How much torque does the HD EXEDY Stage 1 Organic Clutch hold on an Evo VIII or IX?

EXEDY rates the 05803HD at 472 lb-ft of torque capacity at the wheels, 590 lb-ft at the flywheel and 741 lb-ft of clutch torque capacity, from a 3,597 lb clamp load on a 240 mm disc. That suits a 4G63 Evo with a larger turbo and supporting fuel work that is still driven on the street.

Does this kit fit the Evolution MR, RS and SE models?

Yes. Turn 14 lists the 05803HD for the 2005-2006 Evolution MR and RS, the 2006 SE and the standard 2003-2006 cars. All of them share the 23-tooth, 26.2 mm input spline the 240 mm disc is built around. If the car has had a gearbox swap, confirm the input spline before ordering.

Is the HD Stage 1 clutch comfortable for daily driving?

Yes, with a heavier pedal. The 05803HD keeps the organic facing and sprung hub of the EXEDY Stage 1 Organic Clutch range, so take-up stays smooth, but 3,597 lb of clamp load asks for more effort than the factory clutch. Owners who sit in heavy traffic every day will notice the difference.

Why does Turn 14 mention the Evolution IV for this clutch?

Turn 14 titles the 05803HD for the 1996 Lancer Evolution IV, a model never sold new in the US, while its fitment table lists the 2003-2006 Evolution VIII and IX. We list those US applications. Owners of imported earlier Evolutions should contact us to confirm the input spline before ordering.

How difficult is a clutch replacement on the Evo VIII or IX?

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 CT9A 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.

Description

EXEDY Stage 1 Organic Clutch Kit for CT9A Mitsubishi Lancer Evolution VIII and IX (HD)

EXEDY’s Stage 1 Organic Clutch Kit for CT9A Mitsubishi Lancer Evolution VIII and IX in HD form clamps at 3,597 lb and is rated by EXEDY at 472 lb-ft at the wheels, for the 4G63-powered Evos sold in the US from 2003 to 2006. It carries the extra load of a turbo and fuel upgrade while keeping an organic disc that stays civil in daily use.

Design and Performance

EXEDY lists 741 lb-ft of clutch torque capacity and 590 lb-ft at the flywheel for this HD Stage 1 Organic Clutch, from a ductile-cast pressure plate clamping a 240 mm organic disc. The sprung hub matters on the CT9A, whose all-wheel-drive driveline sends sharp shocks back through the clutch on launches; it softens them without the chatter a puck disc brings.

Features

Heavy-duty ductile-cast pressure plate, 3,597 lb
Organic disc on a sprung center hub
Rated 741 lb-ft of clutch torque capacity by EXEDY
Sized for the 4G63 Evolution VIII and IX
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: CT9A | 2003-2006 | 2.0L turbo L4 (VIII and IX, including MR, RS and SE)

Notes

Turn 14 also titles this part for the 1996 Lancer Evolution IV; its US fitment table lists the 2003-2006 Evolution VIII and IX
Turn 14 also shows a 2007 Lancer ES row, left out here because the ES is a non-turbo front-drive car without the Evolution drivetrain

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.
