Just got my 4Runner back from RSG Offroad for a new steering rack, but I also had a panhard bar correction kit welded on. Holy ****, that PCK might be the single biggest improvement I've made to the vehicle. After the lift, if I hit a bump or pothole the back end would jump and dance around due to the angle of the panhard bar. Sometimes, if I was going fast enough it felt like the back end was going skip sideways and cause me to lose control, especially on one expansion joint on a bridge on my way home from work. On my drive home from the shop with my panhard bar now parallel to the ground, this thing just floated over bumps and potholes on I-70 and I-25 at 75mph. Back end felt planted again and I didn't feel like I was going to die from the back end kicking out. If you have a 4Runner that's lifted, I cannot stress enough that you should add one of these to your rear suspension.
