Eibach vs. Geiser

[Nick@Apollo-Optics]

It squats pretty bad, also driving at night is a constant reminder that i am blinding everyone. I am currently using the Airlift 1000 bag with OEM but it really limits the capability of this truck with set of airbags when i am out offroading. looking to upgrade to a new set of spring so that i can still, to some extent, have the capability of this truck with increased load. Just been on the fence between the standard and HD version of Eibach for a bit now.

I would probably steer you in the direction of the HD springs then if you're already maxing out the stock springs.

Also, Timbren would be a solid option to look at to replace the air bags on your truck. They use a polymer bumper design to help support the load and mount outside of the spring using the OEM bump stops. Now, they will limit you a bit when off-roading, however, it's about a 20 minute install and removal so if you've got a few minutes to take them off before you hit the trails, they're a solid option.

Wanted to bump this to ask a few questions...

I've got some new wheels coming in that are zero offset and while I do love the way my 24 37pp sits I wouldn't mind either going 1" Eibach in the front or the 2.5" Eibach front and 1" Rear. Are there any issues with the new dual valve shocks doing springs? Part of me really wants that 2.5" up front with a zero offset 17" wheel and 37's. It just looks so mean but didn't know how it rode, handled, or anything else. Also if anybody suggested any add ons to help in how it handled and rode daily. I'm all for doing that as well.

I would like to the either the spacer or the 1" rears to reduce the squat when gear is in the back, would the shocks need to be recalibrated?

May I ask you more about the Timbren? Missed that you were a supplier on here for the Geiser. I already ordered rears to replace my Eibachs. I do not plan on jumping my Raptor. Using it for Overlanding and some daily driving. I know not the ideal model for my use, but who does not love the interior and looks of the Raptor. But anyway, I know I will still get some sag with the Geiser and 1000 lbs in the bed. I plan on installing the Airlift 1000 bags. Which concerns me as I have a feeling the bags will fail sooner than later due to design and constant load at 25/30 psi. So is the purpose of the Timbren to stay in contact top and bottom to help with sag? Or just a taller than factory bump stop that helps as the rear "bounces"? Not a lot information I can find on the Timbren.

Great question and they have two different options so that's why it's kind of confusing.

They have the SES (Suspension Enhancement System) kit which is for load enhancement and that's what stays in constant contact and acts as an air bag.

Then you have the ABS (Active Bump Stop) kit which is an improved version of the factory bump stop, but does not provide as much load support as the SES kit.
