Max IV Springer

[Tinodesis]

I will want straps if my springer performs well enough to get any air under it. I suspect I'm going to be a bit too heavy.

I think they look fine and if it keeps anything from breaking I want it. Replacing/buying parts in multiples of eight is expensive.

I've jumped 2 stroke dirt bikes, 4-wheelers, even my old Toyota 4-runner. None of them had straps. Also, building an 8x8 Argo Springer and straps definitely are not needed on that either. I have put my entire body weight on the tire in its fully extended position, tire still spins, shock doesn't do anything, etc. If the shock is fully extended how would anything allow it to extend any further? To me it looks tacky.

I have ripped the whole shaft out of the shock, and ripped the whole upper brackets off of dune buggy plenty of times by not having limiting straps. The strap isnt as tacky as running around with a shock dangling all over.

After re-reading this it sounds like I may be a bit aggressive but I am really just saying what I have learned. So no offense ego.

They basically will prevent over traveling the shock. When you hit hard it springs back hard enough it slams the shock to maximum travel which is sort of like using a slide hammer on it. It will eventually ruin the shock.

Fully extending the shock drastically reduces its lifespan. The limiting straps stop the shock from forces that it shouldn't be seeing and keeps the suspension in the range that it was designed for.

Like Jeff said, they are used on all kinds of high performance off road applications. In rock crawling they are also used to limit the amount of articulation that the suspension provides.

As for the looks, I don't see how they look tacky.

Whipper has been at this for a long time and I don't think he would put limiting straps on there if they were just for cosmetics. As Lewis said, when you air the machine out you don't want the suspension slamming when all 6 tires are off the ground. If I had a vehicle with 6 shocks, I'd want to take as good care of the suspension components as possible.

I having driven these machines, think i understand and not speaking for Whipper. This prevents the shock from extending completely(Slamming to complete extension). Which with any cylinder that is a bad thing. This limits the travel to prevent damage. This is my thought on the way they work. Whipper and gang use these from what i understand on the sandrails and such. This design works. No one says you have to use it, it is just the way he designed it. I personally like the concept. Remembering that shocks are expensive but manufactures sell them so they don't mind you breaking them. Whipper's machines have 6, yours will have 8. Just my 2 cents.

Those are limiting straps. They use them on Baja racers, monster trucks, pre-runners, rock crawlers, etc, etc. They keep the shocks and drive components from over extending.

Very cool! One question; Whats up with the straps connected to the A-arms?

Awesome!

Looks great Whipper!

Everything fits so nice and compact I'm just a bit envious.

Great video! I absolutely loved watching the IV come together in the matter of only a few minutes. I can't wait to hear that new motor fire up too....the anticipation is growing. Excellent work!

I miss 2 days of the board and this happens. Whipper, I have a few work furlough days at the end of next week and owe you a good day of labor... if you need any help, I'm willing to drive 6 hrs (and maybe get a ride in the beast/lizard?) Wonder how it would run with a polaris liquid cooled 440? I really need to save for one of these.

VERY NICE! GREAT SUCCESS! HIGH FIVE!
Amazing Work, once again!

Whipper and crew have really outdone themselves on this monster.. then the 60 hp engine is another dose of testerone.. never mind the HP, the torque is gonna be impessive.
