I hate to tell you this, but putting your Ford Ranger on stilts will not improve its ground clearance: the differential will still be the low point on the truck and that is where you get high-centered 99 times out of 99.
To the contrary, by raising the truck on blocks, you only raise the center of gravity which can send you rolling down a hill whenever you hit a lateral grade your truck once could handle.
The best advice is to keep it stock, maintain it professionally, and never compromise safety or reliability.
