Keeping it level while towing - Airbags; Timbrens or new springs? (1 Viewer)

[visioncasting]

'18 LC - pretty stock except for the front coil spacer to level it out and 285x65x18 AT tires. LC sits nice and level unloaded; great looking stance. But I've upgraded my boat (Robalo 246 Cayman ~ 4000lbs; unsure of tongue weight - its on order and about 1 month out still) and expect once hitched it'll be too 'squatty' on the highway for my occasional long tows (300miles to the coast).

I'm considering:

• Firestone airbags - would like an auto leveling system or at least remote fill system if I go this route -OR-
• Timbren SES - seem like a DIY easy solution but will they work with the leveling spacer already upfront? -OR-
• Upgraded springs - but which ones? I don't want a harsh highway ride and don't want the front rake to return

So, given that I don't want to re-introduce front rake now that she's level and I also don't want to impact the highway ride unloaded (99% of my driving), what do you recommend? Anyone have experience?

TIA!

Have you got a list of parts you used for this? Did you install yourself or take to a shop?

Did it myself.

I’ve done lots of various projects on cars etc. but this was the first time doing wiring install.
First time doing suspension exchange.
First time working with airbags.

I like projects and especially with this one I’d like to know how to fix things if anything malfunctions out on the trail.

Besides the components mentioned above

SLEE bracket
Wiring equipment. Crimps and terminals.
Wire loom protection sleeves
Extra pneumatic air lines

It’s a big project but super rewarding and totally doable.

I’ll be doing a write up once I finalize and button things up.

Anyone have a tip on which Firestone airbags would be appropriate for a lc200 with a arb bp51 lift? I think that gives the lc about 2.5 inches of lift.

These are the ones I used with 2.5" lift. Just don't cut off as much of the factory rubber bump stop when doing the install to compensate for the lift.
