Which cars does the Super Lock LSD for Y34 Cedric fit?

The Super Lock LSD for Y34 Cedric is listed by OS Giken and Turn 14 for the Y34 generation Nissan Cedric with an automatic transmission. The Y34 Gloria shares much of its platform, but confirm the rear differential with OS Giken before fitting it to any other car.

Is it suitable for drifting?

Yes. A plate-type LSD keeps both rear wheels driving together, so the car holds a steady angle and transitions predictably. OS Giken can also retune the unit with different springs and ramp angles if a drift build needs a stronger or faster lock.

Will it be noisy on the street?

Plate-type differentials can make some noise and chatter during tight, slow turns such as parking. The Super Lock pressure ring is designed for smooth, progressive locking, and using the right oil and changing it on schedule keeps noise to a minimum.

Can OS Giken tune it for my car?

Yes. OS Giken retunes Super Lock units in-house. Cone springs set initial torque, pressure ring springs set how quickly full lock arrives, and the pressure ring and iron cross set the ramp angles, so the unit can be matched to weight, power and use.

What oil should be used?

Use a gear oil suited to clutch-type limited-slip differentials, and change it more often than with an open differential, especially after hard use. Fresh oil keeps the friction plates working consistently, reduces chatter and helps the unit last longer between rebuilds.

Description

OS Giken Super Lock LSD for Y34 Cedric Automatic (Nissan)

OS Giken’s Super Lock LSD for Y34 Cedric is a plate-type limited-slip differential for the automatic-transmission Nissan Cedric of the Y34 generation, a rear-drive Japanese-market luxury sedan powered by a VQ-series V6. The factory open differential sends drive to whichever rear wheel has the least grip, so a big sedan with a healthy V6 lights up the inside tire coming out of a corner or on a damp road. The Super Lock ties the rear wheels together progressively, putting the power down evenly and making slides predictable and repeatable. It is built to suit both a fast street car and a dedicated drift chassis.

Built for Heavy Rear-Drive Sedans

A large sedan carries more weight through the rear axle under power than a small sports car, which asks more of the differential. The Super Lock fits more friction plates than competing designs through its spline-through-side-gear construction, spreading that load across a larger clutch area.

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.
