I am replacing both the lower and upper control arms on my 99 blazer 4wd LT and I am having problems finding the correct parts. What rock auto lists as working for this model don't fit per some reviews I have read. It looks like none of the moog control arms will fir (I think they are ZR2 parts). I am looking at either moog or dorman, not too many other options available. Thanks for the help

 

These should work

 

That's the reason I am asking. Most all of the rock auto part numbers were not a fit per amazon. Does anyone know about prime choice? Seems kind of cheap

 

Dont really think there is a supsension difference between the lt and ls

 

From what I have read, the difference is in the sway bar bracket. Rock auto has a bunch of moog arms but on amazon there are none.

 

what is the difference between the lower control arms on a

 

Interesting read, I know there isn't a difference with the LS and LT but there is with the ZR2. It just doesn't say which is different on any of the moog parts on rock. There is one set of the dorman that say with high rider package but that's it. I appreciate the help

 

I have purchased and installed two sets of MOOG RK620300, RK620464, CK620172, CK620173 upper and lower control arms from Amazon. I replaced the riveted lower non-serviceable ball joints with the K5335 greasable ball joints at the time of installation. It was cheaper to do it that way. I had no problems with either vehicle. The parts were the same shape, size, fit, holes etc... As the OEM parts I removed. I have no clue what those people are smoking that left the Amazon reviews, but these are not ZR2 part numbers...

I can only tell you about my successful experience and can't speculate on their failures...

Hope that helps!

 

I appreciate the info, that helped a lot. I am going to order this week. How bad of a job was it, I have all four controls arms, the shocks and 1 axle to replace. Looks like a busy weekend lol.

 

Not to bad, take your time.
