Posting this here as well - I tried to re-install my once again rebuilt Radflo 2.5" coil overs today (second time in 6 years) and first off, the coils were not set to the same heights, they were never cleaned so the threads were a little gummed and difficult to adjust, and to top it all off - the $200 top hats that I had to replace because Radflo did crappy work on the first rebuild that required one hat to be torched off - were the wrong top hats, the bolts were over an inch off center from original. $550 later, this is the service from the Radflo recommended Canadian rebuild shop.
On top of this, someone from Radflo has been PM'ing me, only to question where I got their parts (the wrong ones at that and was ordered and shipped/installed by their recommended shop), and when I asked about their initial poor workmanship requiring the extra $200 in parts, well then there was no return responses. Between initial purchase and all the repairs, I am into these coil overs over $1500 in 6 years - complete junk in my eyes. The shop that rebuilt them said the oil smelled like swamp water but there were apparently no water leaks, even after rebuild the shocks were 'very stiff to cycle' - so expect more rebuild costs in the near future. Spend your money elsewhere.

I noticed my $500 Radflo preferred shop rebuild of my coils has resulted in my shocks leaking again after just 2 months. I called the shop yesterday to see if there was any warranty on the rebuild - nope. I asked if he could talk to Radflo and see if there is anything they may be willing to do to assist, we shall see what they say.
If I didn't have access to a shop, these Radflos would be costing over $2,500 already. As is, I am over $1,500 into them from my repair costs, let alone gas/minimal shop fees I do pay.
