"Big Bolt" Double Adjustable Aluminum Control Arms, Upper Front, Pair - Jeep TJ/LJ Wrangler

A pair of upper front aluminum control arms on Duroflex joints, adjustable at both ends. Replacing the factory rubber-bushed arms buys both more articulation and the ability to set the geometry correctly after a lift.

Double adjustable aluminum arms

A 1.5" hex aircraft aluminum body is lighter than steel at comparable stiffness - unsprung mass matters more in suspension than body mass. Double adjustable means threads at both ends: length can be changed without removing the arm from the vehicle, which saves a great deal of time when setting caster and centring the axle.

What "Big Bolt" means

The Big Bolt version has an enlarged mounting bolt hole - it is intended for axles whose factory bore has been drilled out, or for conversions using larger bolts. If your axle is in factory condition, the standard version is the right one.

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

• Bodies: 1 1/2" hex aircraft aluminum
• Duroflex joints in vulcanised elastomer with DuPont Kevlar fibre
• Double adjustable
• Finish: gold zinc steel, raw aluminum
• Fitment: Jeep TJ and LJ Wrangler 1997-2006, XJ Cherokee 1984-2001

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

Installation

Easy to moderate. 1-2 hours. An alignment is required afterwards.

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.
