It fits stock to 6" lifts.

Apoc Toyota 4Runner adjustable trailing arms are a significant upgrade from stock; factory trailing arms work great with factory-sized tires, but once you go bigger, you need more robust and longer trailing arms to maintain correct pinion angles. Apoc Toyota 4Runner trailing arms are built to support proper suspension geometry to keep your trig handling like stock but better. When adding any lift to your Toyota 4Runner, you change your drive line angles which can create drive line vibrations and u joint failure. Big tires and big lifts look great, but don't sacrifice reliability, upgrade you control arms and drive with ease. Adjustable Controls arms are fully adjustable from stock all the way to 6" of lift, so if your just starting with a mild lift for now but upgrading later, these arms will suit your needs as you add more lift over time.

Control Arm lengths 

If you are upgrading from factory control arms make sure you set the length to the correct lift size to keep your steering geometry correct. The larger the lift the longer the control arms. Don't assume what your lift size is, if you are not sure contact the lift kit manufacture to verify your lift size. The Instructions will give you the measurements to set each control arm to match your lift, an alignment is recommended after install to insure all alignment angle are proper.
