Nope. Oil cooler, yes, auxiliary coolers for the engine coolant, no.

No additional cooling components on the LT1 in 2020. 1SS added all of the additional pieces.

For 2021 MY, the LT1 added the oil cooler.

My 2020 LT1 has the oil cooler via build sheet and since it has the 10 speed has the tranny cooler as well.


EDIT: Located the Build sheet for my 20 Camaro LT1 and these are the codes

KC4-For the engine oil cooler

KD1-For the Transmission cooler

Interesting. The product brochure lists nothing for cooling for the LT1 but shows the 1SS as being the first model to get:

- extra-capacity cooling system and external engine and transmission oil coolers (requires automatic transmission on SS Convertible)
- auxiliary engine coolant cooler and rear differential oil cooler (Coupe)

In the 2021 brochure, the LT1 shows:

- external engine oil cooler

And the 1SS still shows:

- extra-capacity cooling system and transmission oil cooler (requires available automatic transmission on Convertible)
- auxiliary engine coolant cooler and rear differential oil cooler (Coupe)


I wonder if the coolers you have are the standard capacity / non-auxiliary ones whereas the references above are for ones that are "upgrades"?

Not entirely sure but I also noticed the oil cooler not being in the 20 brochure but it was on the build sheet and my friend put it on his lift for me and showed me the tranny cooler and then he showed me the oil cooler lines. So they are there. I know the Manual does not have a tranny cooler in the LT1 so that is probably why the tranny one isn't mentioned but not sure why the oil cooler wasn't mentioned in the 20 brochure since I am sure the manual LT1 has it as well.

Then why did my 2023 camaro LT1 come with 9. 5 in. Rear wheels on it

[TheEnthusiast]

Wait...according to pics of the dash, why does the LT1 have a 7k rpm redline?

SS has 6.5k redline, confused

This threads a few years old, the original info here was solely from documents as there weren’t any LT1’s out in the wild. The photo used early on in the thread was from a I4/v6 car just to show the style of gauges. The actual LT1 has the same rev limit as the SS just in the same style as the I4/v6 gauges.

Here’s an actual LT1 gauge cluster

That is strange (but good for you!) - My guess would be your dealer swapped them from an SS for some reason?
I assume it also came with SS size 275/35/20 tires?

And was it the all season run-flats (w/LT1) or w/summer run-flats (SS)?

Do you have window sticker and does it show any package/option that added 9.5 rears w/275's?

I'm pretty sure there are no packages to add the offset wheels to the LT1 from Chevy, so it would have been something the dealer did. Maybe they had a full set of take-offs from an SS and put them on the LT1 and added it to the cost?
