I'm a college student with a moderate income and have saved enough for the LA 4.5" RE kit with shocks, SYE/CV, and still have some $ left over. I'm wanting to run 35s. I'll be replacing the 3" BL and still running 33's. If I go with the LA kit then it'll be longer till I can offord to upgrade the axles and put on 35's, but if I go ahead and get the SF kit then I can run 35's as soon as I get the lift and upgrade the axles. I don't want to get into all the things about axles, gears, tires, etc. just deal with SF vs. LA please. Could I run a different shock than the monotubes and have a LA like ride with the SF or is there no way to possibly get the LA ride out of a SF? It's a DD and want a smooth ride...
Having run both the RE SA and LA, on a budget I'd go with the SA kit. The ride is not that bad with the monotubes. You can always upgrade later to the LA, if needed.
Don't forget about better brakes with the 35's though.
X2. I've got the RE 4.5" SF kit and I like the way it handles. I personally feel it's better than stock. Don't worry about the ride! Those people who make the ride such a big deal are the ones that have to worry about their back when they get out of bed j/k. You can always upgrade LA later, but I feel you will be content with the SA kit.
