So we ran into a great deal on Craigslist and I managed to get LC Torsion bars, Rear Springs, and Rear shocks for $100! Today we swapped out the 25MM TBars and installed the LC 28MM Tbars. Definitely made for a change. Feels stiffer and less floaty. As I was deciding to swap out shocks I see that the truck has 29-4499 Bilsteins on the rear already. Trouble is I cannot track down that Bilstein # so have no idea if the LC shocks are any better. The LC shocks are 48511-60492 SG1 Tokico Japan. Also it appears when I caliper the springs they are the same diameter as the LC springs. I think perhaps the Previous Owner swapped to LC springs, and LC Bilstein Shocks, and just left the Tbars LX470 part. Any advice on these Bilstein Part numbers?? They show a date on the Bilsteins of 10/12/12.
