3" JK Lift System - The JK family uses 22 different factory coil springs, each with a slightly different rate, dictated by how the JK is equipped. New Black Diamond front rear coil s provide the lift. The largest jump in spring rate is from the 2 to 4-door model so we offer a heavier rated rear spring for the 4-dooor. Lift height can vary slightly (up to 3/8") depending on your factory spring rate. You can use rear 4-door coils on your 2-door to offset extra weight.

As the JK is raised, track bar angle increases and when lift height exceeds 2" bar length becomes an issue. Bar bind causes the chassis and axle to continuously "tug" against each other resulting in uneven ride height (side-to-side) and "roll and yaw". Front correction is accomplished via a new adjustable track bar. This route is preferred, as opposed to using a relocation bracket, since the bar's arc of travel must remain in sync with the drag link's arc of travel of steering wheel "kick" will result. A relocation bracket is used at the rear axle since there are no steering geometry.

The stock JK has no provisions for caster angle realignment, which is required at this lift height, so Black Diamond provides new alignment cams. Note that factory caster angle can vary substantially from one JK to the next, so it is possible that the furnished alignment cams may not yield sufficient caster on some JKs. In these cases optional, longer axle-to-frame lower links must be used, which are available in fixed-length or XT Swivel Link versions.

Compression travel is controlled via new OE-style closed-cell foam stops while new shocks (three different levels of performance and price offered) improve control and restore full extension travel. The lift system also includes longer sway bar links with factory style tie-rod type upper ends, front /rear brake hose relocation brackets and emergency brake cable brackets... nothing is left unattended.

To maximize the JK's off-road prowess, our award-winning Xtreme Terrain (XT) swivel links and anti-sway bar quick-disconnects make the most of an already formidable suspension design. An adjustable rear track bar, and a high-clearance replacement steering stabilizer are also available. For more information on these and other Black Diamond accessories available for Jeeps, check out the Optional Accessories pages.

Generally, caster angle is adequate at this modest lift height, although if caster is "light", optional alignment cams are available. Other options for increasing caster are longer, fixed-length front / lower axle-to-frame links, or high-clearance XT swivels Links. If replacement lower links are used, alignment cams are not needed.
