I've been running 3" djm aluminum blocks for years now...I believe they are straight(not angled) and have never had any vibration issues. I recently installed 3" Belltech lowering springs and planned on running them without the blocks, until I could get a mini notch....BUT someone stole my stock u-bolts, so I installed the 3" blocks to get it back on the road. I love the stance...Super LOW! But without the notch, frame slapping is no good on a daily driver. I've been thinking about getting 2" blocks (steel) to keep it low, but gain 1" of travel...But this is what I found (for cheap): http://www.ebay.com/itm/rear-axle-d...ash=item2eeca07731:g:baIAAOSw1x1UNCvY&vxp=mtr What's with the 3 degrees of pinion angle adjustment on a 2" block? Is that excessive? Do I need any pinion angle adjustment with 3" spings and 2" blocks? The driveline angle "looks" ok to me with the 3" blocks in there and seems to drive fine... Its the "angled" part that is tripping me out on a 2" block, lol. Experiences?
usually its the 3" and 4" blocks that have the taper to keep the rear end angle correct to the drive shaft...to avoid bindage. but i gues wouldnt hurt to have it on the 2" blockers too
