Aeon Rubber

[westyss]

I installed timbrens on the front to try to get a better ride, and the ride was some what improved as far as a bit more absorbsion by the timbrens, but, not much. My concensus is that the travel is limited overall in the front so that the timbrens compress a certain amount to slowly absorb the shock but the limited travel available in front will not improve, that has a set limit that can only get better by a lift. Once the lift is in then the timbren could compress progressively, but as it stands in a stock truck , the front is not going to get much better. I think I said this before, but I would save my money for a better suspension, hind sight being 20/20, that being said, anyone want to buy some timbrens??

Note: Suspension guy said the same thing, just not enough travel distance available with stock suspension.

I agree that there is inadequate travel in the OE suspension. However, I can't justify the $$ for a complete suspension upgrade in the my truck. The front Timbrens did improve the ride quality significantly, mostly by eliminating the ultra hard bump stop which comes into play all the time with the short travel. Not sure the rears will make that noticeable a difference but those bump stops are just as hard so they will make some difference.
I'm curious as to what more engineering inclined people than myself make of the load being transferred from the 'helper' or 'overload' spring to the Timbrens. Significant or not??

Here's how the fitting went,
At first the holes were too small for the bolts supplied


So then I had to drill the bastard out, which isn't an issue with the drill resharpened for battery drill cutting speed.


then the bolt went through with about .25 mm tolerance, nice...


As you can see, not much chance of it working until it's loaded...


Steers were easier with a 3/4" Impact gun, loosened the U bolts and removed the bumpstop.


Slide the new Aeons in and retighten the U bolts


Compare the Old V's New, You can see the difference the progressive Aeon has over the std. bump stop. And I agree with Defenderbeam (and his dog, which you would never want to argue with!!!) the steers show an immediate improvement, as I'm sure the rears will.

In those pictures, your rear Timbrens look much smaller than mine. Maybe it is because you are unloaded and the perspective of the camera but I had to jack up my truck by the frame quite a bit to get the Timbrens in place and they barely squeezed in between the shock and the frame. The rears on mine are far bigger than the fronts. This is with the camper on the truck. They are about 1-2" taller than the OE bump stops. Is that the case on yours?

[kerry]

I thought of another related question. How does the fact that the Timbrens cause the truck to ride higher effect the brake proportioning valve/system? I assume the higher ride means it thinks the rear of the truck is lighter than it really is??

[kerry]

Took the first long trip this past weekend with the rear Timbrens installed. They do make a difference. They left me with the surprising impression that the truck actually has suspension. Definitely worth doing front and back although the results you get will probably depend on how the weight is distributed on your truck.

We fitted front and rears Aeons to our FG649 and took it for a test drive for 700kms on mainly dirt back roads towing a trailer the ride has improved heaps . There is no more jarring from bumps.

Have any of you who have been running with Aeon rubber front and/or rear for a while now got any recent comments about how they are going? Have they made a real difference? How are they wearing? Any unexpected issues or concerns about "knock on" effects elsewhere in the vehicle. Would you go down this path again?
Or any comments about: http://www.trelleborg.com/en/Automot.../Rubber-Tower/

Hi Rick,
Just do it, you wont regret it!!! They are still going strong on the tour bus.

Just finished at trip up and down I-76 in Colorado which I had done with no Timbrens, with just front Timbrens and now with front and rear Timbrens. I'd say the ride is improved between 20-25% with the Timbrens. Very subjective measure, I know, but the Timbrens take away the very rough jarring which occurs with the OE bump stops.

[DEFENDERBEAM]

I think the improvement is WELL worth the money
