Diaphragm type twin-disc clutch assemblies are vested with either “stands” or “straps” that secure the floater plate to the flywheel in relation to the sprung top clutch disc and the solid-hub bottom disc.

The issue with the stand arrangement is noise. The floater has a millimeter or two to move about on its (six) stands as the car is at idle with the clutch pedal depressed or when it is released to move the vehicle. Though not a concern with a racing application, it becomes an itch that can’t be scratched in a street-driven LS1, 2, 3, 6 or 7 or a Ford Modular 4.6L or 5.4L.

The RAM Force 10.5 incorporates an upper or “curved” strap that is the load-bearing strap for the pressure ring. The lower straight strap is the load-bearing strap for the floater (see accompanying close-up image). Both upper and lower straps are made of spring steel. This companion device totally eliminates the noise associated with stands.

Force 10.5 units use Ram’s 300-series steel-backed friction discs that feature an eight-spring hub assembly with urethane encapsulated springs for added durability as well as a marcel spring (a thin, wavy device) that helps eliminate the “go-or-no-go” tendency that accompanies most dual-disc clutches. A billet aluminum flywheel rounds out a package that weighs an average of 45 pounds.

All assemblies are 10.5-inch in diameter and are built to factory height dimensions. Original equipment hydraulic clutch systems are static and have no manual adjustment so the clutch and flywheel package must be the same height as the stock equipment. Installed heights are identical to OEM dimensions–no modifications necessary.

All 300-series discs are made from organic material for smooth engagement and are more than sufficient to deal with 900 horsepower. The springs in the disc are urethane-coated and have four times the compression rate as compared to uncoated springs. Clamping force is 2,400 pounds. Both sides of the steel floater plate are surface-ground to the same tolerance. (NOTE: The RAM 900-series discs are made from sintered metal and can hold up to 1,400 horsepower.)

A key feature of RAM aluminum flywheels is the steel insert that has enough mass to draw heat away from the clutch without distortion. RAM uses a 0.250-inch thick inset that is riveted in before the flywheel is surface ground to assure a parallel friction surface with no run-out, and enough material to adequately siphon off the heat while maintaining flatness over time. All RAM billet flywheels are SFI certified.

Identification for these quiet, twin-disc packages are as follows: All LS applications are 1 1/8-26 (PN 80-2100). There are four call-outs for the Ford Modular: 4.6 8-bolt 1 1/16-10 (PN 80-2200), 4.6 8-bolt 1 1/8-26 (PN 80-2220), 4.6 6-bolt 1 1/16-10 (PN 80-2260), and 4.6 6-bolt 1 1/8-26 (PN 80-2265). Price point is approximately $1,400. Units are in stock and ready to ship.

FastMetalRacing.com presents racing's first ever Easy View sparkplug indexing socket. Built with the racer in mind, their goal is to help the utilize their time and get all they can get out of their motor's performance.

By indexing the sparkplugs, you ensure proper combustion evenly across the piston's top utilizing the entire area of the pistons surface. This has been proven to provide a three to seven percent power increase and that represents free horsepower. Also by indexing your sparkplugs, you can keep the piston's dome from contacting the spark plug's ground strap and possibly closing the sparkplugs gap.

Wonder why the slot? When you mark your sparkplug's index mark to see its placement, it enables you to avoid re-adjusting the socket in order to locate where you are tightening the sparkplug. One advantage is the ability to feel or see the slot in tight, hard-to-see areas with your finger.

Jiffy-tite, an innovator of quick-connect self-sealing fluid fittings, has introduced EPDM seals to their range of acclaimed fittings. EPDM, a type of synthetic rubber, is compatible with brake fluid— making these new quick-connect fittings ideal for all hydraulic clutch systems, and especially useful for stock car racers. EPDM is also compatible with nitromethane, and these new connectors, all rated for 200 PSI, are now available in a variety of configurations for nitromethane fuel systems.

Fuel systems with AN aluminum threaded fittings, particularly those on racecars that are constantly being threaded and unthreaded, often leak eventually. Jiffy-tite eliminates threaded fittings and replaces them with quick-connect self-sealing fittings. The result, they insist, is no cross-threading, no over-tightening, no forgetting to tighten, no leaks, no plumbing issues and no unsightly wrench marks or scratches on the fittings. And they are connected and disconnected in seconds.

These unique connectors have a further advantage: they eliminate the number of excess fittings in most plumbing systems—the process is streamlined. Compared to conventional AN aluminum fittings, which extend to hundreds of part numbers for nipples and unions and reducers, Jiffy-tite’s solution is simple: one plug and one socket. Using this technique a -6 AN line, for example, can be reduced to a -3 AN line with just two fittings.

An Original Equipment Manufacturer to GM, Chrysler, and other auto makers as well as the U.S. military, Jiffy-tite produces fittings with two other popular seals: Viton Fluorocarbon and Nitrile Buna-N seals. The Viton Fluorocarbon seals are suitable for water; gasoline, leaded and unleaded; racing fuels; diesel; bio-diesel; and most oils, including transmission applications. The Nitrile Buna-N seals are compatible with most alcohol fuels.

Created for high-horsepower engines and now available on 24-Hr QuickShip program

Trend Performance is introducing a new series of bronze-insert one-piece pushrods. They are prepared especially for Pro Stock teams, 800 CID Mountain Motor racers, Top Sportsman teams, and large-displacement nitrous engine builders. Further, they are particularly proficient in resolving lubrication troubles around the rocker balls. In addition, BZ pushrods are now available on Trend’s 24-hour QuickShip program.
   
Created from 4130 chrome-molybdenum thick-wall tubes, pre-formed and centerless-ground with a high-load bearing bronze insert, these shelf-stock items are fully heat-treated and available in diameters of 7/16 x .165-inch wall or 1/2 x .200-inch wall or 9/16 x .187-inch wall. On the lifter end they are manufactured with conventional ball-end diameters of 5/16 or 3/8 inch. On the top end, the bronze insert is press-fitted and machined with a .140-inch radius cup—designed to accept the popular 9/32-inch rocker adjuster ball.
   
This new BZ Series is case hardened to Rockwell Rc60 for extra strength and rigidity and made available in straight form, full single taper, or double taper (tapered from the center to the each end)
   
To lubricate the upper cup and rocker ball, a thin oil passageway runs through the center of the pushrod allowing pressurized oil to travel from the lifter bore to the rocker.
   
The heat treating process for the BZ Series is a one-step carbo-nitriding process, administered in an atmospheric furnace containing a combination of ammonia and natural gas. Carbon is induced into the surface of the pushrod from the natural gas, nitride from the ammonia.
