Does the Super Lock LSD for DC5 fit the 2005-2006 RSX Type-S?

Turn 14 lists the Super Lock LSD for DC5 cars, part number HA081-HA, for production from July 2001 to September 2004. The facelifted 2005-2006 RSX Type-S falls outside that range, so confirm fitment with Bulletproof Automotive before ordering for a later car.

What does 1.1-way mean on the DC5?

A 1.1-way LSD locks strongly under acceleration and only lightly on deceleration. OS Giken uses it on front-drive cars so turn-in and lift-off feel stay close to an open differential, while drive out of the corner gains the full locking effect of the clutch plates.

Will it cause torque steer?

Any limited-slip differential in a front-drive car adds some steering feedback under hard acceleration, because both front tires are now driving. The low preload and progressive lock of the Super Lock keep that effect moderate, and most drivers find the extra traction worth the added feedback.

Is it worth it on a street-only RSX?

Less so. The main gains come on corner exit at the limit of grip, at autocross or on track. A street RSX driven gently will see little difference. For a car that is driven hard on track, it is one of the most effective changes available.

Can it be rebuilt and retuned?

Yes. OS Giken rebuilds and retunes Super Lock units in-house, changing initial torque with cone springs, lock timing with pressure ring springs and ramp angle with the pressure ring and iron cross, so the unit can follow the car as it develops.

Description

OS Giken Super Lock LSD for DC5 Acura RSX Type-S and Honda Integra Type R

OS Giken’s Super Lock LSD for DC5 Acura RSX Type-S and Honda Integra Type R gives the K20A front-driver a clutch-type differential, which is the single biggest change for a DC5 that sees a track. The US RSX Type-S left the factory with an open differential, so under power out of a tight corner it spins its inside front tire and the traction light does the rest. OS Giken’s patented pressure ring locks progressively, and in the SPEC-S tune it runs 1.1-way on front-drive cars, so turn-in stays close to stock. It suits an RSX or Integra used at autocross and track days.

Design and Performance

OS Giken carries the friction plates on splines through the side gears, fitting up to twice the plates of competing designs. More plate area lets the unit run a gentle preload for daily driving while still reaching full lock under power. The case is machined from a single billet and all parts are raw-forged or chemically heat treated.

Features

Clutch-type front differential for the K20A six-speed
1.1-way action on front-drive cars in OS Giken SPEC-S tune
Patented pressure ring for smooth, progressive lock
Up to twice the friction plates of rival designs
Billet case and raw-forged gears
Retunable for initial torque, lock timing and ramp angle

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.
