X2 Tech: Generally, coil springs and / or coilover shocks offer increased suspension travel and compliance compared to standard leaf springs, but at a price; coils at all four wheels increase body roll, plus they induce excessive lift while climbing, and excessive dive during down-hills. The X2 uses either coil springs (TJ) or Superlift's new progressive rate coilovers (YJ, optional for TJ) in conjunction with 4-link long arms on the front suspension, while our unique leaf spring-over-axle design supports the rear. The end result is a system that attains a never-before-achieved combination of stability, articulation, ride quality and control. It's not just a matter of increasing suspension travel... the X2 properly controls this additional travel to provide the correct amount of vehicle weight transfer at the right time, resulting in stable, predictable handling characteristics on any type of terrain.

Rockrunner™ Long-Arm 4-Links
(1) Arms' profile provides exceptional clearance and full lock-to-lock steering
(2) All 4 arms feature swivel-link ends, and steel-encased rubber bushings at certain link mounting points for optimal bind-free articulation, vibration dampening, service life and noise-free operation.
(3) Link arms bolt directly to the stock TJ axle housing. Bolt-on brackets (shown) used on stock YJ axle. Weld-on brackets available for all popular front axle housing upgrades
* Arms' design and flat operating angle create ideal weight transfer characteristics and alignment geometry
* Made of 0.188" wall DOM tubing (lowers 2" OD; uppers 1.5" OD)
* Longer optional female swivel ends for front arms offer wheelbase increases in 1", 2" and 3" increments
2-Piece Skid Pan - With most suppliers, providing access for routing drivetrain maintenance and adequate room for exhaust routing is not a consideration; not so with the X2. Drop the full-width, full-length primary pan to access U-joints, shifter linkage, even transfer case removal, and the X2's inner pan remains to support the transmission. The rear ends of the 4-link arms remain anchored to the frame rails.
(4) Primary (bottom) pan constructed of 0.25" plate steel and secured with flush-mounted fasteners
(5) Inner pan constructed of 3/16" plate steel
* High-clearance, tight profile
* eXtreme clearance Flat Pan option available; requires high-pinion diffs, body lift and/or tranney tunnel modification
Rear Springs - Specifically designed for this spring-over-axle application, the functionality of the X2 rear leaf suspension assembly is light-years ahead of a common "spring flip." Combined, these features offer the ultimate in ride quality, durability, quiet operation, wrap-up prevention and controlled articulation.
(6) Triple military-wrap main leaf eyes with factory type, steel encased rubber bushings
(7) Extra long (7") spring-to-axle pads
(8) U-bolt plates with integrated compression travel-stop brackets
(9) eXtreme travel spring shackles made of 0.25" plate steel
* 9-leaf design with bolt-type spring clips
* Tapered leafs with anti-friction insulators; each leaf is shot-peened and pre-set
Other Primary Features
(10) Reservoir gas monotube coilovers (shown) feature Black Diamond's revolutionary progressive rate springs to improve ride quality and reduce lift force when climbing obstacles. Our progressive rate coil operates noise-free; not so with dual-coil designs
* This same basic coilover conversion is available for the TJ or retain the TJ's standard coil/shock design
(11) Dropped pitman arm, track bar bracket, brace and adjustable track bar provide ideal steering geometry. Works with tie-rod in stock location or "flipped"
(12) Compatible with stock diff cover or use with optional Superlift eXtreme Ring diff cover protectors
* Black Diamond SS series monotube gas rear shocks
* Includes front / rear Kevlar reinforced, braided stainless steel brake hoses
Optional Torque Fork - Torque Fork's unique "triple axis" design controls wrap-up throughout the entire suspension travel cycle without sacrificing articulation. The Fork is suggested for vehicles running 37" or taller tires and/or for rigs with high horsepower, high torque engines. Fits TJ, YJ, CJ, Scout, early Bronco and older Toyota FJ series; all must have springs on top of rear axle
(13) The Forks' front (skid pan mounted) shackle allows a slight amount of fore / aft movement as the suspension compresses and extends
(14) Swivel end further promotes bind-free articulation
(15) The rear, axle-mounted shackle allows a slight amount of pinion movement before locking-out axle wrap
(16) Adjustable main beam enables you to perfectly set the assembly's geometry for your particular vehicle
