I’m looking into a few options for building up my 2018 SR5 and I wanted to know a few things before I go forward. 1) I’m looking at a used 2017 TRD OR suspension with about 10,000 miles on it. It’s comes with the front Bilstein shocks and coil springs, the Rear Bilstein shocks and leaf springs as well as an add a leaf. It’s affordable but I want to know if there is a significant difference between the SR5 and the OR other than the shocks. Are the leafs and coils heavier duty or are they basically the same? In the future I’d like to do a 2.5 in lift on the truck but money’s tight now and I’m getting the itch to do something to the truck within reason. 2) I’m also considering putting either 275/70R16’s or 265/75R16’s on the truck in addition to this set up. I’m not looking to do the cab chop at this point and I’d really like to stay away from spacers. Is there anyone here that has done this and had good results (no rubbing) and if so, what are the brand of tires would you suggest. If there are any related posts on here you can point me to that would be greatly appreciated.
