Yea, top mounted resi is the problem. I would assume you can get more out of a 3" coil over because the reservoir is a larger diameter, right? (more surface area for N2 pressure)The question should be how much valving in a resi out the top shock, diameter is not really a factor.
.015's on comp is the most I would run for a durable consistent set-up. You can run more than that buy cranking up the N2 pressure, but it's still going to cavitate and will eventually cook the oil and start hurting the seals and backing o-ring if your shock has one. How long all this tale depends on how hard you are pushing it. For a mall crawler that gets the occasional sweet jump, go for it. You want to run the B1k or run main at Barstow all day, you need to add another shock........
Now if you have something like the Bilstien ACV valve, you can get way more tricky, but I would not run those in the rear.
Well, yes, but it never really works out that way in reality.Yea, top mounted resi is the problem. I would assume you can get more out of a 3" coil over because the reservoir is a larger diameter, right? (more surface area for N2 pressure)
Yea, makes sense ..... and no kidding...the Blackhawks have HUGE resi's!! Like almost coffee can sized.Well, yes, but it never really works out that way in reality.
Say you went from 2.5's to 3.0's on a Tacoma. You would not be using the same shim stacks as the would be to much. The lighter stacks needed for the large piston would not cavitate as much.......
Now if you move up to a F150 that weights 6500#'s your going to need bigger stacks in those shocks and you cavitation problem is right back.
Also, piston to resi diameter is pretty even ratio regardless of size. Unless you get into Blackhawks.............
12x what though? Doubled up 15's?A total of 12 shims on compression in a 2.5” King Prerunner series shock with a big king race series resi. 350psi in that sucker and it would rip down sand highway! Which if anyone has been to Club Glam lately, they know that those whoops are pretty big. A compression adjuster woulda helped but it was out of budget, so we put foam shaft bumps on there We poor folk make do with what we got laying around!
