ZL1 Vert Axles - Same as coupe?

phaedrus · 02-09-2020, 07:04 PM

Looking to replace/upgrade the axles on my 2018 ZL1 Convertible. Obviously our Verts don't have an e-diff... Are our axles the same dimensions as the coupes? I ordered a set from one of the more prominent vendors and the passenger side axle they sent me was 7/8" shorter than the OEM axle and obviously didn't work. I'm not sure if this vendor had a bad day or if our cars require a different length and this vendor didn't know it. Verts are rare, after all.

GForce hasn't launched their ZL1 axles yet and won't until mid-2020 when I spoke to them in late 2019, so trying them isn't an option yet.

Thanks in advance!

I have the same question, AFAIK the left side part number is the same, the left side for all ZL1 PN 846372865. I don't show a different shaft from the SS diff (no eLSD) and the vert 1le / ZL1. So I don't know, if you by chance to be under there it would be interesting to verify the axle shaft numbers. The stock left side SS no eLSD shaft is 84309457,
