I am posting this here as there are more views here than in the suspension/chassis section, mods if that's not cool kick me to the other category.
Okay, I was out to find a set of springs that would lower the back of my Tremor (I know, be nice, I have a bad back and need the tailgate lower for loading a heavy ebike)
I found in looking at global ranger pics that they look more level than the US models, so I purchased a set from the UK, they were pretty cheap and shipping was even cheaper.
They are a 5 leaf spring (Tremor has 4 leafs) they are quite different than the Tremor springs, the UK lower leafs are longer, and all the UK leafs are thinner, 1-2mm per leaf, I know that longer lower leafs help with axle wrap up, which should help dial out driveline vibrations.
So from a design standpoint, which one should be softer? or what would be the differences in spring characteristics between the two designs?
From the seat of the pants, the UK spring is softer over bumps, especially speed bumps, it's softer than the front, but I'm not sure on the highway high speed bumps, expansion joints and such, may be firmer there, it feels really good in and out of driveways, less rocking than the Tremor springs.
I don't know how the off road performance is on either spring unfortunately. (waiting for the rock guard to be laid on the truck)
I did take out the 5th leaf, that did lower the back, but only 1/2 inch, (tailgate 1") so my effort was a failure, so now I will get a pair de-arced a couple of inches.
It is easy to change springs, but not easy enough to do back to back comparisons, so I thought I would ask if anyone really knew leaf spring design and would chime in.
I will probably send out the UK springs for de-arcing and reinstall the Tremor which give me a better chance to compare the two.
The pics are not great, but notice how different they are, look at the 4th leaf, the UK one is really curved downward. for identification UK spring has the longer bottom (4th) spring.
If anybody wants some; https://www.ebay.com/itm/114729135896 they have 20+ sets and are very cool to deal with.
Not to mention how stupid cheap shipping is!!
