UCA’s and Eibach Pro-truck 3.5 lift?

Bajones9181 · Jan 18, 2019

I know that going much over 2.5 up front on a stock setup can start to present some geometry issues. I will be installing the Eibach pro-truck lift on my 2013 sport soon. This kit has the 2.75 lift and a 3.5 ‘heavy bumper’ setting as well. If I combine geometry corrected UCA’s such and the Zone’s with the 3.5 lift will my geometry be ok or are there still some geometry concerns at that height even when combined with the UCA?

CV angles might be a bit much I would think ...

The UCA will correct the upper ball joint angle, but your tie rods and CV axle angles "might" be a little extreme. You could always try it, it would be no worse than the 3.5" ready lift they sell.

I think that’s the reason most coilover shocks don’t recommend are 2.5” max. They don’t wanna be liable for damages to drivetrain.

Both of these posts are exactly my thoughts. You are still going to have CV angles that will be extreme. Exactly why coil overs dont offer that much lift. extreme CV angles and off roading will cause premature failure. street driving and extreme angles will also cause issues eventually.

Thanks for the feedback. That was my concern. Definitely want to stay away from as many issues as possible so will stick with the 2.75 setting.

You could always try it, it’s only an additional 3/4” and worse case you just adjust it down. You will need the rear coils or a rear spacer to bring that up too.

There’s a member here with Bilsteins at 2.75 and a 2” spacer (see thread for CV pics)

If you need to level out the rear of your truck, there’s a guy the has new Icon coil springs for sale! :wave:

Give it a try, only one way to know for sure.
