Does the TR2CD Clutch for JZA80 need anything else to fit?

Yes. The TR2CD Clutch for JZA80 is a push-type clutch and the JZA80 six-speed uses a pull-type release from the factory, so it is installed with the OS Giken Movement Alteration Kit for JZA80 (TY031-ALT). Turn 14 lists a kit as required; our team can confirm the pairing before you order.

How much power will it hold?

OS Giken USA rates the TR2CD at about 800 lb-ft of torque, reliably, and OS Giken Japan places the TR series in its 600 PS class. It is meant for heavily modified turbocharged engines. For engines beyond that, the R series race clutches are the next step.

What does TR2CD mean?

It is the OS Giken model code. TR is the cover series with the billet aluminum cover, 2 is the number of discs, C is the 215mm disc size and D means the discs have damped hubs to soften driveline shock and protect the gearbox.

The aluminum cover gives a more direct feel, but OS Giken designed the diaphragm spring geometry to reduce overall pedal effort. Expect a firmer pedal and engagement than a factory single plate, but one that is still usable on the street.

Can it be rebuilt when it wears?

Yes. OS Giken Overhaul Kit A replaces the discs, center plate, pressure plate and cover bolts, and Overhaul Kit B adds a new cover. Rebuilding with the matching kit restores the clutch for less than buying a complete new kit.

Description

OS Giken TR2CD Clutch for JZA80 Toyota Supra 2JZ-GTE, Twin Plate

OS Giken’s TR2CD Clutch for JZA80 builds is the twin plate kit OS Giken designed for turbocharged engines with a substantial increase in power, which makes it a natural match for a heavily modified 2JZ-GTE. Its billet aluminum cover gives a more direct pedal feel and allows a higher clamping force than a pressed-steel cover, while the geometry of its diaphragm spring keeps pedal effort manageable. The two 215mm discs use damped hubs, and OS Giken USA rates the kit at about 800 lb-ft, reliably. It is built to take the hard use a track or drag Supra sees.

Aluminum Cover, Higher Clamp

The TR series is where OS Giken moves from pressed steel to a billet aluminum cover. OS Giken USA credits that cover with the higher clamping force behind the 800 lb-ft rating and with handling the abuse found at the track. OS Giken Japan places the TR series in its 600 PS class, above the TS line and below the R series race clutches.

Billet aluminum cover for higher clamping force
Two 215mm discs with damped hubs
Rated by OS Giken USA at about 800 lb-ft

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.
