When you put on a lift kit, don't you need a longer drive shaft?

When you put on a lift kit, don't you need a longer drive shaft?

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?

You've got the right logic.... However - each driveshaft has a slip yoke which allows the driveshaft to move inward/outward depending on suspension travel. In most cases - that slip yoke has plenty of distance travel within it to compensate for mild/medium lifts. So it's not something that you need to be concerned with (for the most part).

In higher lifts - it all depends - you'll experience driveline angle problems before you experience 'length issues'.

If you have a high lift and a lot of suspension travel - you'll probably need a longer driveshaft .....however....it's the SLIP YOKE distance that's most important. The more distance in your slip yoke - the more that driveshaft can expand.

If you've ever heard about Revolver Shackles.....they allow your suspension to travel A LOT and having an extended slip yoke is a necessity when running them or else your driveshaft will pull outta the splines at the slip yoke.

+1, With the mild lifts that we can put on our trucks, the drive shaft only grows about a 1/2". Your thinking is correct but, the drive shaft and the truck run a such parallel angles the you don't see much growth.

A 3" lift only stretches the slip yoke about 1/4". Most slip yokes can travel several inches in and out. Lots of room for movement up or down.

Thank you community members and your knowledge.

I tried to ask some people at work, even those who had their trucks lifted, and they didn't know the answer.

These are the strange things that I lose sleep over. I wouldn't be able to comfortably be settled with any modification such as this unless I had this burning question answered.

My neuroses revealed.

I feel your pain...I've always had the urge *to know* that kinda stuff.....

Don't ever lose that way of thinking - cuz that'll be the difference between doing something RIGHT (knowing what's involved) versus doing something half-azzed.

Good Luck with your modification plans! Have fun with it!

Boo for Revtek.

Check out Donahoe Racing, Camburg, or SwayAway. Here's a good place to shop. http://www.wheelersoffroad.com/05uptacoma.htm
