C7 LT4 10-Rib Conversion

$900.00

Quantity

This 10-rib conversion has been designed, programmed, and machined entirely in house (with the exception of the OEM GM parts included). This allows the complete conversion to a 10-rib system on the C7 LT4 blower drive and includes everything needed except the upper pulley. Please note that this adds one rib forward and one rib back compared to the stock 8-rib drive, so your upper needs to match this. You will need to specify the size of the lower pulley you'd like with the system.

Included in this conversion:

GM LT5 tensioner (~20% more tension than stock LT4)
GM LT5 tensioner bracket w/ smooth idler
GM LT5 90mm smooth idlers
DSX 89mm (OEM diameter) ribbed idler for tensioner bracket
DSX 70mm (OEM diameter) ribbed idler for water pump
DSX Anysize 10-rib lower for ATI 917315 damper
