80 Series Front Radius Arms

When the Toyota 80 series/Lexus LX450 was first released it was ahead of its time with the change to a coil spring suspension.  The handling and ride quality was dramatically improved in the vehicles stock configuration however when they are lifted things change dramatically. 

As the vehicle is lifted the suspension geometry changes and most noticeably the caster is lost.  The caster is what enables the steering wheel to naturally return back to center when turning and is also critical to ensure the vehicle tracks straight when going down the road.  When you eliminate the caster the vehicle has a tendency to wander all over the road and feel unsettled. 

The are a couple options to gain back the caster lost from lifting the vehicle, one involves replacing the radius arm bushings with an "eccentric" bushing kit and the other is a complete replacement radius arm set.  We chose to go the route of a complete replacement and fabricated new arms out of 1/4" and 3/16" chromoly.  Our radius arms allow the use of the OEM bushings which are known to be the most durable and provide the smoothest ride. 

All radius arms come as a pair and are powder coated gun metal gray.  You will need to purchase OEM bushings and the part numbers/quantities needed are listed below.
