Rear suspension part numbers help needed - LC100 (1 Viewer)

[katit]

Need help here. Spent hours before and today and couldn't find what I need.
I need specifically US spec, 2001 LC rear springs and shocks part numbers so I can order them in current sale.

I've been looking at Partsouq catalog and there is multiple different PNs listed. For front I think I got correct one:
Front shock. Contains bushings
48511-60510 - this is "MAIN" pn showing on list/description but not pulling any parts on dealers sites
48511-69477 x 2 - this seem to be "current" regular shock. It looks up PN 48511-69585 and seem to be the only one and correct.

With rear is not so easy..
48531-60560 or
48531-60690 - those 2 "MAIN" pn
48531-69567 - looks to be "current" regular shock - not looking up on Sierra
48531-80688 - this is what looked up on Sierra but "may not fit"
Anyone? What is a correct current PN for rear shock?

Rear springs is even worse... I know it's different height. But WHICH ONE WAS STOCK IN US?? Or which ones (I kind of remember they are different L/R?)

Is this an LX or an LC?

What month build?

This is going into my LX (2001) which has AHC delete with aftermarket stuff. I want to install all LC parts. Rear springs/shocks and front shocks. Front torsions already replaced (will keep)

I assume pick "any" build month, won't matter. Just need all OE stuff as it would be on LC

That's easy enough. Thanks for clarifying your situation.

Rear shocks: 48531-69835 x2 (These will not come with the metal bushing retainers. Either reuse or get new ones)

Rear springs: LH spring will always be taller in a USDM truck due to driver position (usually a few millimeters)

RH:

48231-6A660: 486mm tall
48231-6A680: 498mm tall

LH:

48231-6A670: 492mm tall
48231-6A690: 504mm tall

Just pick which ones you want in terms of height.

I would also make sure to get: 48267-60020 (rubber vibration insulators for the tops of the springs)

And you can level out the rear using factory spring shims: 48373-60010 (these are about 10mm in thickness, IIRC)

Thank you!! And yes, with my situation now I am concerned with washers.. Who knows what they put in there, and I know LC/LX different.
I'd rather get all new. Does this list below look legit?

will the OEM shock give me a more comfortable floating drive feeling?

Hi, I finally can not take any more of my LC100's aftermarket "OESpectrum" shocks. this shock set came from the previous owner, he said it is better than the OEM because it is harder, but one of the reasons I want to buy the LC100 originally is that I heard this car will have a very smooth kind...

Also, in terms of rear springs. Truck is driven mostly on a pavement. I see you listed 2 pairs to choose from. Which ones were installed from factory? Lower? It's my daughter car, we don't really tow anything or load it whole lot. Does it mean lower springs will be correct choice for best ride quality? Or get taller but don't need any spacers for sure?

@OGBeno Thanks again! Question about spring size answered by itself. Dealer (Decatur) only lists larger ones available, so be it. Order placed.
