I got a tip that the tensioner pulley on the '08 LS3 in
'vettes is a high-lip one, and might be a good "cheap"
way to go vs an aftermarket one. But I haven't been
able to chase down a good part number online and
the aftermarket auto parts places are showing me the
same P/N as for the one on my Camaro.

Does anyone have GM parts manual or parts system
access, and could give me the P/N for the new 'vette
pulley?

The GM part# is 12569301, and it does have a taller lip than the regular LS1 tensioner.
This is the tensioner used on the 04-07 Caddy CTS, and 05-08 Vettes.

We make them out of 6061 billet....look & work nice.

Is there any benefit to using this besides reduced risk of throwing a belt?

throwing belts? I've been on this board since '02 and this is the first time I've seen this issue...have I not been paying attention well enough? I've never thrown a belt and this is my 3rd 98+ F-body.

I threw the belt on mine on track (usually a problem only with higher RPM). I tossed the belt at 6500+rpm and it broke my lid, and damaged part of the radiator (not always a problem I'm sure, I just was unlucky). All that ON TOP of the fact that I lost power steering and drove off course at 100+mph hitting a cone which broke my foglight and scuffed the bumper

I just put the pulley from a supercharged mid-late 90s regal. It works well and lasted longer than the motor did!

We can make them w/a higher lip if needed to help prevent this.

a high lip pulley is a very good idea, when i started making a lot of power it was a MUST for me. i don't know what i would do without it.

I have owned 3 as well and never threw a belt, but this was the only benefit I could see to using it. It doesnt look underdriven or anything special.

Less chance of distortion (the OEM one is plastic) and the looks & quality are a plus.

In stock ready to ship!!

Is this a direct replacement from the stock pulley? How much do they run if I may ask? Traver

TLewis4095

iTrader: (10)

Yes, just unbolt the stock one & bolt this in place. $49.95, call JP to order: 813-628-0080

Thanx TLewis! I ordered it today. The stock LS3 one was the same price so why not go the billet route, right!? Traver

price went up to eighty since the last post?

My 99 H/C SS would throw belts every once in a while due to extreme rpm I guess, or it simply reved that much faster with the cam that the belt would walk...

I used a single lock washer to space one of the bolts but now thinking about it, I think as the spring inside the tensioner itself ages, it bends/wears slightly crooked. Either way, it happened on a regular basis on my SS.

Mine revs to 7 grand without throwing belts. I have a steel tensioner pulley from a 6.0. I don't know if that has anything to do with it or not. Here is a picture of my setup
