Took a chance and ordered the Edelbrock IAS/VS-3 shocks from Shockwarehouse for my '07 2wd DC. I don't have a lot of miles on them yet but initial impression is WOW, what a difference!
Body roll and braking nose-dive really is reduced. Subjectively, body roll reduction is comparable to adding the TRD rear sway bar (which I have). Overall ride is much better and not too stiff at all; very comfortable. I haven't had them off-road yet but I drive almost 100% on-road anyway.
The pictures on Edelbrock and other web sites are generic; they are not exactly what the Tundra shocks look like. The pics don't do the silver finish justice - they really look good and the silver pretty much matches all body colors.
The fronts have two grooves machined into the body about 1.25" apart for a circlip which is how you adjust the ride height. The circlip is set into the "stock" position and I left it there. A nicely cast aluminum spring perch sits on this circlip. There's a machined groove on one side of the perch which must go downward to capture the circlip (this wasn't mentioned in the instructions, IIRC). Unfortunately, I didn't measure beforehand but the "stock" position seems about 3/4" higher than before.
Rears mount shaft-down (opposite the OEMs) and has a black boot with drainage provisions.
My SAP had KYBs on the rear and Tokikos on the front. The OEM rears were ok (I've had good luck with KYBs) but the front was pretty mushy and unpredectable, particularly over RR tracks, etc. I installed the Edelbrock rears a couple days earlier and didn't notice much difference over the KYBs until I installed the Edelbrock fronts.
I've had Bilsteins in the past and they were a little too soft for my tastes and Ranchos too stiff. I had a set of Monroe Reflex (on a Dakota) and they really helped handling similar to the IAS but they just didn't last and were about as stiff as Ranchos. The Reflex was what swayed me to try the Edelbrocks. However, I probably would have ordered the Bilsteins if the "1 free" offer included the '07+.
So, the Edelbrocks are a winner, IMHO. Nice ride - not too soft or stiff - with the benefits of the velocity-sensitive valving. Let's hope they last.
