EXCLUSIVE TECHNOLOGY - THIS IS NOT YOUR TYPICAL LONG ARM
|
Yes, the Radius Arm is now better than ever!
Bolt-In Upgraded Lock-N-Load Front Control Arms:
- Fit perfectly into the existing RE Belly pan on TJ/LJ Wrangler and XJ models.
- Adds Duroflex "bind free" rubber bushings that are "squeak free" and do not get pounded out.
- Allows smooth up and down wheel travel while keeping the pinion angle in check.
- Provides unmatched on and off-road handling characteristics that are just unbeatable.
We have new technology that solves an old problem:
Old technology Radius Arms have a single major problem... BIND. This bind causes premature bushing wear and undue stresses on the axle brackets that also limits free travel.
To make a Radius Arm work properly we created the Solution... please read on. |
Radius Arms Featuring the Lock-N-Load |

|
MEET LOCK-N-LOADTM OUR PATENTED SOLUTION FOR RADIUS ARM BIND
|
The Lock-N-Load solves the problem of the inherent bind of Radius Arm systems.
When a solid axle articulates by dropping one wheel while raising the other, one side of the solid axle will rotate forward and the other side backwards; the short length fixed control arms on a radius suspension limits this and puts a tremendous strain on all the related components.
- Eliminates Radius Arm Bind
- Dual-Purpose Control Arm
- "Lock It" for Daily Driving
- "Load It" for Trail Articulation
- Built with Duroflex¯¯™ Joints
- Exclusive Patented (US Patent 9,174,504) Technology
- Articulate like a 3-Link, but with the safety of a 4-Link

THE 4-LINK REAR, PERFECTED |

|
MetalCloak properly engineered the rear 4-Link. The RE Bolt-In Upgrade kit includes lower rear control arms with the built in Dog-Leg feature for greater clearance.
Long rear control arms work great but they sure do drag and hang on obstacles; that's why we made our lower control arms with a high clearance bend to optimize the functionality.
Our design eliminated the typical unsteady "Long Arm Roll" felt on a lifted Jeep while cornering - and that's without running a rear sway bar!*
And bolts directly into your RE belly pan with no modification.
*sway bars are recommended in most cases. |
Lower Arms, Bent for Extreme Clearance |

DUROFLEX - BRINGING FLEXY BACK
The next step in our evolution of the Radius Arm Suspension is the Duroflex™ Joint (Patent Pending) -- the key to getting the greatest off the shelf flex & on the road ride quality in a TJ/LJ Wrangler suspension kit. Period.
