Four Wheel Camper Suspensions Mods

Hey everyone,

Looking for suspension recommendations from folks who have run heavy tundras.

I'm in the process of upgrading the suspension on my 2010 Tundra, which has a permanently installed Four Wheel Hawk. My current setup is stock with airbags in the rear. The ride is harsh, and I frequently crash into the bump stops on heavily potholed forest roads and normal roads. Small bump compliance and handling on washboards is also poor. Truck is underdamped and rings out after hitting bumps on highway (this may just due to long overdue shock replacement).

I’m planning to have Boise Spring Works fabricate a new rear leaf spring kit, but I’m undecided on which front/rear shock absorbers and front coils to run.

This is my daily street driver, I do not do any hardcore offroading, but spend a few weekends a month driving medium-quick speed (30-50mph) somewhat heavily potholed Washington forest road on the way to various off-the-beaten path outdoor destinations. My previous vehicle with a rough country lifted FJ Cruiser which handled shockingly better all around.

I’m currently considering the following shock options:

1. Bilstein 5100s (with new coils)
2. Eibach Stage 1 kit
3. OME
4. Bilstein 6112/5160 combo
5. Eibach Stage 2R kit (with remote reservoirs)
6. Some comination of the above with mix matched coils

I'm trying to achieve a 2.5” lift in the front, and my vehicle's loaded-down for a trip weight (where most offroad driving occurs) average around 3,450 lbs up front, 3,850 lbs rear, total 7,300 lbs. I'd rather not step up to the larger more expensive remote reservoir options listed above if 5100s/stage1/OME kit have done the trick for others in the past

Thanks for the help! I've searched lots of reviews out there, but I haven’t found much specific to heavier, loaded camper rigs. Any advice or recommendations would be greatly appreciated!

 

I'm rarely on here. But here is my set up I've ran for 2 years full time without any issues.
