Rancho Quick Lift Install - Help

Hello All,

I am looking for some guidance with installing the Rancho Quick Lift 1.75". I was able to easily take off both sides without any stuck bolts.

But now in trying to put in the new spring assembly it appears to be a bit too long to slide in the lower bolt. But looking at the old and new shocks, the new rancho ones are maybe 1/2" longer.

I can see some locking nuts with cotter pins, should I take that apart to get more droop from the lower control arm? Should I be taking apart the lower ball joint?

Everything I have seen so far with installing seems so simple. Not sure where I have gone wrong.

Thanks for any help, couldn't find a thread that talked about the Quick Lift being "Too Long"

 

I've done it both ways. Removed the lbj once and learned the 2nd time to put the bottle jack above the upper arm and force the lower arm down.

On another vehicle, we just had the fattest guy in the group stand on the lower arm and force it down while pulling up on the fender.

I'd make sure your part # are correct for your application before continuing.

Good luck.

 

You'll want to do a couple things.

Easiest way to get the shock aligned with the bolt hole is to put a bottle jack between fender and tire and crank it down a bit to get it to fit.

The other thing is go get it aligned. This will do a couple things, re-align the front wheels so they're is alignment at your new ride height, but it will also "reset" your rubber bushings so they are at rest (not being twisted) at your new ride height. The problem is going to be your upper control arm bushings. Since those don't get adjusted with an alignment (like the cam bolts for the lowers), you'll want to loosen that main bolt (that connects to the frame) so that your bushings will be at rest at the higher ride height.

Will the truck explode if you don't do that? No, but it'll likely make your rubber bushings wear out faster since they'll always be a little bit twisted at ride height.

If at some point you upgrade to poly bushings (top and bottom) you don't need to worry about this.

 

Thanks for the tips, Matic! For some reason, Rancho doesn't put the vehicle-specific markings on the shocks. The largest stamped numbers just reference the universal strut they use.

The labels on the boxes were right though.

$216 RS999907 Suspension Strut and Coil Spring Assembly

RS999907 &

$208 RS999908 Quick Lift Loaded Strut

RS999908.

Rancho also does have Passenger/Driver Left/Right markings. It only fits one way though, with the adjustment valve facing the forward.

Thanks Justin for that Pro Tip, just ordered the Whiteline bushings with Amazon Prime. She's almost to 290,000 miles now. Haha.

Can't wait for that first turn out of the tire shop.
