my rig has way too much leverage on my D30, i expect it to spit unit bearings pretty frequently.
Im running 37x14.50's on a 10" wheel with 1.5" spacer. im looking for 35x12.50's, but thats another story.
Theres alot to be said for name brand parts, make sure you've got high end ball joints. as long as you aren't jumping it you'll be fine.
