Fabricating trailing arms for your Ultra4, rock bouncer, rock crawler, Jeep or trail rig? TMR has you covered with our trailing arm link tabs! Get that long travel suspension needed to soak up the harshest off road conditions!

• Fits 2.0" & 2.5" coil over shocks, as well as 2.5" and 3.0" bypass shocks
• CNC laser cut from 3/16" steel
• 1/2" bolt hole fits all common shocks - coil overs, bypass shocks and more
• SOLD IN PAIRS
• Most commonly used for fabricating dual shock mount trailing arms, can also be used as a chassis side upper shock mount

TMR's proprietary Anti Wobble prevents your trailing arm from over rotating and breaking the shock eyes. They are the perfect joint for trailing arms that will come into contact with obstacles - ie: rocks, trees or other debris commonly encountered in an Ultra4 race buggy or rock bouncer.

Each Kit includes:

• 1 x weldable housing
• 2 x delrin bearings
• 2 x stainless steel misalignment spacers
• 1 x Spirolox retaining ring - offers 360 degree engagement and will not cause interference like cheaper snap rings with large "ears" 
• 1 x 1" bore heat treated stainless steel uniball (static load rating 90 000LB)
  
  2.625" mounting width is recommended when replacing a rod end with misalignment spacers, a Johnny Joint or other flex joint.
  
  4" mounting width is recommended when building custom chassis side mounts. The additional width aids in running a larger tube or fabricated trailing arm.

Anti Wobble's are also referred to as a wobble stopper or wobble stopper uniball for trailing arms.
