Suspension Rebuild Kits – How Do They Work?

Are you planning to replace your suspension rebuild your existing suspension? If yes then you must first plan and prepare properly for the job. It is not an easy task to do this because of the complexity of the suspension designs, because of its components and the various factors that need to be considered. In this article, we will be discussing how to decide the suspension rebuild cost.

Suspension Rebuild Kit

The basic suspension rebuild kit includes 4 torsion bars, 8 A-arms, two outer suspension bushings, 1 inner tie rod, and rubber bushings. To determine the suspension rebuild cost, it is necessary to know the suspension type and the drive system used on your vehicle. Based upon this information, suspension engineers can then calculate the weight that needs to be supported by the suspension and calculate the torsion length needed for the particular suspension. Based on this information, suspension engineers can then decide the type of suspension they would like to install.

The first thing that you should consider in determining the suspension rebuild kits is the type of suspension that is in use on your vehicle. There are four types of suspension rebuild kits, namely, independent suspension, payload suspension, strut mounted suspension and the after-market suspension. Independent suspension rebuild kits use upper and lower links of the suspension. The preload suspension uses lower links and the strut mounts the upper link. strut mounts are usually placed higher on the vehicle because they are more adjustable. In most cases, the after-market suspension kits are utilized by sports cars and high-performance vehicles.

Next, consider the modifications that you would like to make. The modifications that are done to the suspension system before replacing the suspension, usually include replacement of spring struts, strut towers, shock towers, control arms, and tires. To calculate the amount of suspension rebuild kits that you will need, it is necessary to figure out the weight of your vehicle. Your vehicle’s weight, as well as its clearance on the front end, are also important things to consider. When you install drag shocks, it is advisable to replace both the spring and shock absorbers.

Since the suspension rebuild kit mainly concerns the suspension bushings, it is also necessary to measure these parts. As a general rule, the length of the suspension bushings is one-fifth of the vehicle’s overall length, excluding the tires. Moreover, it is also advised to purchase new bushings since the ones that are used with the suspension rebuild kits are often used-outdated. The new bushings must be long enough to avoid rubbing against each other. The new ones must also be able to withstand extreme weather conditions.


The new suspension bushings and the suspension ball joints are installed by attaching them to the existing suspension by welding or riveting. The parts are held in place by stainless steel rivets. The 4 strut rod bushing kit must be installed to the engine block using an engine mount kit or by bolting them to the frame. Once the suspension is done, the rear suspension is then adjusted by installing rear end braces and struts.

The final step involves installing front suspension mounts. The final step entails the installation of tire struts and rear suspension mounts. The price for this operation is dependent on the number of components and the materials that are used. You can expect to spend between three thousand and eight thousand dollars for this job.

The total cost of the suspension rebuild kit depends on the amount of work and materials that will be involved. As a note, the performance of your suspension depends on the make, model, and year of your car. The condition of your suspension can determine how smoothly the car performs. Therefore, always check your suspension if it is in good shape before performing any important maintenance. If you find a bent control arm bushings or damaged strut bushings, the suspension may need to be replaced with new ones to improve your car’s performance.
