Thread: Rear lateral arm question

Noticed one of my lateral arms was bent(previous owner may have had the car towed at one point). Id like to take this opportunity to upgrade to better arms. My questions are 1.are the stock ones hollow or solid? 2. If they are hollow do companies like dorman or moog make solid ones? 3. Do 9c1 impalas have better arms then our cars?
Im not really interested in the bmr or umi arms. I know they are great but still too expensive imo. The w body store ones are more fairly priced, but I like to weigh my options. Any help is always appreciated.
Thanks

Stock are just stamped steel, not very strong.

Dorman units are just a solid bar, loads better than the factory stuff.

lateral arms are solid steel 4 of em, in parallel pairs, from the center cradle to the lower portion of the knuckles. the trailing arms are the ones from the unibody in front of the tires to the single point on the bottom of the knuckle

Eh, I'm thinking trailing arms. One of them days.

Yea, the lateral arms (the four arms from the crossmember to the knuckle) are the ones im talkin about. My passenger arm with the adjuster bolt is the one thats bent. Now to replace them do I have to drop the subframe or no? Through searching ive seen some say they had to drop the subframe and some say no. It looks like it varies as far as which wbody car you have, so where do grand prixs like my 01 fall into?
