How to Install Gas Shocks in a Vehicle


The gas shock absorbers contain nitrogen which limits the amount of foam that can build up due to the stock shocks. The use of gas shocks increase the ability of the vehicle and thus provides a smooth movement. Installing gas shock absorbers in an automobile is cost effective and provides better performance. Shock absorbers in vehicles are to be replaced every 70,000 miles. Worn out or damaged shock absorbers can cause poor handling or even a bouncy ride and may cause noise. Gas shock absorbers can be purchased in any auto parts store such that fits into the vehicle. 

Basically there are 2 types of shock absorbers, gas operated and heavy duty shocks i.e., they are either gas-filled or spring-operated. Gas-operated shock absorber works similar to a spring-operated type. When a vehicle hits a bump on the road, the gas inside the shock absorber compresses. The driver inside the vehicle experiences much less of the road impact using these type of shock absorbers. With the vehicles that are designed for off-road driving and monster truck racing, the type of shock absorbers used is critical. Vehicles make use of gas-powered shock absorbers on their rear axles to provide cushion from harsh road conditions, and it provides stability to the vehicle at high speeds. These gas shocks can wear out or age and may require replacement. Gas shocks can be installed by a  trained mechanic or by yourself, if the correct procedure is followed. Given below are a set of steps to be followed when installing gas shocks into a vehicle

Tools and Materials Needed:

  • Screwdrivers
  • Socket set 
  • Lug wrench 
  • Floor jack  

Step 1 - Removing the Wheel  

Raise the vehicle using the floor jack. Dismantle the wheel and tire using the lug wrench by turning the nuts in a counter-clockwise direction. Keep the wheel and tire aside.

Step 2 - Loosening the Shocks

Loosen the lower shock absorber and mount the nut by turning it in a counter-clockwise direction, make sure not to remove it completely.

Step 3 - Removing the Stock Shocks 

Remove the top mount bolts or the twin mounting screws or single mount post nut by turning them in the counter-clockwise direction. Now, the shock's eyelet will either go through the mount bolt, or will be mounted to a plate that fastens underneath the vehicle. The front shocks will be mounted into large holes at a vertical angle, protected by the bushings. Remove the lower mount nut by turning it out completely. The stock shocks will slide, completely out of the vehicle.

Step 4 - Installing the Gas Shocks

Replace the stock shocks with a new gas shocks by positioning it onto the upper mount bolt. Lock it up to the top mount, but ensure not to tighten the nuts or bolts completely.

Step 5 - Final Step

Line up the lower mount bolt and cut the keeper strap on the new shock. Press the lower eyelet onto the mount bolt as the shock decompresses. Tighten the lower mount nut in a clockwise direction using a wrench. Tighten the upper mount nuts completely. Replace the wheel and tighten the nuts in a clockwise direction. Finally, lower the vehicle from the floor jack carefully.
