If you buy a lowering kit and install it yourself, it will be cheaper. While you can find lowering kits for as little as $500, you’ll generally want to stick to the $1,000-$1,500 range.
If you decide to have a mechanic install the kit for you, you’ll also have to pay for the cost of labor. Every mechanic has a different rate, but it’s usually around $80-$100 per hour. Spending on how familiar your mechanic is with the procedure, it could take anywhere from two to eight hours. Make sure to get a quote from a few mechanics before picking one.
