I had to get my Radflo's serviced but I didn't have the time to pull them off and wait for the rebuild, so I just bought a brand new pair and had the take-offs sent to Radflo for a complete rebuild.
During the rebuild they replaced the spherical bearings and the shafts, so these should be nearly as good as new (they have only been out of the box for the photos)
I originally bought these from Metaltech (Radflo 2003-09 GX470 2.5" Extended Travel Coilovers -
Radflo 2003-09 GX470 2.5" Extended Travel Coilovers) and they are the perfect fit for the GX470 (or any 120 series - FJ, 4Runner). These are the extended travel versions that require aftermarket UCAs and they have 650 lb rated springs.
I am asking $775 obo for local (willing to meet within 100 mile radius of Charleston, though I could travel to Wilmington, NC or Greenville, SC) or $850 shipped in the packaging Radflo used to send them to me . These are currently about $1400 and have a 16 week lead time, so save some cash and wait time.
