Pontiac GTO: Transmission/Drivetrain

RAM-1550

Cast flywheels are not explosion-proof, and can be dangerous when used in high-performance applications at higher rpms. RAM billet steel flywheels are recommended as replacements for factory-cast flywheels in high-performance and racing vehicles. They´re better for launching heavier drag race cars and provide better drivability in street vehicles. RAM billet steel flywheels are CNC-machined from certified materials, and friction surfaces are Blanchard-ground parallel to the crankshaft mounting flange, for minimum runout and optimum clutch engagement. These flywheels are SFI-approved. 26lbs

 

Powergrip HD Clutch sets

Powergrip HD sets are the ultimate for extreme street/strip performance.  Using our proprietary 900 series friction material in conjunction with increased clamp load pressure plates, you get maximum holding power for track or street, with only minimal reduction in driveability.  This is the set for big power street cars!  Some chatter will occur on takeoff.  Use only with RAM billet steel or factory nodular iron (explosion resistant) flywheels.

Street Dual Clutch Systems

RAM clutches proudly introduces our dual disc clutch system for late and early model muscle cars.  The assembly consists of an aluminum flywheel, easy pedal effort diaphragm pressure plate, 300 series friction material, and a special floater plate and retainer system that virtually eliminates floater plate rattle.  Holding capacity for this clutch is in excess of 1000 hp, yet the engagement is silky smooth thanks to the 300 series friction material.  Now you do not have to deal with on/off switch clutches for your high horsepower street machine!  The system works with the factory release mechanisms.

 

RAM-2550

If you´re building an all-out competition car, you need a lightweight flywheel that will allow the engine to rev quicker and not eat up a lot of power. RAM billet aluminum flywheels greatly reduce rotating weight, to permit quicker revving and higher power output, but still retain enough mass to resist heat distortion that could adversely affect clutch performance. These flywheels are CNC-machined from certified materials and have a rugged steel friction-surface insert. The insert is Blanchard-ground parallel to the crankshaft flange after installation, to minimize runout and provide the optimum clutch-mating surface. These flywheels are SFI-approved. 18lbs      

The factory driveshaft in the GTO is the weakest part of the entire driveline. It´s a two piece design that is only 2 inches in diameter and uses rubber mounts instead of u-joints. Not only do the rubber mounts contribute to wheelhop, they are notorious for failing on even slightly modified 6 speed cars. Our heavy duty driveshafts are a one-piece design that use forged 1350 series u-joints. Each driveshaft comes with a cryogenically frozen front yoke and a custom machined 300M billet pinion yoke adaptor (shown below). NOTE: Due to the physical size of this driveshaft, the factory exhaust may require some modification. Most aftermarket exhausts tested do not have clearance issues. Steel driveshafts not recommended for 6 speed cars. Driveshaft needs additional spacer if using Harrop Differential cover.
