They are bars which mount on the rear axle, under the leaf springs of a rwd car or truck. As you accelerate the torque will cause the axle rotate up at the front. The traction bar has a bump stop at the the front that when this happens contacts the front mount of the leaf spring. This contact causes the wheels to be driven into the pavement(more taction).
Traction bars are for suped cars. It does exactly what the word is. Traction. Nothing really to do with performace engine wise. If I had a hot rod Id invest in a good pair of bars. Cheap ones might look cool but if racing they might get you to the track with out the tion!
you don't need traction bars but you need air shocks to fit that size of wheel and tire.
A set of traction bars will all but eliminate wheel hop.
the top faces the nose of your skimboard and the bottom faces your traction pad
no place has them, you will have to rebuild the springs yourself or get traction bars from summit racing or Jeggs.
It is the strip of traction that the skimmer uses to keep his front foot in place. Arch Bars replace the use of wax on the top half of the board.
No - 1991 to 1994 Explorers had the twin I beam or twin traction beam front suspension with coil springs and in 1995 went to upper and lower control arms with torsion bars.
When the traction light is on you have the traction control turned on in your vehicle and traction control is activated. Traction control is applying brakes to a wheel that losing traction.
Tires have the biggest effect on traction. Getting wider or stickier performance tires will greatly improve traction. You have to be careful not to change the tire diameter/height too much or your speedometer will be off. Also if your rear doesn't have one, Adding a limited slip/posi/locker will give you more traction. After doing that, traction devices like traction bars/ Cal-tracs would be the next step. Your truck probably has a 10 bolt and swapping it will not give you more traction. If your truck has steep/low gears like 4.10s, going to 3.73/3.42/3.21/3.08 will reduce traction issues and acceleration but improve fuel economy/reduce highway rpm.
poor traction
Skin traction and skeletal traction are the two types.
Everything has traction.
