Coil Spring Insulators

[pedaltheglobe]

One of the previous owners of my truck used two 4 inch stacked blocks in the rear to lift the truck. Seems totally unsafe.

I'm replacing them with 5 inch blocks from Rough Country. They used lift coil springs and 3-4 inch lift coil spring insulators to lift the front.

To level out the truck I'm replacing the aftermarket coil spring insulators with a factory spec size. Does anyone know where I can source these? I have heard them called both insulators and isolators, but when I google them not a lot comes up. The only thing I found are "coil lift isolators" from Energy Suspension. I can't figure out if I can use these as a replacement or if they are to be used in conjunction with the factory isolators?

I would like to do the job this evening if anyone knows how I could source this part locally...
Your help is appreciated.

Look into the pmf blocks that have the u bolts running through them. Trevor has a great product made! I love mine.

Thanks. This helped in my research. I ended up going with the insulators from Energy Suspension.

Those blocks look really nice. I have never been totally confident in the standard lift blocks basically being held in position by a single tab. I may order the pmf blocks in the near future.
