10 Rib belt not included
, please see belt reference guide below. All recommended belt lengths are based on 66mm supercharger pulley and 90mm FEAD idler, your belt size may vary:
|Lower manifold year||Belt without AC|
|2015-2017||k120702 (remove 2 ribs)|
*SC pulley purchased separately, 10-rib blower pulleys available in 75mm, 69mm, 66mm, and 63mm (VMP blower only). Selecting the dual key way option may delay shipment as the second key way is added to the balancer after receiving the order.
Installation is as simple as swapping all the included pulleys. Grinding of the front cover must be very good, and in the case of the upper boss and ribs, flush. The AC clutch should be shimmed .015-.020"" of clearance, basically where you have to rock the cover back and forth for it to touch the face. There needs to be enough room for the face to get a running start when the magnet powers up and pulls it towards the AC pulley to engage the compressor. Pulleys should be installed with the snap-ring facing out or visible.
Roush snouts will need machined to accept 10 rib pulleys. VMP TVS snouts are machined back 2.550" from the hub face. Customers using a 63mm pulley will need the hub and snout diameters machined down to 2.120-2.130". VMP TVS snouts are already this diameter (with some early model exceptions).
