I won't lie, the prospect of removing/replacing the coil spring was scary for me to raise my 2003 2.5" Jeep Wrangler X. After watching a few videos on YouTube and many years of auto repair experience, I bought this tool and got used to it. This product was very well made and durable and made the job very manageable. It still wasn't a cakewalk, but the built-in security features and ease of use made this a must-have if you're making this type of upgrade.
