Most "cost effective" nitrogen charged stabilizer kit that will perform well is the BDS brackets and Bilstein 5100s for the stabilzers..... $280.85 for that combo
Still may be more than what some people are looking to spend. Nitrogen charged shocks are what help drive the cost up, but are also why the kits work so well.
As I mentioned in my first post....the Icon is just cleaner looking with the laser etched billet clamps used on the tie rod instead of steel plate and u-bolts. Also has the clear coated stabilizers (if you live in an area with a lot of road salt).
