Lt1 and ls1 rack and pinions handling difference Hi all,
Sorry if this was already discussed, couldn't find any info.
I have lt1 Camaro and I'm going to replace rack and pinion.
I found 3 options on Rockauto:
ACDELCO 36R0369 (2 5/16 turns lock to lock)
ACDELCO 36R0391 (w/ Ride & Handling Suspension (FE2, FE4, FE7))
ACDELCO 19330435 (Ride & Handling Suspension (FE2), SPECIAL SUSP (FE4))
The first one is lt1, others are ls1.
Is there any difference in performance, handling, response etc. between lt1 and ls1 rack and pinions. Is it worth it to buy ls1 rack?
What is the difference between second one and third one?
Are there any other good options?

They aren't all interchangable. Check out this thread: https://ls1tech.com/forums/suspensio...ck-pinion.html
To decypher the rest, you need to go to the AC Delco Parts Catalog to get the rest of the details that RockAuto isn't giving you. (They have a great catalog but don't have 100% of the part details, so I find myself doing this all the time!!!) https://parts-catalog.acdelco.com/acesCat.php?
If you lookup the parts on AC Delco and reference what you see on RockAuto, you'll find that the first part you list is for the F41 suspension, the second part is (FE2, FE4, FE7), and the thrid part is the lower (OE) quality version for the (FE2, FE4, FE7) suspension. The first two are "Gold" parts.
