It's Your Jeep, Only Better
JK Wrangler 4-Link Long Arm Compound Suspension System, 4.5"/5.5", No Shock Edition
The JK Wrangler 4-Link Long Arm Compound Suspension System, 4.5"/5.5", No Shock Edition is a weld-on Long Arm suspension system. The weld-on brackets for the upper front control arms provide the best pinion angle control for high-speed off-road wheeling.
MetalCloaks bolt-on DB3 rear set up, allowing optimal rear control arm geometry with the best clearance gives a perfect balance. Pinion angle and wheelbase change is least affected through the range of suspension movement with this suspension. High speed, rock crawl, expedition, or daily driver; for taller lift heights this may be the ultimate system.
Now made with DuPont™ Kevlar® fiber - the first suspension components manufactured with Kevlar® for industry leading durability.
Highlighted system features are:
- Front Weld on Brackets
- Rear Bolt on DB3
- High-Misalignment Vibration Dampening Duroflex™ Front Long Arms
- Front and Rear Durotrak™ Bushing equipped track bars
- Rear Coil Alignment Retainers
- True Dual Rate™ Coils
- Hi-Steer Kit
BTW, this system also out performs most long-arm kits in travel, articulation and flex with the smoothest and most predictable ride on or off-road with premium performance; this is as good as it gets.
Important Notes:
- Front and Rear driveshafts required.
- This suspension requires an Exhaust Loop Bypass Pipe on 2012+ JK's
Note: All lifted 2012+ JK's require exhaust spacers to clear front drive shaft at full droop. And we recommend you have a suspension specialist align your jeep once a MetalCloak Suspension is installed.

WHAT ARE TRUE DUAL RATE ™ COILS? MetalCloak JK Wrangler True Dual Rate™ Coils have one of the longest free length in the industry for greater articulation without sacrificing the OEM ride quality. Without the advantage of the Dual Rate Design, the required Spring Rate would be too low and "squishy" -- just loading your Jeep up with supplies would affect ride height and quality. |

| REAR COIL SPRING ALIGNMENT & RETAINER... | ||||||||||
 |
When lifting a Jeep, the pinion angle must be turned upwards to match the new drive-line angle.The changed pinion angle rolls the axle backwards and moves the factory spring plates, that once were horizonta, to an angled plane; this causes coil springs to bow and not seat properly. Correct the alignment for your rear coils.
Our system also features an in-coil retainer that attaches the coil spring to the coil bucket keeping you safer when at the extremes of articulation; this security feature also prevents rattling coils. |
