Yes they come with everything you need [brakelines are an additional $65] which you dont need when installing up to +2 arms on a 450. I have the race series that is fully gusseted "reinforced" and come fully camber/caster ajustable for $575, and I also have rec arms that are exactly the same arm minus the gusseting and minus the caster ajustment on sale right now for $475 , however, I do recomend the race over anything, you get 16 more pcs and twce the amount of labor goes into them[you get alot for $100. You can compare my race arms to like a Laeger set of arms, but at a much better price. Their price retails at $850 for std shock +2s with no caster ajustment. If you want caster ajust, you would have to add $150 making a grand total of $1000 for theirs.
