Hey guys as some may know I bought my 08 access cab 4x4 used. In speaking to the Previous Owner (PO), The way he did his lift is got new adjustable icon coilovers for the front (stock UCA etc) and they are supposedly set at about 2.5"
He carried a lot of tools for his job plus did expedition, so when lifting the rear suspension, he did an AAL type thing so the rear is now 5 regular springs plus the overload, so a 6 spring pack. He also put in firestone airbags for when hauling cords of wood to his place etc. After adding the leafs he had a suspension shop 'custom arch' them to make sure they are level with the front, however that works.
Anyways, the airbags are a great idea because they add very little stiffness when at 5psi but can add thousands of pounds of load carrying for the rear suspension.
The fat spring pack is another issue. Going over any kind of bumps in town, or god forbid speed bumps, jerks the rear hard. Feels like a hard-tail back there. This is at 5psi in the air bags so pretty sure they are not the issue.
Here are some pics of the rear suspension.
I'm so damn happy with the front. I've gone over washboard at 70mph and the front felt planted and in-control. Big potholes got soaked up almost like they weren't there.
Prob thanks to the great icon coilovers.
The rear though just feels like I said, hard as a rock.
Anyways, any ideas of what I should do ? I'd like to get some nice controllable rear end that will soak up some bumps/potholes, and when I need load carrying, I'll pump the airbags.
Should I sell this leaf pack and coil (good luck for the coil, it has a lot of surface rust on it..used to be white I believe haha) then use the proceeds to get a TSB leaf pack (our stock pack here in canada) and some Icon RR shocks ?
Or is there a less drastic way of keeping the proper height but losing stiffness?
Thanks for your help everyone, this site kicks ass.
