The BDS 4.5" XJ Long Arm system provides the best on and off-road capability you could ask for. By maximizing the length of both the upper and lower control arms, BDS has minimized caster change for optimum handling and minimized road forces transmitted ultimately to your seat for the best ride. To give you some idea, the lower arms are nearly bottomed out at just over 32" and the uppers at just over 28". This is about double the length of the factory control arms!
Although this XJ long arm system makes for a great daily driver, the true abilities of this system won' t be appreciated until you hit the rocks, dirt and mud. The 4-Link design maintains better axle control through wheel travel than any radius arm system because the upper to lower link relationship is not fixed, yet is tuned for optimum performance based on link length and operating angles. The control arm geometry is setup with the massive belly pan that incorporates the link mounts and is built to smash rocks. Believe it or not, this system is completely bolt on with no welding to the unibody required!
BDS Pro-Ride Coil Springs, capable of withstanding full coil bind and a tuned rate lift the front. The rear is lifted with new Glide-Ride Leaf Springs and extended greasable shackles that really let the springs flex.
This system also incorpoartes BDS Ultimate sway bar disconnects for quick easy access to rediculous wheel travel and stainless steel brake lines to handle it. Bump stop extension are included to limit compression and keep the tires out of the fenders on the trail. A front adjustable track bar with flex joint fits into the existing frame mount, so drilling of the taper is not required and will allow you to accurately center the front axle.
This system is available with both flex and standard control arm bushings, NX² series or Fox 2.0 series shocks, and many other upgrades. To check it out all of the options BDS has for your XJ, customize your kit and see what our competition is up against.
If you truly want to do it right the first time, install the BDS 4.5" Long Arm system and have no regrets.
