I was curious if you need to do a draglink flip for 3.5" lift? Right now I'm running 3" lift with 37s and am going up to 3.5" springs and 40s.

 

Many will say it is necessary, but I think it's a preference. See how much height you gain with the new coils, and get a feel for any changes in the way it handles, then decide from there.

At about 4" actual lift height, I did not have bumpsteer, but did have body roll from not having raised brackets at either end. I could definitely feel the difference when the brackets went on, but didn't really notice a change to the steering from the flip. (both brackets and the flip were done at the same time)

 

 

Agree, this is one of those things you can change the springs, see what actual lift you gain, and see how it is with the tires, THEN make that decision.

I personally had a decent bit of bump steer with 3.5" RK springs and about 3.75" of actual lift up front. I drove like that for quite a while....it wasn't terrible, but I noticed it. When I put a truss on, I opted for a raised TB bracket and went with a Yeti 26 no-drill flip. I immediately noticed a big difference IMO, and wished I had done it sooner.......but, I can see how everyone's experience differs.

 

Did you flip the dragline and not raise the axle bracket? It makes no sense you would get more bump steer from doing a flip unless something was not set up right. Flipping the drag link and raising the track bar bracket will flatten the links and improve tracking, minimize axle shift during articulation, raises the roll center reducing body roll, and increase the potential articulation you have that can occur in binding of the TRE's. Only drawbacks are cost (around $300) and the need for 3-3.5" of extra bump stop but with 40" tires you are going to be running that much bump stop anyway.

 

You flipped your drag link, realized it drove like shit, and then raised your track bar? Just no dude. It's supposed to happen all together, or not at all.

 

OK, so when i do a 3.5 Inch lift, I should also get a drag link and raise my track bar or not do it at all?

 

Both, or neither. The idea is to keep those two bars parallel to each other, while lessening the steeper angles caused by the lift. If you only do one, then the bars are not parallel, and you 'cause' bumpsteer.

Flip:
Raise the axle end of the draglink to the top of the knuckle AND raise the axle end of the trackbar with a bracket (or as part of a truss).

Drop Pitman:
Lower frame end of draglink AND move the trackbar with a bracket.
