What does the Movement Alteration Kit for R34 R3C clutch installs do?

The Movement Alteration Kit for R34 R3C clutch installs lets the push-type OS Giken R3C triple plate clutch work with the pull-type release system the BNR34 GT-R had from the factory. Without it, the factory release cannot operate the clutch.

Do I need it if I already have a pull-type aftermarket clutch?

Only if you are fitting the OS Giken R3C, which is a push-type clutch. Turn 14 lists this kit as required with that clutch on the BNR34. Other clutches have their own requirements, so check the part number of the clutch you are installing.

Can I use it with another brand of clutch?

No. OS Giken states that its Movement Alteration Kits are designed to work with OS Giken clutches, and that using one in an unintended application can cause clutch components to fail. Use it only with the OS Giken clutch it is listed for.

Is it the same kit as the one for the R4C?

No. OS Giken and Turn 14 list a separate Movement Alteration Kit for the R34 R4C quad plate clutch. Each kit is listed for one clutch, so match the kit to the part number of the clutch you are installing, and contact our team if unsure.

Should it be installed with the clutch?

Yes. The kit changes how the release system operates, so it goes in at the same time as the R3C clutch. Have both installed by a shop familiar with multi-plate clutches and the BNR34 drivetrain, and follow the instructions supplied by OS Giken.

OS Giken Movement Alteration Kit for R34 R3C Clutch, Nissan Skyline GT-R

OS Giken’s Movement Alteration Kit for R34 R3C clutch installs is the part that lets the push-type OS Giken R3C triple plate clutch work in the BNR34 Skyline GT-R, which left the factory with a pull-type clutch release. A pull-type system pulls the release bearing away from the engine to disengage the clutch, while a push-type system presses it toward the engine, so the two cannot be swapped without changing how the release works. OS Giken makes Movement Alteration Kits to bridge that difference on cars like the R34, and Turn 14 lists this kit as required with the R3C clutch for the BNR34.

Why the Kit Is Required

Without the kit, the factory release system on the R34 cannot operate a push-type OS Giken clutch at all. OS Giken designs each Movement Alteration Kit to work with its own clutches only, and notes that using one in an unintended application can cause clutch components to fail. Order it together with the OS Giken R3C Triple Plate Clutch for R34.

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.
