I have heard that the redline on the trucks is 5900.

Does anyone have any knowledge on this? I would like to know where to set my rev limiter.

 

I believe the first to second shift is raised to 6200 RPM and Third to fourth is like 6k or so, anyways I believe that rev limiter can be set safely to 6300. Maybe Wheatly will chime in on the matter.

 

The GM website says redline is 6000 RPM for the 6.2L.

 

With the stock cam, I had mine set at 6400 and the 1st to 2nd shift at 6100 and the rest at 6000. I have the limiter set at 7100 now and it shifts 1st to 2nd at 6800-6900. Its the stock valve springs that are the limiting factor.

 

yeah i would love to know!

 

Just found this:

i spun mine to 6800 all day long with no issues and a couple 7000 with no problems. im back down to 6500 bc of the stock 6L80e i put in my truck

 

The limiting factor will be the 6l80. GM recommends max rpm at 6200 for the 6l80. I have heard of problems with the trans above that RPM.

 

LS3s redline at 6600, whether they are mounted in front of a 6L80E or a TR6060

 

LS3 is still using a 6L80E, they have a max rpm of 6500. every website i see says 6500, an there are a few A6 vettes running 7k all
day long and pushing way more HP/TQ than me. ill
stick with my 6500
