LSA Crank pulley on SS
Anyone know what would be required to install a LSA lower on an SS? The car is a 2011 L99 with an LS3 conversion. I’m wanting to put an overdriven lower on it to make a little more boost with the LSA blower but nobody really seems to sell a 6 rib overdrive pulley (specifically considering 8.6” or 9.2”). Anyone know what I would need to do to make it work? I know I can do the 8 rib conversion but I’m sort of trying to avoid that because I would like to go turbo at some point and I don’t want to put the money into an 8 rib that I’ll probably later remove. Thanks in advance

LSX sold me the one I have. It was a member here on the forum. I have the ZL1 lower on mine. I run a 6 rib on the middle of the pulley. 50,000 miles some I did it, no issues, no slipping.

LSA Crank pulley on SS
Quote:
Did you only install the lower or did you have to replace other pulleys or use any different brackets/adapters? What pulley combo are you running?

I ran a Powerbond SFI 10% OD balancer (8-rib) on my truck while everything else remained on the 6-rib pulleys. On my truck it is a single belt that drives the accessories and the blower.
Here is a link to one of their dampers for an LSA setup: 10% OD Balancer

Everything lined up properly? From what I’ve been reading it seems like the LSA pulleys don’t sit out as far as the rest of them

All I had to do was install the LSX tensioner and the ZL1 crank. The kit comes with a spacer for one of the pulleys, can’t remember which one.

I run a 10% OD Innovaters West. It is 8 Rib but I run a 6 rib singe belt with a 2.40 upper.
