Predeterminado Re: Mini proyecto Pathfinder R50 3.5

No puedo encontrar el post original, pero guarde una copia en mi PC.

Acá aparece todo explicado, al igual que el post de Ramdala..

Aspects of a subframe drop include:

-The subframe drop is 4 blocks. You can design it several ways, but honestly its simple. You are just making a rectangular spacer between the bolts and pushing the whole subframe down. Mine are 4" height.

-The engine requires 2 blocks the same height as the subframe drop blocks. These are also very simple design. Again just a spacer between bolts, rectangular with no angle.

-You also need to lift at the front suspension. However there are no longer struts available, so anything longer than AC coils will lead to severe topping out. So you will need spacers here too. These are NOT straight to keep the geometry right. If you are designing your own lift then you'll need some trial and error to make the angle right. My spacers are 2.5" and the rest of the lift comes from the AC coils. Most people have used 4" spacers plus AC or OME coils to achieve 5-6" total lift.

-You need to extend the steering shaft. I think most of us are using a honda U-joint with a spined shaft that matches the R50 shaft for the extension. I do not know if a straight extension would work, but I can confirm that this method does.

-The rear lift is much simpler than the front. You can use straight cylindrical blocks, longer coils, or both in combination to achieve the desired lift. I have 3" blocks and AC coils. There may be coils from another vehicle that fit, or you can order custom coils.

-You will want longer travel shocks in the rear

-You will need new bump stops in the rear and possibly limiting straps

-The stock panhard rod will be out of stock specs and force your rear axle towards the driver's side. The setup will work like this, but ideally you should make a drop bracket or a longer rod. Adjustable upper and lower control arms can be considered as well.

-You'll need longer brake lines front and rear

-You'll want to extend both differential breather tubes

-Your rear swaybar will be out of whack. I modified a stillen swaybar with longer links that can be disconnected with a single bolt. The front will still work if you want to keep it.

-The front skidplate will no longer work, you'll want a new one.

-Ideally you should add lateral bracing of the blocks up front. The SFD is kind of like putting your vehicle on stilts, and actions like laterally winching could twist your subframe. A solid skidplate will help.

-You'll need to adjust the routing of your front ABS line to prevent stretch

-If you are going with larger than 33" tires you will need to do a lot of trimming even after this lift. Of course you'll want to re-gear as well, especially if you have 4.3's.
