A hydraulic cylinder rod is a rotary joint that holds a fixed position of constant contact between two sections, with some extent of rotary freedom on all three axes. Hydraulic cylinder rods are widely used to connect the ends of main steering links, control rods and other tie rails used for controlling the movement of the rolling wheels on a vehicle. Cylinder rod ends vary in length depending upon the length required for connecting the main and control sections of the steering mechanism.
There are two common types of Rod Ends: Spherical and In-plane. A spherical joint has the common feature of two flat surfaces with a slightly curved profile at the junction. Spherical joints are generally suitable for use in situations where the rod or axle has high bending loads, as they provide very good mechanical advantages at the joints. However the drawbacks associated with the use of spherical joints are that they have high stress strengths and fatigue factors, and the angle of symmetry increases with increasing diameter of the sphere. The center-line of a spherical joint increases along with the diameter of the sphere, increasing the joint's center line diameter and thus decreasing the axial load.

The other common type of Rod End is the in-plane joint, which is more rigid and reliable than the spherical joint and has lesser fatigue factors. In order to fit the different wheel sizes, most manufacturers make use of a variety of templates to obtain the best possible fit. The in-plane joint uses ball bearings that work by rotating the spherical joint inside the bore of the wheels.
An alternative to the roller and rod ends is the steering rack. Steering racks are installed at the end of the steering column to counterbalance the wheel axle. The concept behind this device is that the smaller the steering rack, the less control pressure is imparted to the wheel, reducing the risk of loss of steering or control when the vehicle starts to move. The steering rack can be either directly fixed to the frame, or mounted via rack crossbars that pass through the wheel hub. In many modern vehicles, rack installation is combined with the installation of tie rod ends.
Another option for obtaining a high quality steering system, even in today's high-tech vehicles, is the rack and pinion steering system. This is often used in off-road applications such as trucks or SUVs. It is commonly constructed from a combination of steel tube and pinion springs. Because of the higher tensile strength of the steel tube, the rack system requires more force to keep it in place, leading to better steering control.
In addition to providing superior steering control, a suspension system offers better suspension operation under a variety of driving conditions. The four-link rear suspension, commonly called the riser bar system, uses the upper and lower links to provide greater clearance under a variety of circumstances, including lateral (tow, lateral hitches), longitudinal (firing) and steering. Air suspension systems use air-bags along with suspension and struts to provide improved control and stability at the front end of the vehicle. Standard vehicles often have air Suspension but specialty vehicles may use other types of suspension systems, such as the MacPherson strut, which uses air-bags along with a front strut brace to improve vehicles' performance and chassis life. Most high-performance vehicles also employ hydraulic struts, which are made of a high-tension hydraulic system that allows the engine to work harder, and provides better weight distribution over the engine and axle.
Sometimes referred to as the "shaker system," a Racing Tip (or Shaker) can be fitted to the front end of the vehicle to reduce vehicle noise pollution. A Racing Tip's purpose is to enhance the sound wave patterns emitted by the tires, thereby reducing the noise pollution caused by tire clunking. With a Racing Tip, you can get rid of some of the tire noise pollution that occurs when tires make contact with one another. This can be particularly helpful when driving on rural roads or near other quiet areas.
Rod End kits or suspension enhancements can be used on any type of automobile to minimize vehicle chatter, especially if you are a passenger, because they can easily be removed without harming your car. When using a Rod End in conjunction with a steering system, you will likely experience a more significant reduction in tire noise than with an independent steering system alone. Rods are usually used in combination with other types of steering aids, such as track rod ends, track bar ends and tie rod ends. Using one type of steering aid, such as a track rod end or a track bar end, will most likely increase the overall efficiency of your vehicle's suspension system.
