Alignment of the cover plate and floater plate are critical for proper operation of the RAM Street Dual. The pressure plate straps and floater plate straps must be staggered as in illustration A below.

About your Street Dual drive stands

Your new RAM Street Dual is assembled with 3 composite drive stands that significantly reduce floater plate rattle. These stands are designed for use in street car applications. If you plan to race your vehicle frequently, drive it excessively hard, or if the car IS a race car, these stands need to be changed over to the steel stands. Three of the steel stands are enclosed with this clutch system.

Before installation

Test fit both discs on the input shaft of the transmission. Make sure they slide freely on the splines.

If you are using an aftermarket bellhousing, it MUST be dial indicated to the engine before installing the clutch. These bellhousings typically are not centered and can cause release issues if not addressed.

Clutch installation

Remove the pressure plate attachment nuts from the flywheel stand bolts (3/8” 12-point nuts). Notice the proper orientation as noted above. Be sure the unit is installed this way. Lift the cover from the flywheel. The top disc is a sprung hub configuration. After removing the sprung hub disc you will see the floater plate.

The floater plate drives off of the six pressure plate stands and is tethered to the flywheel with three straps which are bolted in position. Notice how the floater plate moves freely up and down around the drive stands. This is how the floater should fit when installing the unit in the car. If the floater plate is bound to or hung up on the drive stands during installation the clutch will not release properly. Note: the drive stands each have shims on top of them. Be sure they are in place when the unit is installed.

Remove the three 5/16-18 capscrews and lift the floater plate out of the assembly. Be sure to retain the 3 – 5/16 washers located under the straps. The solid hub bottom disc can now be removed.

Install the flywheel loctite or similar thread locker on the flywheel bolts. Torque the flywheel bolts to 75-85 ft/lbs.

Slip the top clutch disc (sprung hub disc) onto the clutch alignment shaft followed by the floater plate and bottom clutch disc (solid hub). Be sure the floater plate side that has the machined outer lip is facing the transmission (i.e. the completely flat side towards the flywheel).

Slide the clutch alignment tool into the pilot bushing while positioning the floater plate over the drive lugs. The three retaining straps should line up with the three 5/16-18 holes on the flywheel surface.

Install the three 5/16-18 capscrews through the strap and washer and into the flywheel (note: the straps should line up without any repositioning). Use a threadlocker on the capscrews.

At this point make sure the floater plate moves freely up and down on the drive stands and that the retaining straps slide freely on each mounting bolt. The floater plate must move freely or the clutch will not disengage properly.

Place the pressure plate over the stand bolts and torque the cover nuts to 30 ft/lbs tightening them in a star pattern so that the diaphragm is pulled down evenly. Be sure the cover drive straps are offset from the floater straps and that each stand has its shims between the cover and the stand.

The bellhousing and transmission can now be reinstalled. Be very careful not the let the transmission hang on the clutch disc spline during reassembly as this may bend the clutch disc carrier, which will cause release problems.

Adjustment

Mechanical & Cable linkages

Adjust your pivot ball to achieve a forward attitude (drivers side pivot) or rearward (pass. Side pivot) on the clutch fork when the bearing is just touching the fingers. Set the release low to the floor, maximum freeplay. If this is not comfortable then use a pedal stop to avoid excessive release.

LS1 hydraulic applications

RAM recommends using an adjustable master cylinder with this clutch assembly so you can limit the clutch travel and avoid shifting problems. Set the clutch pedal for minimum release, that is keep the pedal as low to the floor as possible.

Other modifications

If using a safety bellhousing (and we strongly recommend you do), be sure to follow the manufacturers instructions for proper bellhousing alignment.

LS1 F-body cars need to have the ‘drill mod’ performed. The factory restriction can slow engagement of the clutch and even cause a low end slip in extreme situations. An excellent step by step guide is located at www.installuniversity.com/ in the ‘install documents’ section.
