Great spacers!
And great deal at $200!
I've had a pair of those on my semi-float rear axle for the last four years.
There's people who swear that a quality pair of **aluminum** spacers are adequate....but jeez, for the total weights we put onto these built-out vans' axles, why screw around....the Fred Goeske steel ones are definitely the real deal.
(By the way, heavy as all get-out....I think a shipped package of two spacers was around 50 pounds.....)
Fred is an interesting character, btw....former National champion drag racer....naturally a real inclination for engineering/building bomb-proof vehicle components. Cool stuff.
