New Dobinsons VT series dual rate coils

[baldilocks]

My wife asks me the same thing all the time.

Mine gave up about five years ago. Yesterday I ordered new 37’sand 4 trail ready beadlock wheels in bronze. $4200 I really need this stuff

2020 and 2021 in this industry and many more have been the years of it being harder to get product than to sell it. That was mentioned as a factor in the change as stated by them.

I’ve got a set of lightly used 146 / 147’s that have been waiting for me to add weight, Shortbus and winch order went in today so I better hit the deck for some shocks to go with these. It never ends…

For the new version, is the diameter (gauge) of the coil wire tapered?

There are no visual cues to say so. I’d stick with the legacy tapered coils.

I have a weird feeling they cut production on the OG tapered coils because they were a pain to get consistent. I’m running the 2.5” tapered coils and I get a solid 4” with the 80 weighing 6300 lbs. I talked to one of the dobinsons reps for a month and sent him every measurement I could on the springs. He ended up telling me that the lift height I was getting was completely different than what the spring calculator predicted it should be. It seems like these spring can give anywhere from 2” to 4” of lift and despite the weight of the 80. They’re amazing springs despite getting random lift heights, I wouldn’t trade mine for anything else. But I bet they got tired of the complaints, more complicated production, and the cost

I’ve read your thread and hope I dont suffer the same fate, I’m hoping to hit somewhere near 35” on all four corners. I’ll have front bumper and winch, sliders and rear bumper double swung with a 35” spare out back, not sure what she will weigh so we‘ll see. The springs were a bargain used so I went for them.

The springs still work great! I just wish I went with the 6” shocks. I’m sure you’ll be stoked with them! And is that 35” from the ground to the flare? Usually it’s measure from the hub to the flare, mines a about 24”.

One too many beers on my wife’s 60th, let’s try 23” hub to fender

Hahaha That the height I wish I had! And congratulations

Fresh 3.5" VT coils on the front. 27" hub to fender (no flares). I need to check again but 27" was on the night I installed them.

Wire diameter is consistent end to end.

Man, that's what ... 5.5" of lift? Seem to remember my stock center of hub to fender (flare) was 21.5".

Well to through a wrench in the lift height my 146VT 2.5" coils I have received 2" of lift & then when I swapped sides to get rid of the coil shim they sit at 21.5" bottom of fender... So I added the 25mm spacer in there to reach a 2.5" lift.... go figure.

Installing my "new model" VTs today - will post up numbers tonight.

That would make sense relative to the manufacturing efficiencies comment. Ensuring the taper is created to spec and positioned correctly within the coil definitely adds some complexity to the manufacturing process. Likely slows output versus a more traditional design as well. I’ve wondered how much difference it really made anyway. It would be interesting to see the actual deflection curves of tapered vs variable vs linear.

It’s just a spring ...

But it's a bougie spring.

And it’s MUD 80’s forum. I’d expect no less lol

For all its foolishness, mud is probably the best forum in its category.

Simplistically so…until it doesn’t perform as desired.
