I have some Bell Tech spindles on my 74swb pick-up that's been my daily driver since '04.

I lowered the truck in '03. It saw limited milage (mostly shows or weekend stuff) & I had to replace the 245/45-18 Dunlops after 1yr. because of wear on the tires edge.

I took the truck back to the same guy just to dbl. check the alignment specs. The only issue I had after the original alignment was the steering wheel wasn't perfectly centered. We all know how annoying that is to gear-heads; other than that the truck drove straight. After about 9-months, it developed a pull to the right that grew increasingly worse as the tires developed wear patterns.

The alignment was still in spec other than the changes to the toe setting/s to correct for the off-centered steering wheel. The truck has been on the road since (daily use now) & is still using that second set of Dunlops.

My 'kit':
B.Tech 3" spindles + 1-coil removed from the stock V8 springs
Western Chassis rear leaf flip-kit & lower shock bracket extensions
B.Tech dropped shackles

I say get the alignment verified.
