Lift Blocks

[bill49417]

Morning, after removing the snowplow from my J20, the frontend now sits higher than the rear. I plan on putting 2" lift blocks on the rear to put things back on an even keel so here's my question. Do I need to worry about the differential angle and install "wedge shaped" blocks or is 2" minimal and square blocks will work fine? Thanks and remember "Don't crush them, restore them"

My guess is that you'll be fine with no degree shims or degreed blocks. I'll bet that your springs have sagged enough that the lift will get you just back to factory height or little over.

I installed 3" springs on my '88 GW with no shims - and no problems. The net gain was 5.5". I can assume, if they where really 3" springs, that my factory springs had sagged 2.5"

If I had added 2" blocks, I would have been right about where the GW came off the assembly line... no shim needed.

You should be fine with a 2" block (0 Degree)...did you add leafs up up front to compensate for the plow? Is that why it's higher in the front? Just curious...

No, no add a leaf in the front. It has the 8400 spring pack on the front and rear. The spring packs are huge. Needless to say the ride is really rough. Already sits so high it just bearly fits in the garage. Now thats a truck!
