The Best Shocks for Grand Marquis Buying Guide

Choosing a shock for your grand marquis isn’t an easy decision. Your riding experience, your comfort, your journey environment, and your purposes for using your vehicle depends on this shock choice. We’ll try to help you with what you need to look at carefully before deciding on buying shocks for Grand Marquis.


You first need to select, for what purposes you’ll use your Grand Marquis. You can use your car for your riding, you can use it for wedding entries or it might be used for load carrying.

Whether you choose off-road or on-road, you need to select your shocks according to the road and environmental conditions. On bumpy roads, you need to focus on fewer vibration shocks while on-road riding, you might choose a shock that can cope with a silent environment.  


Budget is a determining factor. You can’t expect everything on a low budget. Also, a high price doesn’t ensure better quality. You need to choose a shock that serves all purposes with a minimum budget. We’ll suggest you go for optimizing features for an optimized budget.

What do we mean by optimum? Well, it means the features that are necessary and sometimes cross the demand expectation. This section doesn’t meet all criteria and also doesn’t leave the essential features behind. 

Shock Types

You will find 2 types of shock absorbers on the market. Oil and gas-filled shocks. Oil-filled shocks are expensive but ensure better dampening control due to their variable stiffness nature. On the other hand, gas-filled shocks have fixed stiffness and are easy to find in the market.

Braking and Steering

Try to choose a shock absorber that provides auto adjustment to your steering wheel and has excellent braking ability. Exceptional handling and control also ensure stability in your riding.


No one changes shocks continuously. And changing shocks over and over isn’t a good idea too as it hampers your economic condition. A shock with a longer life also ensures an improved lifetime of its supporting equipment.

Easy to Install

You will not find a mechanic near you now and then. So, buying a shock that is easy to install and doesn’t need an extra special tool always keeps you on the profitable side.
