McLeod RST Street Twin clutch

Intended for the high horsepower street/strip fan, the McLeod RXT Street twin clutch kit is an economically priced twin disc clutch kit that does not require a dedicated flywheel( you use your existing flywheel) in most applications. Able to handle 1000hp, this clutch can handle almost any horse-power you can throw at it and still remain street-able. Metallic lined clutch discs will provide smooth engagement with a soft pedal effort to make this clutch kit ideal for the street performance enthusiast.

Kit Includes: Pressure Plate, two ceramic friction discs, floater plate, adapter ring and pilot tool.

Fits GM engines and 1-1/8″ 26 spline input shaft.

This McLeod steel flywheel is perfect for fitting an LS T56, like the Tremec T56 Magnum, to a small block Chevy engine with a 2 piece rear main seal (1955-1985) and all big block Chevy engines.

McLeod steel flywheels are perfect for street applications where easy stop light acceleration is desired. They are also recommended for rock crawlers and off road driving. Our steel flywheels are CNC machined from billet alloy steel. They have 1045 hardened steel ring gears.

For externally balanced engines, add McLeod counterweight kit 560222.

• • Flywheel Steel 30#
  • SBC 305-350″ 1955-1985 neutral Balance
  • 2 Piece Crank Seal
  • 168 Tooth – will require a starter change if you currently have a 153 tooth flywheel

McLeod StreetPro clutch kits are great for replacing your worn factory clutch or for swapping in a manual transmission.

This clutch is single disc with organic friction material.  Fits small block Chevy engines (as well as others) and transmissions with a 1-1/8″ 26 spine input shaft.  11″ diameter, requires 168 tooth flywheel.

For higher horsepower applications, the Force 10.5 dual disc is the natural choice. Based on the design of the original RAM Street Dual, Force 10.5 is more street friendly by using a three strap system  to locate the floater plate. This eliminates floater plate ‘rattle’ that is common on stand driven dual disc clutches. A high clamp load pressure plate assures plenty of holding power without excessive pedal pressure. Steel backed 300 series facing mean smooth engagement on takeoff and insure long service life. For higher torque capacities, the Force 10.5N features the proven RAM 900 series metallic facings. Force 10.5 dual disc systems handle bigger torque loads and are a bit heavier than their smaller cousins. This higher inertia translates into better low speed drivability in heavier vehicles, or in large camshaft profile applications. If you are bolting on a larger blower or turbo system, Force 10.5 may be the best choice for you.

RAM’s storied history of building single and dual disc clutches for real race cars led to the design and production of the RAM Concept 10.5 dual disc clutch system. The Force 10.5 features an integral steel or aluminum flywheel, properly balanced for your engine out of the box, as the basis for the clutch system.  We then add the features listed below to surpass other clutch market designs, such as:

• Size – the larger the diameter the more the holding power the clutch system will have. The 10.5 pressure plate has 2400 pounds of clamp pressure, where competitor’s 9.5 assemblies typically have 1800 pounds of clamping force.  The larger clutch diameter will also further enhance heat dissipation over the smaller units.  Stock pedal effort is maintained with the Force 10.5 unit.
• Precision machined billet flywheel provides a stable mounting platform.  Each unit is set up on the flywheel before shipping to insure proper release once the clutch is installed.  A specification card is provided with each unit to aid you in setting up the clutch properly in the car.
• Precision balance on the flywheel insures proper balance and vibration free driving.  Match balancing available by special order.
• Strap driven floater plate system assures quiet, no-rattle operation.
• Utilization of a sprung hub top disc to ease stress on the driveline during initial engagement.  Dual solid hub designs are aggressive and more susceptible to gear noise in the transmission.
• The Force 10.5 is available for most any engine platform and in most cases, are a direct bolt in replacement for the factory clutch.
• Available with 300 Series organic friction material for a super-smooth engagement on the street and holding power up to 750 HP.  A 900 Series metallic version is available for extreme duty/competition and is capable of holding in excess of 1000 horsepower.  Like any clutch system, the horsepower capacity is dependent on load factors.

STREET AND COMPETITION PERFORMANCE TO 650 HORSEPOWER

HD street/strip clutch for many transmissions behind a small or big block Chevy engine.

Tremec T56 Magnum

Tremec T56 from ’98-’02 F-Body

​POWERGRIP HD is a true “strip/street” competition clutch system that can handle the rigors of weekend racing and spirited street driving. This system has the same components as standard POWERGRIP above with the exception that the disc friction surfaces are both sintered metallic. Sintered metallic provides a degree of slippage on vehicle launch to prevent the violent and uncontrollable engagement characteristics of paddle type metallic discs. This firm consistent engagement is easy to control. Some chatter is likely on engagement with rear gearing less than 3.73 in street applications. Each set includes the pressure plate, clutch disc, release bearing, and alignment tool unless otherwise noted. Use Powergrip HD for power levels to 650 horsepower, or lower powered vehicles that see frequent track duty.
