The Rusty's 3-inch XJ Suspension Kit has been one the most successful items we have developed. Our soft spring rates along with our specific valve shocks have put this kit above the rest. All of the Rusty's 3-inch kits will clear 31in. tires. Rusty's 300AL kit comes complete with front coils, full-length add-a-leafs, four Rusty's hydro shocks, a rear brake line extension bracket and complete instructions. The Rusty's 300SP has the same parts as the 300AL but with complete new rear springs. A new addition to the Rusty's suspension line is the 305STS kit. This kit comes with coil springs that have a 30-lb heavier spring rate and an overload spring on the rear leaf springs. If you have a large heavy bumper, a winch, and carry a lot of gear this may be the kit for you.
Price: $438.00 Pros: Easy install. Works Great. Cons: Brake line extension wasn't very straight forward Recommended? Yes
Comments: This was my first suspension install. I managed to get it done in two full days. The install went fairly smooth. The only things I would say gave me trouble were shoving the bushings into the shocks and extending the brake line. I ending up not installing the brake line extension and just cutting the stock bracket off and having my mechanic extending the hard line.
Price: $448.00 Pros: Full leaf packs, budget shocks, price point is really great for an entry level kit. Had everything I needed, easy to install on a rustbelt XJ. Cons: Minimal vibes, no bump stop extensions or new control arms. Not the best shocks in the world. Recommended? Yes
Comments: For me it came down to price. between Rusty's and IRO. In the end I just didn't think the IRO kit was $300 dollars better than the Rusty's kit and just couldn't justify spending the extra money for it.
You can upgrade the shocks on this kit to Bilsteins which I'm sure are worth it, but not for 400 dollars! I wish this kit came with some fixed length lower control arms to add strength. I have minimal vibes with the kit but it is really livable. I didn't need to replace or re-drill a hole for the track bar. The stock track bar fit just fine.
I have a T-Case drop. I might use it, I might just live with it. We shall see.
