What is in the TS3B Overhaul Kit B for JZA80 kit?

The TS3B Overhaul Kit B for JZA80 kit contains all 3 clutch discs, the center plates, the pressure plate and a set of cover bolts, plus a new clutch cover. Overhaul Kit A has the same parts without the cover, for clutches where the original cover is still in good condition.

Should I choose Overhaul Kit A or Overhaul Kit B?

Choose Kit A when the existing TS cover is in good condition, with no heat damage and a healthy diaphragm, because it costs less and reuses a part that still works. Choose Kit B when the cover shows wear or heat marks, or when the clutch has seen enough use that a full refresh makes sense.

Will this kit rebuild a different OS Giken clutch?

No. This kit is matched to the TS3B clutch, part number TY031-CC3, for the JZA80 Supra. Other OS Giken series use different covers, discs and plates, and each has its own overhaul kit, so the kit should always match the clutch part number.

How do I know my clutch needs rebuilding?

The usual signs are slip under full load, an engagement point that has moved, or new judder on take-off. Wear depends heavily on launches, track use and power level, so there is no fixed interval. When any of those signs appear, a rebuild with fresh discs and plates restores the original behavior.

Does it also rebuild the TS3BW?

No. The TS3BW is a separate clutch, part number TY031-CD3, with its heavier flywheel, and OS Giken lists its own overhaul kits for it. This Kit B is matched to the TS3B, part number TY031-CC3. Order the kit by the clutch part number.

Description

OS Giken TS3B Overhaul Kit B for JZA80 Toyota Supra 2JZ-GTE, Triple Plate

OS Giken’s TS3B Overhaul Kit B for JZA80 Supra clutches is the full rebuild for the TS3B triple plate clutch: all three 204mm discs, both center plates, the pressure plate, the cover bolts and a new TS cover. A triple plate clutch has more friction faces than a twin plate, and replacing them together restores the clamping behind the roughly 700 lb-ft rating OS Giken USA gives the TS3B. Kit B suits a clutch that has worked hard enough, or long enough, that the cover deserves replacing too, and it returns the stack to new condition in one job.

Replacing the Whole Stack

Because every disc and plate in a triple plate stack shares the clamp load, replacing them together keeps engagement even. Kit B adds the cover with a fresh diaphragm spring. If the original cover is still flat and clamping evenly, OS Giken’s Overhaul Kit A for this clutch (TY031-CC30A) reuses it for less.

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.
