How does a driveshaft balancer work?
Balance Masters® are mounted at one end of the driveshaft approximately 1 to 6 inches from either end. This patented liquid metal (Quick Silver) technology, works by centrifugal force to help increase bearing life and reduce the running vibrations up to 50% or more, they are made to last and are maintenance free.
Do driveshafts need to be balanced?
Like tires, your driveshaft should be balanced to promote safe operation and prevent failure.
How can you tell if your driveshaft is out of balance?

What causes a drive shaft to go out of balance?
If driveshaft is suspected of being out of balance, check for missing balance weights, broken welds and any build up of dirt or paint that could cause the driveshaft balance to be affected.

Loose or damaged engine mounts may also be to blame if your car shakes when accelerating. As previously mentioned, damaged and loose engine mounts can’t efficiently absorb the vibrations produced by your cranking engine, so you’re likely to feel them when you step on the gas.
Is a 2 piece driveshaft better?
“A two-piece driveshaft is a great item when built and balanced correctly,” says Denny Bringhurst of Denny’s Driveshafts. Denny also reiterates that two-piece units will allow the driveshaft to maintain a higher critical speed, which is essentially a redline rpm maximum of a driveshaft.
How long can a aluminum drive shaft be?
To look at the chart another way, if your driveshaft is spinning at 6,500 rpm, the safe, maximum length of the 3-inch mild-steel driveshaft is 48-inches, a 3.5-inch 4130 shaft can be 52-inches long, and the 4-inch o.d. 7075 aluminum shaft is good for 56-inches. Carbon-fiber takes you just over a couple of inches more.
Is an aluminum driveshaft worth it?
An aluminum driveshaft will let you rev faster and can reduce vibration. Although you will not technically gain any horsepower from a new driveshaft, you will considerably reduce drag from the heavier stock driveshaft, resulting in faster track times and a smoother ride.
At what speed does a driveshaft vibrate?
Driveshaft balance issues can generally be felt at vehicle speeds over 30 mph. shaft. A component that’s out-of-balance will never cause a second or higher order vibration, only a first order vibration.
