BDS control arms come standard with OE grade rubber bushings. If you would like to upgrade, BDS offers adjustable arms with urtethane ends or adjustable arms w/ flex joints to fit your needs.
To improve the steering and handling geometry, BDS includes a front track bar relocation bracket and a dropped pitman arm. Fixed swaybar links are included for Rubicon models with the factory disconnect system, for non-Rubicon models choose between BDS Ultimate Sway Bar Disconnects or JKS Quicker Disconnects. Specific for 2012-17, BDS exhaust extensions are included to maintatin front driveshaft clearance at full droop.
In the rear, an axle mounted track bar relocation bracket is included that has a built in support gusset that ties into the bump stop pad. JK's are known for broken welds on the factory track bar mount when wheeled hard, so BDS solved the problem with this added support. The kit comes standard with NX² series custom valved shock absorbers for a smooth ride.

No Fine Print Warranty
BDS stands behind its products and that’s evident by their No Fine Print Warranty. This no-BS warranty protects the original purchaser against breakage, bending, sagging, or any other usage failure. This “no fine print” lifetime replacement warranty extends to cover all BDS hard parts as well as bushings. Exclusions would be product finish and wearable items such as shock/stabilizer cylinders, tie rod ends and ball joints that would fall under the separate Limited Lifetime Warranty policy. Beginning February 1, 2020 all new kit purchases include the No Fine Print Warranty on bushings.
Limited Lifetime Warranty (for wearable items)
Wearable items include shock/steering stabilizer cylinders, ball joints and tie rod ends. BDS Suspension Co. warrants to the original retail purchaser that its these wearable parts are free from defects in material and workmanship for so long as they own the vehicle. Excluded from this warranty are the finish of the product. Defects in material and workmanship do not include such things as dented cylinders or bent rods caused by obvious side impact, rust or corrosion. A shock absorber is a wear item and over time will experience diminished damping resistance due to normal component wear. This is not a defect in material or workmanship and is therefore not warrantable.
