    Creative ways to get height at rear axle?

    If you want to send me your struts, I can help you. I can measure the spring rate of the stock springs and replace them with something stiffer and adjustable. Another option would be to send your springs to http://www.coilsprings.com/ They can make you a custom spring to fit your application...

    Creative ways to get height at rear axle?

    He said this in another thread "I have a highlander hybrid converted to a camper, so it's at max payload." Sounds like he's overloaded and trying to raise the truck back up to a normal height. Installing generic air bags that go inside the spring like in the link I posted is probably his...

    Creative ways to get height at rear axle?

    Only if it matches your spring diameter which is doubtful. It's also not a great way to do what you want as those spacers can come out.

    Creative ways to get height at rear axle?

    It wouldn’t take much to figure out your spring rate and source some stiffer springs to use and convert your struts to adjustable coilovers. That or install airbags. Having it constantly riding on the bump stops sounds horrible. This is a job I’d do if you were nearby. I’ve done tons of custom...

    NPR 4wd conversion and camper build thread.

    I've completed the rear suspension at this point. Next I am redoing the ugly and scary front leaf spring mounts and installing a U bolt flip kit. I will also be incorporating the shock mounts into the upper U bolt plates and modifying the stock NPR shock towers to accept the rancho shocks. The...

    How Many Gears In A Transmission Is Too Many?

    I agree on the CVT potential. Seemingly they can't take much power but you would think a scaled up version would be fine.

    How Many Gears In A Transmission Is Too Many?

    As many as you need to stay in the torque for any given engine. I've driven a few newer autos with 6+ gears and it makes a difference. It's faster or more efficient as needed.

    NPR 4wd conversion and camper build thread.

    Rear shock mounts are mostly done. Final welding and additional bracing to the lower spring perches will tie it all together. I was forced to tilt the shocks over backwards because I will be limited on overhead space once the camper box is mounted. This thing won't be fast so I think I'll be...

    What's The Best Gasoline Engine Compression Ratio For RTW Travel?

    Depends on more than just compression ratio. Ignition timing, chamber design and temperature too.

    I'm not totally done with the lower perches actually. I am going to brace them up to the 4 link brackets. I agree, I would have liked the springs on top of the axle but I am limited on overhead height there as I am trying to keep the front top edge of the camper box about even with the cab...

    NPR 4wd conversion and camper build thread.

    Just finished the other upper perch and both lower perches. Shock mounts and panhard bar come next and I will have a complete rear suspension. With the springs I chose, 565lb/in, They compressed half an inch as they sit with pretty much nothing mounted on the back of the frame yet. Target ride...

    NPR 4wd conversion and camper build thread.

    I'll have around 10" of travel per corner. The shocks have a bit more travel than that. Planning on limiting straps in the back so the shocks don't become the limiters. I feel like that's a good amount of travel. In the future though I may go for more but for now I'm trying to keep it simple and...

    NPR 4wd conversion and camper build thread.

    I got one upper spring perch finished. Turned out good. I have a plan for the shock mounts but I want to be further along with the spring perches first so once I have the lowers done and springs in place I will finalize the shock mounts.

    Spring Mounted Flatbed?'s

    This is a well documented subject on this forum. I would just do the standard solid rear mount with sprung mounts forward of that. Just downsize a bit for your application maybe? My setup will be two subframes actually. One subframe for the camper to mount to in the back, mounted solid in the...

    Solar powered electric water heating using spare solar capacity?

    Beautiful work!! ^^^ As to the OP. If you are planning on diesel heat, you can easily have that system heat water too. But I guess if you plan on that much solar power, you should have plenty of excess power.

    NPR 4wd conversion and camper build thread.

    Thanks. I'm not worried about it. I could have built in more water capacity and battery space but I doubt I will ever need it. If some day I feel like I need more of either, the whole thing could become a water tank pretty easy and I can move the batteries.

    NPR 4wd conversion and camper build thread.

    I also finished the front subframe. The forward mounts are solid and bolt in where the stock transmission mount? crossmember bolted in. The rear mounts are sprung as you can see. The springs are about 200lb/in. The retaining bolts for the springs bolt into steel rods that are welded to the...
