GMF Bolt on Rear Shock Relocate for 2nd/3rd Gen, back in production

What length bolts did you use?

I think it also depends how good a job you did grinding everything off the axle, and the exact tolerance on the axle tube. Based on the difference in effort between the two sides on @TwistedTLM4 's truck I think we ran into a mixture of both.

 

Like bottom of frame to bottom of axle/ middle axle? Kinda confused lol.

 

You measure from the bottom of your frame (where the bump stop hits) to the bottom of the bump stop (worst case is the bump stop compresses completely flat). 9 and 3/4" in the above picture.

Then you set your lower tabs so that the shock has the same (9 and 3/4") of shaft showing. This will ensure that the bump stop does all the work limiting up-travel, and not your expensive new shocks.

I typically measure from metal to metal on both the truck and the shock, meaning any rubber bump stop in the shock will also be included in our 9 and 3/4" of travel. This puts the shocks at a little risk, since that rubber bumper could be compressed, but also buys me another 1/2" of down travel.

 

Hoops came in!

 

Do you measure with the suspension fully drooped or at ride height?

 

I always do ride height since it's not an exact 1:1 ratio. The closer to bump, the better.

 

Im getting like 4 2/16 inches from bottom of bump to bottom of frame at ride hight. That doesnt sound right to me lol.

 

Just depends on your bumps, lift, and leaf pack thickness. I just went and measured and I have 7" at ride height.

 

So just to clarify you have 7inches of shaft showing?

 

Ugh, gonna make me go back outside and work off this mcdonalds breakfast. One moment.

 

I have 6.25" shaft showing and 7" between bottom of bump and frame. I know it's setup correctly though because I broke down my leaf pack when I did it. Like I mentioned earlier, it's not an exact 1:1 ratio because math and whatever, plus every relocate is a hair different based on shock location and angle.

 

guess ill have to play with it lol. I hate doing maths

 

If you just set it to collapsed length + 4" then you'll be fine, that's erring on the side of caution. Worst case you lose a tiny bit of droop but you'll never need to worry about bottoming out your shocks.

 

Im sure that measurement will change again soon haha.....

 

4"-ish sounds about right for an OEM leaf pack. 7"-ish is abour fight for a setup with a shackle flip or a good aftermarket leaf pack.

The reason I like this method of setting the shocks is it works for full droop, full stuff, or anywhere in-between.

 

Ive got dakars with ubolt flip.

 

This is what I measured.

 

That's the right measurement. But your leaf pack looks pretty flat.

 

That’s Dakar’s for you. Mine used to be the same way.

 

Yup, only solution is links.
