Thanks, 70Turbobug! Not to worry. The drop blocks are solid aluminum blocks, not that extruded hollow stuff, and the u-bolts are heavy duty. A lot of the V8 S10 guys use these with no problems. The do recommend not going lower than a 2" drop to keep axle wrap at a minimum. These lowering blocks are u-bolts are very heavy duty. I doubt I'll ever have any problems.
