2001 suburban 1500 and 2500hd control arms

[Adampsl]

Hello new to this site

I have a question, i own a 2001 suburban 2500 8 lug and was wondering if the control arms are the same as a 2005 1500. ? I know the spindles are different (3 bold for the 6 lug and 4 bolt for the 8 lig) but wondering anout the control arms, i found a guy selling a lowering set of upper and lower control arms off a 2005 silverado and wasnt able to find out if they will bolt up . It looks like the lower control arms have the same part number looking it up on auyozone but the uppers had different part numbers. 

Thanks for any help with this.

Go to 1aauto.com man.  I've never had a mismatch part issue from that website.  Been buying parts for my 04 Silverado from them for years.

maybe also check on rockauto.com and compare part numbers.
