Radflo Suspension Technologies Factory Tour + Sneak Peek @ My New Setup

[The4kbeast]

For those of you that don't venture outside of the 3G section, I visited Radflo's manufacturing facility earlier this month in Fountain Valley, CA and took some pictures I thought I'd share. I posted it in the general suspension section since they sell across generations.

That's a really clean setup. Those rear shocks look BEEFY!!! How's the ride quality? What price point are they? How much lift did you yield in front? 2.5"? 3"?

Beefy
Thanks, they are beefy. A 2.5" can holds about as much fluid as a 2.0" with an external reservoir. No external reservoir means I'm not sweating ripping it off. That said, I may get the upgrade when I get my first or second rebuild in the coming years.

Ride
Radflo used to run firmer setups based off their factory racing days, but the owner Glenn said that they softened their base tunings after they got more requests for the old Overland Warehouse tune. The new setup is much better than my old, stiff experimental Silverado Bilstein rear setup which was overly harsh, especially paired with OME 890's. Fronts feel great, and although they have less small bump compliance than the rear, some of the ride quality issues can be attributed to the spring preload I'm running. More on that below.

Compared to my brothers Icon setup, it rides nice enough on the road. The Icon setup is firmer than a typical Bilstein setup on both small bump and large hits thanks to its advanced valving. But there is a gap in mid-speed valving that I felt left too large of a gap between slow speed and high speed events on the Icons (granted, the rig I was in had suspended bump stops so the speeds achievable are much higher).

I'm trying to get the guys together to plan a wheeling trip for a true test in the off-highway.

MSRP
$1,750. 1995 ? 2002 Toyota 4Runner / Prado 90 2.5? Performance Suspension System

Ride height
I set them up for level frame height after everything settled, so I'll have to measure center hub to fender height. Before the springs settled in on a half tank of gas they were at 24". My sagged OE springs were 19.5... so figuring they were around 20.5" stock, I'm guessing with my adjustments I'll end up with around 3". I'll look and measure soon.

Nice! I been eyeing the radflo set for about a year, almost bought the high desert kit sonoran steel offered; however, the money went to getting the runner armored.
