 Alert | Thanks for the recs on which hi-lift to get in my other thread. Now I have a usage question…. I noticed a brief comment on the EP re something called a Jackstrap (http://www.rimrockmtn.com). This contraption is used to restrain the suspension allowing easier lifting with the Hi-Lift. The concept seems simple enough but I’m wondering if this is common practice for experienced off roaders and if there are other ways to accomplish the same task. In my mind, it would seem that anything that can help reduce the overall height of a lift would be safer/better. Any thoughts, common practices, tools/materials needed, how-tos, processes, etc.would be much appreciated? d | | | |

Alert | | using one would be handy when you have a lot of travel. I've been thinking of throwing a simple ratchet strap in for such an occassion. | |

Alert | | OK, so how is this done? i.e. what parts are being restrained, where are they, and how strong does the strap need to be? The EP comment suggested using a chain, but didn't elaborate. | | | |

Alert | A chain would be annoying. A ratchet strap that can hold 1000lbs would be more than enough, maybe too much. 700lbs? Loop it around the axle and frame. tighten (you're not trying to pull the wheel up, just keep it in place) and then jack the truck. No need for anything fancy.
maybe they suggested chain for the metal cutting the strap? | |

Alert | You want to hold the axle so it doesn't drop away from the frame. Take a look at possible attachment points, and consider how accessible they would be if your truck is axle deep in mud. Off the top of my head, the upper and lower spring perch are probably a good option.
I'm thinking a few feet of chain with one hook. Loop it around, hook it as tight as possible, then jack away. You could use your tree strap wrapped several times, too. | |

Which pic? I'd love to see the specific issue that you are trying to solve. And, yes, a ratchet strap could be used to secure the suspension travel. | |

Then you can't change the tire once it is in the air.

Alert | Michael, Dan's avatar, I meant. The Defender wheels don't have the holes in them that let the lift-mate work.
The specific issue he's trying to fix is having to lift the truck higher (more dangerous) than it needs to be to either change a tire or get a sand mat under something spinning in the mud. | |

Alert | Wouldn't an exhaust jack (air bag) be better for the specific situation? I have seen them used and they are amazing, but still another thing to carry... The guy lifted the rear axle, pushed it over the obstacle rolling off the air bag, and drove off.
Not sure I accomplished anything here, but excited to hear the response as to which is better in the situation... | |

Alert | From the Jackstrap FAQ:
"The Jackstrap can be fitted on virtually any 4 wheel drive vehicle but you must be sure not to exceed 5,000 lb. total vehicle weight."
Looks like we are SOL (at least the non-jeepers). | |

Alert | The vehicle weight really doesn't matter. It's the weight of what you're lifting, in this case, the axle so it shouldn't be a problem.
Todd, the bags are a pain to get under an axle. I've tried it and it's not easy and not as safe as a jack on the side. | |

Alert | So, the FAQ entry is there for no reason? I think it is a poorly worded way to say that their staps are supposed to work at up to the projected axle load of a 5000GVW vehicle. They are designed for light jeeps, not heavy Landys.
Now the reality is they probably won't break. That said, I would be no where near adding risk to the oh so safe hi-lift jacking proceedure. | |
