It would be nice to have a post devoted to Acronyms for reference from time to time. I just threw a couple of common ones out there. Please feel free to correct me. Also, please post the ones that come to your mind or PM me. I will edit the 1st post to include what you've added and keep them alpha/numerical order.


Not that I am looking to maintain a "G" rating, but would like for this post to be useful. If a suggestion gets too stupid or plain vulgar I won't edit the post. You will have to start your own post.


Hope you find it useful, interesting and maybe even fun. Here we go!

lol, you are right, what i meant to find out is if Strut Rod is the same as a torsion bar.


That is what tells you to look at Push Bar.


Im assuming its the same as above, where it just says strut, it lists a bar connecting the LCA to the frame.
