Shop SPEC 944T PUSH TYPE

SPEC STAGE 1 thru 4 CLUTCH KITS 944T "951" ** NEW PUSH TYPE **

This series of SPEC Clutch Kits Eliminates the Clutch Fork and Clutch Slave Cylinder.



In 2014 Lindsey Racing introduced the SPEC MINI TWIN clutch for the 944 Turbo. We asked SPEC to develop this kit for a number of reasons and it's been performing as advertised. Offering the customer an extremely light weight twin disc clutch with incredible holding capability and a super fast shifting experience.

One of the unique features of that clutch kit is that it eliminates the clutch fork, clutch slave cylinder and some of the hydraulic components. All or which can be either a failure point or a lack of availability issue. It utilizes a hydraulic clutch release bearing similar to what is the norm in today's modern automobiles. The mechanical clutch fork is fast becoming a thing of the past.

We thought how nice it would be to be able to utilize this type of clutch release bearing on your typical existing 944 Turbo standard type single disc clutch kit. However, that would not be possible with current clutches because the fork system "PULLS" on the pressure plate diaphragm where it would be necessary to "PUSH" on the diaphragm. Unfortunately everything worked backwards or opposite of what it needed to be for that to happen.

In 2015, Lindsey Racing approached SPEC about developing a new clutch kit for the 944 Turbo that will eliminate the need for the problematic and difficult to obtain clutch fork and unitize the "PUSH" components in the kit for all it's benefits.

SPEC did just as we asked and here is the result of that development. A brand new never done before completely unique "PUSH" type clutch kit for the 944 Turbo. This is going to change everything.



This new kit increases the holding capability of each stage of kit because of the additional clamp load on the pressure plate design. In most kits, about 70 ft lbs over the same stage disc in the standard pull type kit. In addition, they are introducing a brand new Stage 1 disc material that not only engages smoother, but lasts longer then before. So even a Stage 1 clutch kit with a smooth action similar to a stock clutch is capable of holding 430 ft lbs or torque. Customers with up to that HP level how have the kit that will do what they have been wanting one to do for years. Hold a lot of power, yet engage like a stock clutch. Something that before now, was only an unfulfilled request.



The kit has an all new Aluminum Pressure Plate cover designed and built just for this new kit. It's also anodized blue for corrosion protection. This clutch and flywheel combination saves 8 (+/- depending on the clutch stage/disc) pounds of rotating mass over a stock clutch.



It also required an all new Billet Steel Flywheel to accommodate the new Pressure Plate. This flywheel looks very similar to the SPEC SP-44S we had them develop a few years back for the standard pull type (stock) 944 Turbo clutch kits. Yet because of the change in direction, the depth dimensions had to change.

The only thing not new on this kit is the clutch discs. They use the same SPD-29X part number discs as the pull type kits. So this means you can get a Stage 1, 2, 3, 3 Hybrid, 3 Full Metallic, 4 and 5 kit to suit your application. Feel free to consult us for picking the best kit for your needs.

Stage 1



Features an integrally molded carbon kevlar-based, high performance organic lining that offers smooth engagement and excellent life. This lining has an integrally bonded steel backing for strength under high clamp loads and temperatures. The hub is double sprung with spring cover relieves for flexibility and heat treated components for strength and durability. Best for street and many track/off-road applications.

Stage 2



Features segmented or full faced pure Kevlar disc with steel backing. This lining features excellent drivability like the stage 1, but offers slightly longer life and higher torque capacity. The hub is double sprung with spring cover relieves for flexibility and heat treated components for strength and durability. Best for street, drag, pulling and autocross.

Stage 3



Features a carbon semi-metallic 6 puck (optional 4 or 3 puck)sprung hub disc that has been the leading puck clutch in drivability, life and torque capacity. This unit is designed for street and race cars that require an aggressive but streetable engagement and high torque capacity. The hub is double sprung with spring cover relieves for flexibility and heat treated components for strength and durability. Also available in 3 puck configuration. Great for street, drag, road racing, pulling, rally and drift.

Stage 3 Hybrid



Features a multi-friction disc in a full faced configuration with carbon semi-metallic on one side and Kevlar on the other. Bridging the gap between stage 2 and stage 3, the Hybrid or also called 2+ offers drivability and engagement quality characteristic of the stage 2, but with a 15-20% higher torque capacity. The hub is double sprung with spring cover relieves for flexibility and heat treated components for strength and durability. Great for street, drag, autocross, road racing, pulling, rally and drift.

Stage 3 Full Metallic



The flagship stage single disc for a high powered street or race car that requires a manageable and friendly engagement, the Full Metallic or also called stage 3+ features a carbon semi-metallic full faced material that offers unparalleled life, friction co-efficient and drivability characteristics in one single package. The hub is double sprung with spring cover relieves for flexibility and heat treated components for strength and durability. Great for street, drag, drift, autocross, road racing, pulling, rally and drift.

Stage 4



This unit is a solid hub version of the stage 3. The hub is solid 8-rivet design and the assembly is heat treated for strength and durability. It is available with a 6 puck or optional 4 or 3 puck configuration. Use the 3 puck for the lightest option or the 6 puck for the smoothest engagement. The 4 puck is a good compromise for both. Street drivable in 6 puck configuration, but not street friendly due to the rigid hub. Best for drag racing, road racing, pulling, rally and drift.

CLUTCH STAGE TORQUE @ CRANKSHAFT
STAGE I 430 ft lbs
STAGE II 485 ft lbs
STAGE III HYBRID 545 ft lbs
STAGE III 6 & 4 PUCK 580 ft lbs
STAGE III FULL METALLIC 671 ft lbs
STAGE IV 6 & 4 PUCK 580 ft lbs
STAGE V (DRAG RACE) 620 ft lbs

INTERNATIONAL ORDERING



TO OUR INTERNATIONAL CUSTOMERS:


In the past, we have used a separate order form for placing International orders. We have quit using that process and are requiring all customer to use the shopping cart system built into the web site and it's check out process.

If you simply want a quotation and are not ready to place an order, then cut and paste the contents of your shopping basket, take a screen shot of the basket, or make a list of items and send us a email requesting a quotation with shipping.

If you need shipping prices before you make your final decision to purchase, then you should request that quotation by email and not use the shopping cart checkout process because you will be paying for the parts at that time.

Since our shopping cart and shipping estimator will "NOT" correctly calculate shipping charges on International Orders, we have it set-up to where the shipping will be Zero Dollars ($0.00) when checking out. When the shopping carts address process learns you are not in the United States by selecting your particular country, that's when it switches to equal Zero. That does NOT mean shipping is free.

Upon completion of the check out process, you will have paid for your parts but NOT the shipping on those parts.

Once we look over your parts ordered and calculate shipping weights and box sizes, we will send you an E-Mail with at least one shipping option and maybe several. We utilize UPS, DHL and the United States Postal Service (USPS) to deliver your parts.

Once you pick a shipping carrier and agree to the quotation by returning the E-Mail, we will be sending a PayPal money request for the amount of the shipping to be collected. If the parts are expected to be shipping out quickly, then you may receive that email quickly. If the parts are going to need to be built or something is on back order from the list of parts, we may hold off sending that E-Mail until we have the shipment ready to go. It can vary from order to order as to how we do that. If you think you should be hearing from us quickly, but you don't, feel free to contact us.

If you have special shipping needs or requirements, during the checkout you will see a SPECIAL ORDER INSTRUCTIONS window. Enter that special information there.

A good bit of our business is International and we have been taking care of those valued customers since 1999.
