Upgrade rear suspension for camper?

Hey guys, I will soon be getting a Leer100XQ installed on my 2021 Platinum Crew Max.

Currently, I really like my truck's stance (slight rake) with the following components:

• Toytec 2.5 Series Front Aluma coilovers
• Toytect 2.0 aluma series IFP rear shocks
• Coachbuilder shackles (3”)
• Front differential drop

• Durobumps front/rear
• SPC UCAs
• Coachbuilder carrier bearing drop
• 295/70/18 Baja Boss tires on stock wheels with 1.5" spacers

I am worried about sag over time with just the stock leaf springs. The rest of the truck is essentially stock with minimal weight typically in bed besides future camper shell.

Would upgraded leaf springs be the best move to maintain the slight rake/prevent sag? RAS?

The truck mainly is on the highway or forest service/gravel roads...want to keep decent on road manners. No significant rock crawling planned

Picture of current set-up (haven't updated the build thread yet) for attention!



Appreciate any suggestions/pics!

 

I have and love RAS, supports the weak rear leafs, no harsh ride, greatly helps with squat while towing and hauling, great price (get the HD version), easy install. Lifts rear 1-1.5 depending on the setting disk used. I do not know if RAS can be used with lift shackles.

 

The topper is what, maybe 200 lbs? Maybe have a couple of your buddies stand in the back of your truck and see how much it drops, it might level at most.

It's gonna' take years to start sagging if you're not towing or hauling heavy pretty frequently. Maybe run it for awhile before spending money you may not need to. If it sags in 3, 5, 10 years then get a new spring pack.

I just sold my '00 (22 years old) Tundra 6 months ago, and it was just getting to where I was thinking about leaf spring replacement/upgrades, and I tow regularly.

Nice looking truck!

That having been said, Deaver makes some pretty nice spring packs!
