Limited Slip Differential?
Does anyone know what type of diff we will get? Clutch pac, cone or gear type?

Although not the greatest the cone type was used on the '04-'06 GTO. Gears may be a bit noisy however they are less maintenance over the long haul.

I had been looking at that since it was teased a while ago. While I'm not trying to take anything away from Lingenfelter, ZL1 will come with a strengthened iron differential case, and I'd seen the mention of a 14-bolt from the factory tours. AAM, who makes Lingenfelter's diff', is generally the same company that GM uses for a lot of their SRAs. If you look for reference to 14-bolt ring gear sizes, they start as much as 9.5" in diameter. These were used in "heavy" half-tons and "light" three-quarter ton trucks 14-bolts go as high as 10.5" in diameter if I remember correctly, so if we see a 9.5" in ZL1, I'm not certain, unless your power/performance goals were astronomical, that many things outside of bushing, rear diff' cover (like LPW), and axle upgrades may be necessary. I definately like Lingenfelter's case is aluminum though. Looking at all the ribbing, I'm certain it's strong as Heck, and if they use this monster in their LS9-car, then I know it's plenty strong, lol. +1200 RWHP with N20 and a stick ain't doing any favors to that rear, lol.

Thanks for the comments on our Diff guys. It will be very interesting to get one of the ZL1s and weigh their iron diff in comparison to our Aluminum version to see the differences.

No this is not the same differential. The LPE differential is a unique piece that we have done the R&D in conjunction with the manufacturer. |
