However, finding the best-quality aftermarket shock could be challenging, as they are often calibrated to meet the specification of OEM. If you own a GMC Sierra 150, you are lucky enough to find plenty of shocks on the market. We have reviewed the seven best shocks for GMC Sierra, which you can buy in 2021.

Top Shocks For GMC Sierra 1500

1. KYB 349068 Excel-G Gas Shock

KYB 349068 Excel-G Gas Shock

 

KYB is the world-famous brand that manufactures and supplies struts, shocks, and other automotive parts to vehicle manufacturers and aftermarket dealers. Excel G-shocks by KYB are designed for promising stability and responsiveness during the ride, stopping, taking turns, and changing the lanes. The feature that impressed us most is the performance of this shocks struts set.

The shocks come equipped with in-house valve damping giving you 40% more damping than regular shocks. After pairing these shocks with the GMC Sierra 1500 model, we noticed a significant improvement in steering response, tire contact, body movement, and stopping distance. The shocks use the industry’s leading-quality materials, making them one of the most rugged shocks for GMC Sierra.

The shocks feature a strong body coupled with a triple lip fluid seal that prevents fuel leakage and adds exceptional stability to the whole suspension system. Additionally, that zinc-plated piston and chrome-plated piston seal slows down the wear and tear in seal rings, giving you a long-term performance. It comes with a rubber boot in the shaft that keeps the dirt and debris away and prolongs the life of tires and the whole suspension system.

It also shows the universal compatibility with the electronic safety systems of all the suspension systems. We found it extremely natural with the electronic safety system of the GMC Sierra. This is one of the thickest shock and strut systems we ever used. Although the maximum thickness reduces flex and adds stability, it cuts down the space for fuel storage, which results in quick warming. Therefore we do not recommend these shocks for regular off-roading.

Pros
  • 40% more dampening
  • Best construction quality
  • Tripe lip fluid seal to prevent leakage
Cons
  • Not ideal for regular off-roading

Buying Guide

Pairing your truck with a reliable set of front struts and rear shocks is critical to get stability and comfort. A good set of shocks offer the price to protect your suspension system and enhance the vehicle’s service life.

While finding the aftermarket automotive parts, you should be more investigative to avoid compatibility and quality-related issues later. Here is a comprehensive guide on the features you must consider for buying the best shocks for GMC Sierra.

Twin Tube Vs. Monotube

Twin-tube shocks are ideal for regular use and on-road applications. These shocks generally come inexpensive and make the best deal for people who are engaged in regular highway rides. However, these shocks cannot withstand the fast speeds and challenging conditions as they tend to mix the fuel and air and can heat up quickly.

On the contrary, monotube shocks are designed to withstand rough and tough off-road conditions. These shocks are mounted upside down giving a quick response. These shocks do not heat up quickly and respond to the changing weather condition. Although these shocks are expensive, it is critical to get them if you do regular of-roading.

Compatibility

Compatibility is one of the most critical factors you should consider while buying aftermarket shocks for your vehicle. While roaming around the market, you will come across thousands of replacement options but remember, all of them are not your perfect match.

You can search online by entering the vehicle model and year variant. Finding a compatible aftermarket part is crucial to avoid fitting adjustment and performance issues later on. You can find the most reliable compatibility information on the manufacturer’s website.

Durability

Shocks act as a protective system and increase the service life of other automotive parts. Therefore durability of the shock and suspension system is the most critical. Low-quality shocks wear out quickly, which leads to fuel mixing, gas leakage, and less responsiveness. This situation results in poor road-tire contact, making your rides unstable.

Therefore you should go with top-notch construction quality for shocks like cast iron, metal alloy, and steel-alloy, etc. Additionally, the outer-core protection layer also plays an integral role in minimizing shock wear. The piston seal and exterior of the shock should be resistant to rust and corrosion. Chromium-plated or zinc-plated shocks and pistons are the best options.

Ease of Installation

Replacement of shocks is a costly process, as the shock and leveling kits come considerably expensive. If the installation process is time-consuming and complex, you may need to go with a professional installation that will add more cost.

Therefore it is recommended to go with the shocks that come with pre-assembled parts, comprehensive guides, and feature easy to mount designs. You can install such kits easily, even if you have little experience in automotive parts. This will save you time, energy, and cost.

Type Of Fuel

Shocks either use gas or oil as fuel. Oil-charged shocks are the least expensive and are ideal for regular use and light-duty application. The major downside of the oil-charged shocks is aeration. The formation of bubbles results in delayed response and negatively affects the suspension performance. Advanced shocks and struts are gas-charged that use a mixture of oil and gas.

These socks use low-pressure gas that reduces the problem of aeration and results in the best steering response. The inexpensive gas-charged shocks oxygen as a fuel, but such shocks cannot withstand the challenging condition. Low-pressure nitrogen gas is used as the best fuel for shocks and struts. These shocks are ideal for heavy-duty applications like towing, hauling heavy loads, and off-roading.
