Sounds like a lot of suggestions on aftermarket parts, some of which would probably sell 1 or 2 ever once price is completely set in stone. I'm pretty sure toast and incx idea is to produce a strong aftermarket of much needed wearing parts that are important first and for most. They would also like to make the cost affordable due to most montero owners being cheap...very cheap. Not a knock on you if your that guy, cause honestly we buy monteros because they are highly durable, comfortable to drive, and ... cheap.
The panhard rod/bar that toast and incorpx have made is STOUT. Durability and strength on this item is very important due to the fact it positions your axle to square your truck up. Also, this panhard rod has the tendency to get smacked around a bit by rocks (if that's how you roll) while 4 wheeling around and using the truck to do what they are built to do. I bent mine so bad it pulled the axle about 1" further to the passanger side. I also run 3" or 4" lift coils which also contributes to the angle it puts the panhard rod. As you lift your truck by doing a suspension lift it raises the frame upward and changes the angle on the panhard rod, and draws your axle further to the left (passanger side). This causes the truck to track funny on road, and create a little bit of a sway affect while changing lanes, finding groves in the road, or going over slight bumps. Makes it very noticeable at highway speeds.
If you do a suspension lift on your truck, you NEED to buy this panhard rod. This part not only aligns your truck to ride and track better, it will save on the stress to your lower trailing arm bushings. It also helps the slight drive line angle from the drive shaft. Even the smallest lift creates stress on your truck due to the position of the axle. Stop wearing your bushings out faster and putting your axle at a bad angle.
I have ran mine for about a week or so now. Truck rides so much better and my axle is damn near center.
