Has anybody used these hollow rubber springs in place of the hard rubber bumpstops? I would assume it would smooth out the harsh bottoming out that our X's have.

It looks like they mount a little different than the original bumpstops and make contact with the axle...is that to gain the extra clearance needed for the increased height of these?

Thanx for any and all input, I'm getting tired of feeling like I'm riding in a buckboard....

 

Ken,

Timbrens are kinda like hard rubber air bags if you will. They sit with maybe 1" gap between the axle and timbren in an UNLOADED state.

When you drop a load on them and the leafs compress...the hard rubber begin to 'support' the Ex.

What they likely won't do is stop all of the buckboarding feeling as they will compress and uncompress because the leaf springs have not been made 'stiffer'...what the timbrens do is help to keep the leafs from compressing TOO MUCH.

Many go with the Timbrens that need to keep too much 'sagging'. But I'm not sure if they will reduce your buckboard feeling...

The rear springs on the Ex have a very low #/inch spring rate for the 7000# MONSTER axle under them...

If I remember right the Timbrens cost ~$150-180 for the set?...they 'help' I'm sure to keep the rear of the Ex from sagging too much...kinda like an air bag if you will...I guess...the install method...you are right they REPLACE the OEM overload stops...

I have been very vocal about my pleasurable towing experiences since installing the RAS on the rear of the Ex...I know the RAS improves the rear suspension in many different ways...Personally I would opt for the RAS over the Timbrens since i feel the RAS helps reduce axle warpage in addition to adding real spring capacity without making the ride too harsh...

I know you didn't ask about RAS...but...I think it will solve your buckboard issue...

Good luck,
joe.

 

Actually it's more the front of my X I have an issue with... I don't tow so rear compression isn't as issue. It's the 1" of front spring travel that 'jars' me.

I thought I remembered someone on here mentioning a softer bumpstop they used to cushion the impact when that huge 1" of travel hits on those hard rubber nubs...

I'm pretty sure a shackle kit, a V code swap or a lifted spring setup is in the cards down the road. I was just hoping for a cheaper alternative in the meantime so I don't lose half my coffee when I hit a small pothole.

 

Ken,

AH...now I understand what you mean...yeah...that HEAVY 7.3L up front...

I'm not sure if Timbrens makes FRONT ones or not.

I know even on my V10...there isn't a lot of room between the OEM stop and springs...

Sorry I mis-read your post about being up front...you could always lose ~600#'s of un-needed load by swapping that 7.3 for a 6.8!

joe.

 

As long as I can burn diesel in the V10...lol
