult is a clutch replacement on the Evolution X?

It is a transmission-out job on an all-wheel-drive car, with the transfer case and front driveline to work around, so a shop that knows the Evo X is the right choice. Inspect or resurface the flywheel at the same time, and check the release and pilot bearings while the gearbox is out of the car.

Description

EXEDY Stage 1 Organic Clutch Kit for CZ4A Mitsubishi Lancer Evolution X (HD)

EXEDY’s Stage 1 Organic Clutch Kit for CZ4A Mitsubishi Lancer Evolution X in HD form clamps at 3,597 lb and carries an EXEDY rating of 472 lb-ft at the wheels. It is aimed at the GSR that has gone past a tune to a larger turbo and fuel upgrades, where the standard Stage 1 would sit near its limit but a cerametallic disc would be too abrupt for the street.

Design and Performance

Against the standard 05803A, the HD version raises clamp load from 3,012 to 3,597 lb, lifting clutch torque capacity to 741 lb-ft and flywheel torque to 590 lb-ft. The 240 mm organic disc and sprung hub carry over, so the engagement character stays the same and the difference shows up mainly as pedal effort.

Features

Heavy-duty ductile-cast pressure plate, 3,597 lb
Organic facing on a sprung center hub
Rated 590 lb-ft at the flywheel by EXEDY
Same 240 mm disc and spline as the standard kit
SFI 1.1 compliant, according to EXEDY

Specifications

Disc diameter: 240 mm
Input spline: 23 tooth, 26.2 mm
Clamp load: 3,597 lb
Clutch torque capacity: 741 lb-ft
Torque capacity at the flywheel: 590 lb-ft
Torque capacity at the wheels: 472 lb-ft

Applications

Mitsubishi Lancer Evolution X: CZ4A | 2008-2015 | 2.0L turbo L4 (GSR and SE)

Notes

Fits the five-speed manual Evolution X GSR; the MR uses a twin-clutch SST gearbox and does not take this kit
For a lighter pedal on a tuned but otherwise stock car, choose the standard EXEDY Stage 1 Organic Clutch Kit for the Evolution X

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.
