Completed the LCA install this weekend and all I have to say is what a PITA! Not sure if other arms come assembled or not but these Mega Bite Jr's were an absolute whip! I do have a question though...before the install I had a very slight whine from the 4.30's at higher speeds...say 75-80 mph...now that seems to be amplified somewhat..could it be because the LCA's are soo much more beefier than the stockers that it is just transmitting the noise more?? Besides that all is good! Thanks for any input...
