even though the springs say they are 15% stiffer, they dont feel like it because it is a bigger spring and it will ride softer than stock. the spacers will make it stiffer because you are 2 more inches in there but not 2 more inches of spring. IMO, get the rear springs and shocks, it will be a much more comfortable ride. my rear springs are 30% stiffer than stock, but the ride is 50X better than the stock ride. and you get virtually NO body roll on turns compared to stock.

Thanks, Mike. That's exactly the kind of info I was looking for!

for the front you should get the upper a-arms IMO, it will help a lot with your allignement.

Normally, I would agree with you, but I remember reading this post in another thread, which is why I was leaning towards the stock uppers.

Just to clarify, the upper a-arms are not required for alignment issues on US spec FJ's, they ARE required for Canadian models. For some reason Toyota used two different arms for the US market, the FJ and 4 Runner got arms that have the same geometry as the aftermarket arms, but the Tacoma got the straight arms at the ball joint area that causes them to bind when lifted and pul the camber way out of whack. Canadians got boned and got the Taco arms on the FJ, so they have to swap them for anything more than about 1.5" front lift.
The Chromoly arms DO however give you added strength from a tubular design vs. the OEM "C" shaped setup, the urethane bushings deflect less but last longer (but are harder & tend to squeak more when not lubed, but we provide zerk fittings for grease) and the Uniball requires monthly oiling to kep squeaks down. It is a straight bolt through the uniball instead of a tapered fit that stays tight, so slight rattles are possible, but they are replacable when worn at $49 each.
We are also just discovering that Canada also got longer rear lower shock studs on the axle that cause play at the bushing. The US spec FJ's have each side of the lower shock bushing touching a washer when installed, but the CDN models have a 1/2" gap at one end that lets the shock "float" on the stud. Spacers made from the old OEM shock bushing need to be made for those models.
We cant figure out why Toyota would make both those items different for North Amreican FJ's, but they did.
