Re: how much are offroad parts (rear,front ends)

First - it would be much easier to buy a set of matching axles from a donor truck to avoid problems with gearing, wheel bolt pattern, and brakes. If you get a matching set of axles you will need the following to properly lift.

1) Extend Brake lines and upgrade the master cylinder an/or prop valve for to application the axles came from (ie - 3/4 ton MC and prop valve if axles are from 3/4 ton - same for 1 ton)

2) Extend your parking break cables

3) Get drive-shafts lengthened and install appropriate conversion U-Joints since the attachment pinions will be different sizes.

4) Upgrade your steering by installing a brace for gearbox and adding either an extended pitman arm or a cross over steering set-up (High Steer is best choice).

5) Change the fluids and do necessary maintenance to donor axles.

6) Get the lift springs obviously - don't use bocks on the front if all you can find are 4" - you could also go custom springs which IMHO are far better since you can tailor make them to your intended application.

7) Get new U-Bolts <<DO NOT USE OLD ONES>>

If you don't get a matching set you will have to do all of the above and re-gear as appropriate since front and rear gear ratios must be the same, make sure the brake system is compatible with the different size brakes between the 2 axles, get wheel adapters since the bolt patterns are different, and deal with any small issues that may arise with the swap.

As for cost - to do it safely and properly the first time you could easily spend 1000 if you get a matched pair and even more if you don't since a re-gear will cost a few hundred as well.

Hope this helps, others will chime in if I left something out.
