South Bend Dyna Max 12 1/4″ Clutch Kit MU 0090 Rally
$ 97.61
- Description 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. Years 1989-2005, 5 speed & 6 speed non-ETH. When choosing a clutch it is very important to match the appropriate horse power and work load. For example: The MU 0090 Rally and MU 0090 Con O are 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. These two clutch kits are fine 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 the MU 13-1.25 Con O, OFE or FE. This will offer a clutch that will handle heavy towing with vehicles equipped with the higher torque ratings. This clutch only applies to trucks with 5 speed transmissions and early 6 speeds that are not equipped with the HO engine. Do not try and save money when it comes to choosing a clutch. This will only cost you more in the long run. *This clutch is not recommended for heavy towing and will also fit the 99-00.5 NON High Output trucks with NV5600 6-Speed
