  • 16.8 lbs
  • Typically used with 10-1/2" Ram solid hub clutch disc 605-351 and pressure plate 605-401

Notes

NOTE: 

Not For Use w/Stock Clutch Disc, use 10 1/2" Ram Clutch and Pressure Plate, 605-301M or 605-1021 Only.

This flywheel is not compatible with stock type sprung hub clutch discs (5 or 6 springs). A performance type disc with 8 springs must be used. Or aftermarket flywheel bolts like ARP or Mr. Gasket will work with the 5 or 6 spring clutch.

Performance and SFI-approved flywheels must be used with performance clutch discs only. Use of a stock-style clutch disk with a performance flywheel will often result in insufficient operating clearance between the disc hub and flywheel bolts.

To use a mid plate you will need to shim the trowout bearing additionaly away from the transmission approximately the thickness of the mid plate. This is done during the setup of your hydraulic throwout bearing and the fact that the mid plate is there will be nearly un-noticed.

I recently had this flywheel resurfaced for reuse. Upon installation and initially driving the car, I am experiencing a pretty noticeable vibration throughout the rpm range. I pulled everything down and actually ran the engine and checked the runout on the surface and it was .002 at most so I know that the installation is not the problem. This flywheel was on the same engine initially with the same solid hub disk with no issue. Is there a disclaimer about resurfacing causing a balancing issue? I know that this can be common on an iron flywheel but have never thought about a steel piece. More of a curiosity than anything. I would gladly buy another as the value for the price is good. Thanks

We do not recommend resurfacing these lightweight flywheels. The thickness of the friction surface is too thin to allow resurfacing.

Is the 7" cutout in the flywheel the one you can see on the picture or actually in the "back" side of the flywheel toward the engine? I want to use it with a balance plate on a 400 Sbc. Do you have a pic of the other side?

The picture is of the transmission side of the flywheel. The engine side does have a lightening cutout on it but sorry we do not have a picture of it. This flywheel works fine with a balance plate.

Terms and Policy (PDF) 

Note: This flywheel requires very short bolts for mounting, as it is very 'thin' in the center. Use ARP flexplate bolts # 101-2002902.

  • 1-1/8"-10 Spline
  • 2.5 lbs.

Tech Tip:  When installing a new clutch, be sure to follow the manufacturers instructions for correct set-up.  You should also replace the pilot bushing/bearing.

Tech Tip:  To extend the life of your expensive racing clutch you should not use it to load the car on or in your trailer.  The amount of slippage this causes is worse than a night of racing.

(Part #605401)
                        

Ram clutches for stock clutch rule classes give you unmatched performance and durability. These 10.5 inch diameter assemblies utilize a nodular iron pressure ring which provides a durable mating surface for the clutch disc. A 2800 lb. pressure spring provides increased static pressure over stock clutches. 

If your rules require a full facing or sprung hub disc, the RAM 300 Series organic racing disc provides the best holding power of any organic disc available and adds only about 2 pounds to the total weight of the set.

All Ram street stock clutches are completely rebuildable by the factory.
