Timbrens

I put timbrens on my 2016 3500 drw Ram. So far so good. I’ve got at 19k 5er toyhauler and was having about an inch more squat than I wanted. Yes airbags would have done the trick and would been more versatile. However. I wanted a hands off solution which timbrens are. For an automatic airbag system with pump and install, you can easily go north of $700. The timbrens achieve the extra lift I was looking for and help stabilize side to side jarring. Just don’t assume they are going to solve a suspension problem. They are there to help an otherwise health suspension.

It’s important that they don’t sit more than about 1” off the axels or they won’t engage soon enough to be beneficial. Also, too close and you will have a rough time unloaded ... 1/2”-1” is correct for these ... on the ram 2500/3500 at least.

The factory shocks were replaced long ago. Must be getting about time to replace the Bilsteins. A project for next winter along with trailer shock replacement.

Im guessing you should have done it right and bought new rear leaf springs. I think you would be happier.

In lieu of that, get your old spring pack re arched. Springs don'r wear out' they straighten out after time but they can be rearched again.

Nothing wrong with Timbrens. I use and like them but IMO if the OPs truck is still running old factory **** blown out GM shocks, replace them first with a good set of Bilstein 4600 or 5100.

I used SumoSprings in the 1500# variety. No jarring at all and the load just sits on the overload springs. You might consider the SuperSprings also if you don't have overloads. They do work as spring packs do wear and flatten out. Another option is a full length add-a-leaf. Usually any good spring shop can make you one and supply all the needed u-bolts, pins, etc.

From my install instructions http://timbren.wpengine.netdna-cdn.com/wp-content/uploads/2017/08/DR3500CA.pdf

Clearance Instructions:
Rear SES Kits for Pick-Ups and Vans should have a 1/2" to 1-1/2" gap between the rubber spring and contact point when empty.
A partial load, or vehicle accessories will reduce or eliminate the gap.
Front SES kits are usually in full contact.
Medium and Heavy-Duty Trucks, Trailers and Motorhomes will be in constant contact, and have no gap.

based on personal experience I would install air bags over Timbrens. Much more versatility!

What you want is for it not to be touching unloaded, and not to be almost touching with a load you carry often. Either sitting on the Timbrens or about a 1” gap. Comfort problems arise when you transition from springs to Timbrens while driving.

I believe it's 1/2" for DRW and 1" for SRW.

Just installed them on my 2016 Ram DRW to eliminate squat. 2800# pin. Just completed 1200 mi trip. Very nice ride improvement on rough roads. I didn't need the spacers.

Who cares what your trailer weighs...or what the gross weight rating is.

What matters most is the pin weight.

May be a truck scale will shock you and find your pin weight is 3,000lbs or more. Then may be some rubber helpers like the Timbrens might help a little. But they are just "helpers". Kinda silly for these weights.

If I had a HD truck towing that amount with more sag than I like, I'd be looking at new springs or some real nice air bags.
