Rear Suspension Sag While Hauling/Towing

I was wondering what all is out there to counteract this rear suspension sag while hauling. I currently have the Fabtech 6" lift with the rear Fabtech shocks that comes with the kit. I offroad a lot so I am not sure that airbags would be a good idea. Maybe there is some adjustable shock that is made for this? Let me know what your thoughts are.

 

HD leaf springs.

 

^^^^

 

What do you have for rear suspension now? Block lift?

 

Depending upon how much room you have between the frame and the springs you may be able to get away with airbags and daystar cradles or go nuts and add a set of air shocks like guys are using on sua tundra's for towing. I think a couple tundra's have stowable king air shocks that unbolt and swing down to the axle where they can be mounted and charged for towing and then disconnected for normal driving.

 

Just the Fabtech block and add a leaf. OEM leafs are brand new from the Toyota recall replacement.

With that four wheeler in the bed and the bike on the hitch carrier I'd say that's 600+ pounds. Just sayin..,

 

what moto carrier is that?

 

Might wanna throw a tailgate reinforcement skin in while you're doing that work.

 

thats a lot of weight for this little truck. block is a no go, doesn't matter how new the factory spring are. you need full HD leaf pack for sure if this is something you do often

 

Get a new leaf pack. AAL is just a crutch for an already shitty leaf pack.

This is Icon RXT next to Stock TRD OR

 

Not digging into OP, but this thread/pic is why auto-leveling headlights should be mandatory on all trucks and SUVs. Can't count how many times I've been blinded by oncoming trucks that were loaded to the tits with weight and the headlights were shining straight into the sky as a result.

 

In case he doesn't get back to you. Here's what I've been using for at least 10 years. https://www.summitracing.com/parts/rrr-amc-400 (I didn't buy mine from Summit) Liked it so much I got one for my youngest son. I recently upgraded the ramp and added trailer lights. At almost 67 it was getting a little harder to push my 4 stroke up that short ramp. The 2 stroke isn't bad, but the new ramp makes life much easier.

 

Quick fix is to buy a light motorcycle or flat trailer with correct drop hitch good to go and no loading problems.

 

That is a visual cue that you're overloaded. As shown in the photo you don't have enough weight on the front axle in relation to the rear axle for safe driving. Your steering and braking are compromised right now. Modifying the suspension to make the truck sit level only hides the problem. You'd still be overloaded.

You need a bigger truck or a trailer to carry that much gear.

 

That moto carrier setup is only compounding the issue by applying a couple hundred pound load (dirt bike) to the end of a 3' cantilever arm from your hitch. Ditch the quad and throw the bike in the back of the truck.

 

Like burrito said.. the issue is exaggerated by the extension you're using to get the dirt bike waaay out on the arm past the tailgate.

Even with the proper leaf springs your handling at speed is going to be a recipe for disaster.. run over a bump/pothole at just the wrong time and you're going to lose the ability to steer (as the front wheels will have little downward weight when hitting a bump and bouncing just-wrong.)

Anyone know how much weight the cab will support? Can he air down the front tires (of the ATV) and use a couple aluminum ramps to get the 4 wheeler front wheels up on the cab? (He'd still want leaf spring upgrades or sumo springs imo.)

 

Hmmmm.....interesting.

You load the bed, hang stuff off the hitch and don't want the springs to compress.

Suggest to eliminate the springs and shocks, just weld a steel block between the axle and frame. It'll be cheaper than modifying the suspension that will still compress when loaded.

Springs are meant to compress when loaded. This provides a better ride and a more controllable vehicle.


FWIW, the stock leafs on my '06 will compress about 2" with a 1200 lb load in the bed. I wouldn't call it "sag".

Seriously, put the ATV on a small 4 x 8 trailer. There will be space for the bike too.

 

Thanks gentlemen. Both of those have 400lb weight ratings. I want to haul my DR650 which comes in around 325 or I bet just under 400 with fuel and armor. I might try that summit racing one out.
