Suspension update time!
I've had my Dobinsons IMS lift for a bit over a year now and have been mostly happy with it. It certainly takes the big bounces waaaay better than OEM and the truck feels planted and stable even with a 2-3" lift. But it always felt a little stiff, though not overly so. I reached out to Dobsinsons and learned that they updated the valve stack on the IMS system shortly after I purchased my set to soften up the response. They were willing to revalve my set free of cost. The customer service of Dobinsons is really stellar and I didn't realize this benefit when purchasing this set originally, but I sure am happy that I went with them.
Freshly revalved shocks on the workbench with new bushings and stuff (I did pay for the new hardware, not a big deal)
While I had the suspension apart I took the opportunity to do some upgrades and maintenance
New OEM outer tie rod jam nuts, since my originals were nice and rounded from many years of alignments. I even splurged and grabbed a 27mm spanner wrench and a 28mm crows foot so that I don't have to use daggum adjustable wrenches on these parts anymore. A nice coating of anti-seize on the threads to pay it forward to future alignment techs that will round out these new nuts LOL
I also bought a set of
Snowbound rear shock skids / protectors to cover the bottom of the shock mounts and the front of the shocks. I really like this design and concept.
A little black rustoleum gloss, because I like to keep it simple
Unfortunately there was not enough clearance on the front to allow the 17mm socket to drive the bolt in straight, so I had to file & dremel a bit to get it to work out properly
I contacted the owner and he got back to me within the hour, stating that he had already revised the design to allow a bit more clearance.
The skids certainly look cool and don't hang down much.
One of the air lines to my Air Lift 1000 airbags (which I have enjoyed greatly, especially when I was running 99 coils on a stock height suspension) was leaking so I decided to remove the airbags while I had the suspension apart. On a recent trip where I was loaded about as much as the poor 3RZ could handle anyway I realized that the Dobinsons coils really don't need the help of the airbags. This is with the bags deflated
I left the lines in place in case I want to reinstall them or a set of longer bags for lifted coils. The original bags were not leaking after 5 years of use and abuse so props to Air Lift for that!
The LBJs also got an update thanks to [MENTION=636945]Spiker Engineering[/MENTION] 's great
research into the mechanics of the bolts. I decided to add the 01-02 dust boot for extra protection and upgrade to the black bolt-with-washer that provides higher and more consistent preload even at the spec'ed 37 ft-lb of install torque.
Back to the original purpose of the whole project: the revalved Dobinsons shocks. At this point all I've had the time to do it run it up and down the street and over some speed humps. From what I can tell the shocks are significantly softer and still take the whoops with class -- my passengers were amazed at the response when hitting the neighborhood bumps at 40 mph :scared:
Will report back once I've had more time urban offroading
