Suspension RPO code question

BDS, ReadyLift, Smaxx... You name it, we know about it here.

So I'm gathering info for my TB as I'm hopeful that I will be able to lift it shortly and i have a question regarding the RPO codes for the front suspension.

I have read TrailX's post about the factory springs and the RPO codes.

My RPO code is not listed in that thread.

Mine are 6SK and 7SK and this is what i have found so far

6SK COMPONENT FRT LH COMPUTER SEL SUSP (6SK)
7SK COMPONENT FRT RH COMPUTER SEL SUSP (7SK)

My TB is a 2002 LTZ. Has anyone seen these codes before?

I'm thinking my front suspension is computer controlled but I would assume that it is something controlled by the computer without drive input as there are now selections for suspension that i am aware of.

Is there anything i should be worried about with these?

Computer controlled front suspension? Not on a 2002

That’s what I thought. I have not been able to find anything else on those RPO codes. The original front springs are long gone as the struts that are on it now are cheap replacements. I’m going to try and find some 87 springs and get some bilstein 5100 shocks.
