Timbren's or Upper Stable-Loads

My Chevy carries a very heavy TC (AF 1140), much heavier than the EC 950. On GM products you can use the lower stable loads but no uppers. My springs never touch the upper bump stops, but truck rides great with no sway. I credit my great stability to Supersprings and a Helwig sway bar. I have air bags installed but never once used them. Wish I had the money back that I paid for them.

I love the timbrens on my F150... when it's loaded up with weight.

When it's completely empty with nothing they are still awesome.

When it has just enough weight to "pre load" the timbrens, ie my boat, they're pretty crappy. Way too harsh a ride.

Here was my progression, one at a time in order, a couple of months and a couple of trips apart:

1. Air bags
2. Upper Stable Loads
3. Rear Bilstein Shocks
4. Lower Stable Loads

and then finally:

Cabover shocks/struts.

Done and dialed in.

get rid of the lower stable loads and throw in upper overload stable loads. All of my trucks have them. Airbags are inboard of the frame which is not the best for tc purposes. 950 EC is a pretty light camper for a DRW so really stock you should be fine can't expect it to handle like a sports car..

I had a 2004 dodge 3500 DRW 4X4 W/ Okanagan db96 ,10`1`` w/ slide
just put supersprings on it , it had upper overloads so the supersprings went over them and worked in comb with the overloads , you could adjust them by the shackle type plates at the end of the suppersprings, loaded great , unloaded and unengaged a little harsher.
I kept my 99 2500 dodge diesel 4x4 and have had 4 campers on it , 2 northstar pop ups and a outfitter apex 9.5 and now a Lance 500 legand thats more twards the limit , I have air bags and upper overloads , the air bags suck the larger the camper , they just add pogo even at 10 lbs , I lowered the bumpstops on the over loads and that helps ,the truck sits level fine and rides ok , but still rolls a bit .
So I have decided my next move is to quit fooling around with add on stuff and just put the leafs on that will handle the weight without all the endgadging and unengadging that you have with multable spring packs w/ overloads
General Spring sells 4000lb 8 leaf spring packs that are progresive, no bottom overload, for 180.00 each direct bolt on , like what comes on cab &chas trucks .Ive been told you can remove 1 or 2 leafs if you want and end up at about 2850 each . My truck already rides ruff , I have d25 front coils and dual bilstens in front ,bilstens in rear. It might cause need of dental repair riding unloaded but I bet, or hope it rides well loaded

I have a 2012 Mega cab DRW with a Lance 881. Im at 4000lbs loaded and with a set of upper stable loads. Im almost level but could use a little help. I have no sway issues at all and still have the factory shocks.

I think Im going to run some air bags over the springs to give me an extra inch to the rear.

1. Upper StableLoads on rear half of spring with Energy Suspension bump stops on front half
2. Firestone Ride Right air bags
3. 19.5 tires and rims
4. Rancho RS9000XL shocks
5. Lower StableLoads

Why get rid of the lower StableLoads? Their website recommends starting with those first.

I spoke to Torklift, they suggested just putting the upper Stable Loads
on the front since the rears are already contacting.

The truck rides level now, I certainly don't want the upper units to lift the truck at all.

In my application, I could not agree with the advice to start with the lowers. I had almost three inches between the upper overload springs and the pads. By adding the taller upper StableLoads, I was able to engage the springs sooner with less rear sag. The only reason I added air bags and lower stable loads was due to my tongue weight. I could level out with the bags, but they were a little bouncey (even after heavier dampening shocks). Now the lower StableLoads get me close to level and the bags just soften up the ride even when my waste tanks (closer to rear) are full.
