Will the Super Lock LSD for 1NZ Yaris fit an automatic car?

No. The Super Lock LSD for 1NZ Yaris is listed for manual-transmission cars only, including the NCP13 Vitz RS. Automatic Yaris and Vitz models use a different transaxle and differential case, so check the transmission before ordering. If in doubt, send us the VIN and we will help confirm the fitment.

Which US Yaris models does it fit?

Turn 14 lists the 2007 to 2014 US Yaris with the 1.5-liter 1NZ-FE engine and a manual gearbox. OS Giken USA names the 1NZ Yaris. Confirm your transmission code with your installer or our team before ordering to be sure the case matches.

Will a plate LSD cause torque steer?

Any front-drive LSD adds some steering feel under hard throttle because it sends more torque to the wheel with grip. The Super Lock builds lock progressively, which keeps that effect predictable, and most drivers adapt quickly once they feel the gain in corner exit traction.

Is it suitable for a daily driven Yaris?

Yes. The pressure ring design is built for smooth, progressive locking rather than an abrupt grab, so it can be driven on the street. Expect some noise and a different feel at full lock in tight parking maneuvers compared to the factory open differential.

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 track use. Fresh oil keeps the friction plates working consistently, reduces chatter and helps the unit last longer between rebuilds.

OS Giken Super Lock LSD for 1NZ Yaris and Toyota NCP13 Vitz Manual

OS Giken’s Super Lock LSD for 1NZ Yaris replaces the open differential in manual-transmission Toyota Yaris and Vitz models powered by the 1.5-liter 1NZ-FE engine, including the NCP13 Vitz RS. A small front-drive car lives or dies by how well it puts power down out of tight corners, and an open differential lets the unloaded inside wheel spin away the drive the moment the car is turned and loaded. The Super Lock is a plate-type limited-slip differential that ties the front wheels together progressively, so the car pulls itself out of the corner instead of scrabbling at the inside tire. It suits autocross, track day and grassroots racing Yaris builds.

Why a Plate LSD on a Small Front-Drive Car

Light front-drive cars carry little weight on the inside front tire mid-corner, which is exactly where an open differential sends drive. A clutch-type LSD transfers that torque to the wheel with grip, which also lets the driver get back to throttle earlier and more firmly on corner exit.

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.
