ProGrip™ Clutches and Flywheels were born out of the general confusion and frustration most people feel when choosing the right components to handle their power and performance needs. We have taken the frustration out of the process by offering clear power ratings, reasonable prices and a sales staff that actually has the answers to your questions!

GM Clutch Kits

Whatever your clutch and flywheel needs, choose ProGrip™ to cruise or to hook and cook!
The ProGrip™ Difference
All clutches are not created equal!  Every ProGrip™ component is built to our specifications based on years of powertrain experience.  These are the clutches we would put in our own cars.  Whenever possible, our clutch components are made in the USA.
Kit Contents
Every ProGrip™ kit includes the proper pilot tool, a high quality pilot bearing and, when applicable, a new US Made release (throw-out) bearing. 
Price
Beware of the HYPE!  Only a few companies actually manufacture clutches.  Often you are paying lots of extra money for the a color or for fancy names and gimmicky pressure plates.  ProGrip™ clutches are a straightforward way to choose a great clutch for a reasonable price without all the hype.

A few quick things to consider:
Rating Standards Clutches are rated with torque limitations rather than horsepower.  If you do not know how much torque you have make your choice based on rear wheel horsepower as a loose equivalency.   All torque ratings on these clutches are figured with a 15% safety margin for those who wish to push their luck.
The Right Clutch for the Job Choose a clutch with no more than 20% greater torque rating than your engine produces.  Too much clutch can be just as bad as too little.
Choosing a Pressure Plate Because of advanced friction materials it is possible to handle loads of power with a very comfortable pressure plate.  Try to stay with a standard clamp load plate if possible unless you are in love with higher pedal effort.
Choosing and Buying a ProGrip™ Clutch
is as Easy as 1-2-3!
1. Find your application: We have clutches for almost every domestic V8 powered vehicle built since 1955! Remember, clutches are engine, flywheel and transmission input-spline specific and are not specific to car model. Typically, small block applications call for 10.5” clutches, while most big blocks are 11”. This is not a hard and fast rule and varies by year and engine. If you can’t find your application or don’t know what you need, call and let us help.
2. Choose your pressure plate: Based on size, clamp load and ease of actuation. All standard clamp load ProGrip™ pressure plates feel amazingly close to a stock modern clutch. Think new Mustang, Corvette or Challenger. High torque pressure plates add a little more leg effort and increase torque ratings. Generally speaking, it is best to choose a Standard Clamp Load pressure plate, with a disc that suits your power needs. Step up to high clamp load if you can’t get to your power rating with a standard plate.  ProTwin™ pressure plates are very light on the leg and afford the most extreme performance with the least pedal effort.
3. Choose your clutch material: Based on the descriptions below and your power needs. All of these discs are fully streetable, though some are more forgiving than others. Our staff will be happy to discuss these options if you would prefer to call.

The mighty ProTwin™ available for all Domestic V8 Applications, is the most technologically advanced dual-disc system available!

“Well I went for a couple of drives, everything seems excellent, the clutch is really good, no chattering at all, very easy to drive.  The trans shifts very nice for being brand new, I am already loving the ,64 overdrive… Day two was excellent, I have almost 200 miles on it already.....can't wait to try it at the track!!”

600Extreme, ProGrip ProTwin Clutch

ProGrip ProTwin Clutch ProTwin™ Clutches Feature:

► Light pedal effort, lighter than most stock clutches
► Insane holding power: Up to 1025ft-lbs
► Cryo hardened pressure plate and billet floater plate
► Progressive Engagement – no on/off switch feel
► Low Price – Hundreds of dollars less than competitors
► Choice of
Organix™ or Ceramix™ discs
► Choice of race balanced Billet Steel or
     Billet Aluminum Flywheel
► No shims necessary – just bolt and go!
► All hardware, pilot bearing and alignment tool included,
► The lowest price for a street/strip twin in the marketplace!

Clutch Materials:
ProGrip Organix™ Discs are a step above a stock disc, using greater grip and a fully sprung hub to return energy gradually to the system and a Marcel cushion spring, making them a smooth choice for street, strip and circle track applications. Use Organix™ from stock to about 500ft-lb applications.
ProGrip™ Full Circle Kevlar discs are very smooth, with tons of grip and great heat dissipation. They also last about 3-5 times longer than stock organic discs and won’t chatter like some of their dual friction cousins. Great for stock to 650ft-lb street or strip applications where superior durability is a concern. ProGrip™ Full Circle Kevlar discs are fully cushions and feature a shock reduction sprung hub.
ProGrip Organix™ /Ceramix™ Dual Friction discs are smooth and compare favorably to Centerforce dual friction material at a lower cost. This is a slightly less streetable option compared to the Full Circle Kevlar, and offers low chatter characteristics with lots of grip and both a sprung rebound hub and a flexible Marcel cushion. Great for 450 to 650ft-lb applications, a smooth way to take advantage of the fantastic characteristics of Ceramix™ without the harsh uptake of a no-cushion hub.
ProGrip Ceramix™ Extreme discs are The Big Kahuna of single disc clutch applications; Ceramix™ discs have almost twice the grip of organic material. While a sprung hub gives them excellent rebound control, they can chatter some when cold. A very affordable alternative to big dollar twin disc clutches, ProGrip Ceramix™ is the best high power bang for your buck. Excellent for 500 to 850ft-lb applications.

Disc Terms:
Full Circle Friction material covers the entire face of the clutch.  This provides smoother engagement and eliminates chatter.
Button/Puck Style Small sections of friction material is bonded or riveted to the clutch substrate.  Generally associated with very high friction materials.
Marcel/Cushion A flat spring sandwiched between the layers of friction material to provide smooth engagement.
Rebound/Sprung Hub Provides shock reduction to protect transmission components.  A sprung hub is loaded with energy on engagement and gradually returns it to the system.  All single disc ProGrip™ clutches feature a sprung hub.
Captured Spring While many clutches use a small split in the hub material to house the rebound springs, most ProGrip™ clutches use a stamped plate to fully capture the springs and hold them in place.  This is a safer style of hub and allows the springs to load in a linear fashion without becoming inch-worm shaped.  This is the most efficient way to store and return shock load to the system.
Dual Sprung Hub ProGrip™ discs feature dual springs in the clutch hubs to soak up more energy without using oversized diameter springs.  This allows better clearance to the flywheel bolts for the life of the clutch.
Solid Hub Some clutches do not use a cushion due to the inflexible nature of the material.  Ceramix™ discs do not have a cushion, however they still feature a rebound hub to smooth engagement and protect your transmission.  ProTwin™ discs have no springs in their solid hubs and use progressive uptake to soak up shock load instead.
