Lumping Springer Suspension w/ Revolver Shackles is like comparing Apples to a bulldozer. They are just not in the same group to compare.
Let's get something straight, Springer Suspension works!!! I am a living example of how this works, I wheel my junk almost every weekend during the wheeling season, and have had Zero problems with it. We wheel hard and a lot and to this day, I still like it very much. I have wheeled just about every trail in AZ, Moab, Farmington New Mexico, Las Cruces New Mexico, Parker AZ, any major trail system I have been on. I don't take the easy trails or the easy line either.
Don't let anyone tell you that Springer Suspension and Revolver Shackles are in the same class.
Just because I don't run Coilover suspension, don't discount the fact that I can't run nor should I say "Springer Suspension" can't be VERY TRAIL WORTHY.
I have yet to wheel the Hammers in CA, but I can promise you that it's got to be somewhat like some of the hard trails here in AZ, and I would have no problems wheeling the Hammers on my Springer.
You don't have to have the most up to date biggest hardcore wheeling components to wheel hard and not break or hit the hard trails, and anyone telling you differently is pointing you in the wrong direction.
I wheel with 35" tires too; does that mean I'm any less able? Ask anyone that wheel with us in AZ. They will be glad to comment on that fact.
I don't know anything about revolver shackles, but grouping Springer Suspension into the same category is totally not correct.
Just check out some of the Webshot or Group rides pictures, of some of the trails we have run. These pictures are real world rides on real world trails.
I'm not discounting the use of Coilovers or a fancier type of suspension, just pointing out a simple fact, which Springer Suspension works.
I also want to point out that this board sometimes is skewed towards the "Cool Stuff", or what certain vendors "Sell", but it's a proven fact that you don't have to have the "Cool Website Stuff That Everyone Talks About", to wheel on hard trails and have a good time. Dana 60's, Doublers, 42" tires, and Full Hydro steering are totally overrated and are expensive, to get started with, down the road as you understand what you want to do with your rig, buying this stuff is fine. If you have the $$$$ and want to have the "Cool stuff that everyone has" get this stuff, if you want to wheel and have fun with friends and others, find you way through trial and error, and find out what works.
There is a point when you have to have the "Cool very expensive stuff", but that after normally quite a few years of wheeling and understanding what you what to wheel and where you are going to wheel.
Just my opinion!
