Considering the complexity and cost of most coil over suspensions, the aftermarket world is somewhat limited to a few key manufacturers. More affordable options and new manufacturers are becoming more common as time progresses. Overall, the market is still considered a niche segment with few choices.
Most systems currently available allow for height adjustments from 3.5” to 6”. It’s important to keep the height range in mind during installation. At a 3.5” of height, the system can run with little to no other suspension geometry modification. However, once the Jeep has been lifted over 4-inches, there are several important components that will need to be replaced/adjusted to correct the overall suspension geometry. In addition, some coil-over kits are referred to stage 2 and involve a much more involved overhaul of the Jeep’s frame and suspension. This, in turn, produces a stretched-out wheelbase for better articulation and overall suspension travel. These more complex kits are usually installed by trained mechanics and involve a higher labor rate.
Coil over kits also require more maintenance, especially in colder climates where the Jeep is exposed to snow and salt. The elements can work themselves into the threads of the shock body and sometimes seize the spring perches, preventing them from moving for any type of adjustment. Within those conditions, it’s always best practice to remove each coil over and fully disassemble for proper cleaning and maintenance several times a year. This level of up-keep can be problematic for some owners but is an important factor when considering coil overs.
Lastly, due to the complexity of the systems, most coil over kits are fairly expensive. With most kits starting at over $1,000, the systems can easily climb over $4,000 for the kit alone. This isn’t considering other suspension elements you might need to take full advantage of the benefits of a coil over kit. The price also doesn’t include installation which often times requires the help of a professional, bringing the overall cost of a coil over kit to a substantial investment.
