Which cars does the TCD LSD for W211 E55 fit?

OS Giken Japan lists the TCD LSD for W211 E55 models for the W211 E55 and E63, W219 CLS55 and CLS63, W204 C63, W209 CLK63, W221 S63, W216 CL63 and R230 SL550, SL600 and SL65. Turn 14 lists the 2003 to 2006 E55, the 2006 CLS55 and the 2007 to 2008 CLK63.

What makes a TCD different from a Super Lock LSD?

TCD uses the Super Lock mechanism, but the friction discs carry oil holes and channels that keep them wet. That lets the unit switch between open and locked smoothly and quietly, which suits a powerful road car while still giving the traction of a plate-type LSD.

Does it fit the W210 E55?

No. OS Giken Japan lists the earlier W210 E55 under the Type-E unit, which is listed separately. Check the chassis code of your car before ordering, and contact our team if you are unsure which type it needs. We can confirm it with OS Giken.

Can the cam angle be changed?

Yes. OS Giken can set the cam angle of a TCD unit, which changes how strongly it locks under power and on deceleration. Tell our team how the car is used and we can pass the request to OS Giken when ordering.

What oil should be used?

Use a gear oil suited to clutch-type limited-slip differentials. OS Giken makes a dedicated LSD gear oil for its units. Change the oil more often than with an open differential, since fresh oil keeps the discs working smoothly and quietly between services.

Description

OS Giken TCD LSD for W211 E55, W219 CLS55 and AMG 63 Mercedes-Benz

OS Giken’s TCD LSD for W211 E55 and related AMG models is the Type-C unit in OS Giken’s Mercedes-Benz range, the one that covers the widest spread of supercharged and naturally aspirated AMG V8 sedans and coupes. OS Giken Japan lists it for the W211 E55 and E63, W219 CLS55 and CLS63, W204 C63, W209 CLK63, W221 S63, W216 CL63 and the R230 SL550, SL600 and SL65, all automatic. TCD is OS Giken’s comfort-oriented mechanical limited-slip differential on the Super Lock mechanism, with oil holes and channels in the friction discs that keep them wet so it locks smoothly and quietly. With this much torque at the rear axle, it keeps both rear tires driving out of corners.

Fitting Notes From OS Giken

OS Giken Japan lists machining as required on the W219 CLS55 and CLS63, and no special work on the other Type-C cars. On the W221 S65, the type depends on the car, so the chassis number must be checked. Fitting should follow the factory service manual for the specific model.

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.
