I notice lift kit ads everywhere that install shocks, springs etc and lift your truck 2-4 inches.
When you do this, doesn't the length of the rear axle become farther from it's previous/stock location?
If it's further away, doesn't the vehicle need to have a longer driveshaft?
Just trying to understand the physics of it. My mind is saying, if you live the truck one mile high, for instance or 4 inches higher. The result is the same...
Longer distance from transmission to rear axle. So I never see these kits offering any driveshaft changes.
Or am I wrong about my logic?
