Serpentine Belt Conversion Kits

Everything you need to convert your stock 6 rib serpentine
belt to an 8 or 10 rib! If you are requesting more boost,
causing your 6 rib belt to slip, these kits are for you.
The wider 8 rib belt gives you more belt surface which
can create more boost without the slippage. ATI also offers
a 10 rib kit for those who need extra boost!
Add a reusable Crank Pink Drill Kit #918993 from ATI and pin your crank the right way available for the discounted price of $65 when you purchase any 8 or 10 rib conversion kit.

easily drive a relocated alternator, vacuum pump
or a dry sump pump with your ATI Super Damper.
It’s as easy as specifying the rear pulley at the
time of your order. Available for any damper using
916430M or 916430MK hub. |

kits require a high strength tensioner, bracket and
belt available from Lingenfelter Performance Engineering.
To be used with the Magnuson style supercharger.
[2] - For optional shell assemblies with OD 10 rib serpentine
applications, use the following shells or consult a
technician for more information.

Note: Many blower drive kits supply
a V-belt pulley that bolts to the stock damper with
3 bolts and serves as an adapter to bolt on the 6 bolt
blower pulley. While this system has 6 bolts driving
the blower pulley, the 6 bolt pulley is driven to the
damper with just 3 bolts. Like most blower pulleys,
the ATI true blower dampers have 6 bolt holes on the
Chrysler bolt circle. It is recommended that the adapter
pulley be drilled through 29/64 so that it is sandwiched
between the blower pulley and the ATI damper with all
6 bolts.
