The 0090 South Bend Dyna Max Clutch is an excellent choice when replacing the stock clutch on a stock truck without performance modifications.
This Dyna Max kit features an organic friction material comprised of 808 composite, resulting in a significantly reduced operating temperature which gives this kit ultra-smooth engagement & extended life. This kit will hold up to 350 horsepower & 700 ft. lbs. of torque.
Other than the flywheel, this is a complete clutch replacement kit and comes with everything you need to do the job including Throw Out Bearing, Stock Needle Pilot Bearing and alignment tool. *88-93 Getrag trans must re-use stock crank bolts*
When choosing a clutch it is very important to match the appropriate horse power and work load. For example: The 0090 is capable of handling the horse power and torque ratings provided in our listings, but if the truck is used for heavy hauling when coupled with torque ratings exceeding 600 ft. lbs. damage to the clutch disc WILL occur. The cause and effect is the 12 1/4" disk does not provide enough dampened area to absorb the added torque of the Cummins along with heavy hauling. The 0090 is great for light towing and performance. If you are going to be towing in excess of 8,000 lbs. while exceeding 600 ft. lbs. of torque you must go with one of the 13 inch clutches: 13125 OFEK, 13125 FEK. This will offer a clutch that will handle heavy towing with vehicles equipped with the higher torque ratings. The 0090 only applies to trucks with 5 speed transmissions and early 6 speeds that are not equipped with the HO engine. If a 12 1/4" clutch is purchased and gets destroyed at the dampened portion of the disc, warranty will not be granted.
NOTE: It's very important to Break-In your clutch with 500 miles of stop and go driving before you pull a load. Your clutch will last longer if you avoid down-shifting whenever possible. Down-shifting flexes the pressure plate, causing uneven wear. Just remember, Use your breaks instead--they're are alot less expensive to replace!
Warranty: 1 year, 12,000 miles, whichever comes first, manufacturer defects only.
