Lock-N-Load Replacement Upper Arm for Radius Suspension - Jeep TJ/LJ Wrangler

The Lock-N-Load upper arm on its own - as a spare for an existing kit, or to add the locking function to a plain radius arm setup.

The Duroflex joint

A patented joint in vulcanised elastomer reinforced with DuPont Kevlar fibre. It allows more misalignment than factory rubber, self-centres, damps vibration - without the noise of spherical joints - is maintenance free, and is rebuildable.

Specification

• Lock-N-Load: 2 1/2" x .120" steel tubing
• Duroflex joints in vulcanised elastomer with DuPont Kevlar fibre
• Finish: Gold Zinc
• Fitment: Jeep TJ and LJ Wrangler 1997-2006

How to use it - this is not optional

The arm has two positions: locked for road driving and released for off-road use. The product has 7 reviews averaging 83%, and the lowest comes precisely from skipping that rule:

"Only good for slow driving. Driving with it unlocked gives my Jeep wheel shake at 40 mph that then turns into death wobble after hitting a bump." - 1/5. Manufacturer's reply: "You should not be driving this on the road with the Lock-N-Load arm unlocked. It needs to be locked for on road driving which is why you are having a shake at 40 mph."

We quote the exchange in full because it captures the system: the off-road gain costs one action before the trail and one after.

After installation: the manufacturer recommends a suspension specialist aligns the vehicle after any work on the suspension or steering.

Installation

Easy. 1-2 hours.

A note on vehicle age

TJs and LJs are now twenty to nearly thirty years old. Expect seized bolts and corroded frame threads when removing factory parts - soak the joints in penetrant beforehand and use anti-seize on reassembly. Several reviews of TJ parts are really about this rather than about the part.
