Do I need an accessory kit for the EXEDY Hyper Single Clutch on the Solstice?

Yes. EXEDY sells a Hyper Series Accessory Kit separately for every Hyper Series clutch, this Hyper Single Clutch included. Confirm the kit EXEDY lists for the Solstice before ordering, so the parts it specifies for a full installation are on hand when the transmission comes out.

How much torque can this Hyper Single Clutch hold?

EXEDY does not publish a torque figure for this GH03SD unit; across the Hyper Single range it states roughly twice the holding torque of the factory clutch. The Hyper Single suits a moderately modified Solstice; builds well beyond that should look at an EXEDY Hyper Twin.

Is this the clutch only?

Turn 14 lists this part as a Hyper Single clutch with a sprung center disc, without a full parts breakdown. Check the contents with us before ordering if a flywheel is needed, and order the Hyper Series Accessory Kit separately for the bearings EXEDY specifies.

Is the Hyper Single a good street clutch for the Solstice?

It can be for a modified car. EXEDY aims the Hyper Single at moderately tuned cars that do not need multi-plate capacity, and the sprung hub softens engagement, but the cerametallic pucks bite harder than an organic disc. For a mostly stock Solstice, an EXEDY Stage 1 organic clutch is the gentler choice.

Why choose a single disc over a twin plate?

EXEDY builds the Hyper Single disc smaller and thinner than the factory disc, which lowers rotating inertia for quicker shifts and less wear on the synchros. A twin plate holds more torque but costs more and engages more sharply, so the single disc is the better fit until the Solstice makes power the single cannot hold.

Description

EXEDY Hyper Single Clutch for Pontiac Solstice

EXEDY’s Hyper Single Clutch for Pontiac Solstice is the push-type sprung-disc single EXEDY lists for the 2.4 liter Solstice roadster of 2006 to 2009. Turbocharged Ecotec swaps and tuned Kappa roadsters outgrow the stock clutch, and a cerametallic Hyper Single gives them more holding power while keeping a sprung hub for street driving.

Design and Performance

EXEDY forges the cover from aluminum and anodizes it purple, a stiffer part than a pressed steel cover, which lets EXEDY use a higher lever ratio without a heavy pedal and avoids the clamp-load deflection of stamped covers. The pressure plate carries turbine-like vanes that move air through the clutch to keep it cooler, and EXEDY rates the Hyper Single at about twice the holding torque of the factory clutch.

Features

Single disc with six-puck cerametallic facing and a sprung center hub (SD)
Purple anodized forged aluminum cover, stiffer than a pressed steel cover
Pressure plate with cooling vanes for airflow under hard use
Cover type Push type

Applications

Pontiac Solstice: 2006-2009 | 2.4L I4

Notes

The EXEDY Hyper Series Accessory Kit is required for installation and is sold separately

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.
