When lifting a vehicle it’s common for the factory upper control arm to no longer work, or no longer be able to achieve proper alignment specs. This is normally the case when lifting the 5th Generation 4Runner.
SPC has made an upper control arm that not only requires minimal maintenance, but also gives -/+ 2 degree of caster, and 0/+4 degree of camber. They are also designed around OEM ball joint and bushings, meaning these will last quite a long time. These allow for accurate alignments after lifting your 5th Generation 4Runner, as well as better handling and tire wear.
Both the ball joint and bushings are able to be greased in this kit, and have minimal exposure. This allows these upper control arms to last quite a long time, and prevent premature wear and tear.
The SPC upper control arms include both driver and passenger UCA’s.
