The 2.5 inch Stock Mod System is the perfect starting place for JK owners looking to get a little lift at a great value. The Stock Mod system features a progressive rate front coil to allow the same great travel our 3.5" systems offer at a 2.5" lift height. Our heavy duty double adjustable front track bar perfectly centers the front axle and maintaining a perfect factory steering relationship. Adjustable sway bar disconnects are also included for improved off-road ability, but they can also be installed as fixed longer links! The rear end features our bomb proof rear track bar bracket to properly center the rear axle and enhance the roll center in the rear for precise handling. The rear coils are a standard rate coil to provide excellent payload and towing characteristics on road. The Stock Mod System is easily upgraded to any of our other systems. This system will allow for up to 35 inch tall tires and is backed by an exclusive Abuse Proof Lifetime Warranty on all Hard Parts!
