What are the travel limits in the rear?
Rear suspension travel on KDSS 4runners is limited primarily on the passenger side. In some circumstances the stiff sway bar and fixed mounting point will reach their limit and bind up. In other situations the panhard bar will hit the axle. We have not seen a rear panhard bar that offers a substantial amount of additional rear travel.
KDSS 4Runners can use stock travel or extended travel rear shocks. Extended travel shocks will allow for more articulation on the driver side rear but will let the panhard to hit the axle in droop on the passenger side. The longest shock that will fit without contact is 25” from the upper shock mount to the center of the lower shock bolt. Plenty of KDSS equipped 4Runners have shocks measuring 26” or more without issue, they just don’t use the full shock travel.
