Got to drive a short but very eroded trail today. We drove it a year ago with the Dobinsons front springs and the rest stock. It is not a challenging trail but Subarus and most trucks will leave their bumpers on it.

We got the suspension to stretch very nicely. It worked extremely well with the vehicle staying flatter than I thought it would. We did lift a rear wheel once, but only barely, while descending a very eroded short hill.

The difference vs aftermarket springs on stock shocks was easily felt. Whereas I had 1.25" front lift before and the same now, my front travel had decreased to 2.75" whereas now I have the lift AND extra travel over stock WITHOUT aftermarket UCAs, just as advertised by Toyota back when they first introduced the Bilstein TRD. Similarly, the Icon rear shocks with Eibach 1" springs, increased the travel in the back nearly 1.5" (front is +0.75"). HUGE difference when driving eroded desert trails or rock crawling though we have not been back into rocks with the new suspension.

In addition, the springs kept the vehicle nicely suspended above all the undulations, no sudden drops and hits like those that can be experienced with a softer suspension.

So the 650lb springs work great around here. But for most states, the 6112 with 600lb springs would be better because of the plush, on-a-cloud like ride on road.
