Timbren upgrades

Anyone running timbrens on the front of their 22k chassis? How’s the ride?

Installation is simple, but at 5600lbs of support, I think they will not do much for this leaf spring ride given their rigidity.

I wish they had a softer set, like sumo’s….

Speaking of sumo’s, anyone know why their front set for these chassis’ isn’t a straight bump stop replacement like most others? Why the additional framing and $600+cost?

I believe the front set is two separate pieces to allow for more suspension articulation. I have sumo's front and rear on my 20,500lb chassis and they make a big difference.

Correct. Two piece. I also have Sumo's just on the front of our 22K chassis and they made a HUGE difference. Easy install too.

Huge difference how? I'm always looking for improvements to the suspension/ride quality.

The "slam jams" on the highway are not nearly as intense. Much smoother ride and less front end sway/roll.

IMHO! Either of the above mentioned items have limitations. They are not very forgiving. Once they compress that's it. The ride gets harsher because there's no more room to compress. In fact they almost become a bump stop or jounce bumper after they compress.

I've had Sumo's on the front and took them off. My local friend has them on all 4 wheels and likes them. He is on the 18-K chassis but his unit is about 3' shorter than ours so he notices better sway control. Yes they will improve the sway but not sure how much they add to the ride quality once they are compressed.

I'm sure most of you have read about adding air bags and ping tanks. We've had 3 who have done it had decent or good results. When the air bag hits a bump the 1/2 gallon air tank allows the air to compress and is stored in the ping tank thereby making the ride more absorbent, smoother and less harsh.

My install is done and after a local 35 to 40 mile ride myself and a firend both agreed the ride was much improved. We'll be taking a 250-280 mile (1-way) drive in a few weeks and it will be over mostly 2-lane winding hilly roads.

It's understandably only a few of us have completed this type of install. The jury is not in yet so we'll see.

I agree with TeJay and most others about the ride which is why I didn't pursue the Timbrens on the front. But I did put them on the back because we lean passenger side and the Timbrens are really good at helping with that. Plus I'm lazier than the guys who do airbags.

But I didn't want to put Sumos (don't like the idea or function of a split Sumo) or Timbrens (essentially putting on bricks) on the front because of the ride. I know they will keep me more level and help with sway, but that banging harshness wasn't going to sit well with 'she who must be obeyed'. So.........

This is probably going to incur the wrath of all those experts out there, but it's ok. It's my ride. I found that Sumo's for a Ranger p/u fit the jounce stops holes on the front of my 22k chassis (8k FGAWR). So I ordered ones that only support 1000lbs. They hang like they would on a p/u..... slightly above the jounce plate and only come into play when the axle comes up. And since they are the 1000 pounders, they give more and hopefully won't be as bad as I think the Timbrens would be. Not quite full Sumo's or airbags, but just a little extra to help with the sway, level, and ride.

Not sure about how much the front axle moves side to side, but the jounce plates extend outside of the spring pack and the blue 1000lb Sumos are fairly flexible. They might get torn up (I doubt it) but for me it's worth a try. At worst, they become jounce bumpers. At best, nicer ride with SOME support for sway. I haven't driven it yet to see the impact of the placement or its effect.

PS...if this turns into c*ap, TeJay, I'll make you an offer on your Sumo's.
