Eibach-no go on 05 and later
GM moved the front bar into the frame in front of the oil pan. I bought the Eibach set a year ago and the Eibach front bar cannot fit into the 06 mounting location. It's a hollow bar, which is why it's so huge. Did you notice it won't even fit inside the stock retaining brackets?
The only good news is the rear Eibach bar is bigger than the competitors, it is solid, and it fits good. I like it but it sure was expensive since I had to buy the pair.
I hounded the Eibach product manager and production manager for 6 months to twist up a late model front bar and they finally made a corporate decision to not support the late application. Their inventory control system can't even track the difference cuz they're too big as a company to communicate internally, and they don't care. Our volume is way too low compared to the ricers and other product lines.
I'm looking forward to back to back testing of the addco to see if it really is stiffer than the SS front bar. NORCAL, time to get dirty and get it on!!!
