Lengthen the wheelbase and center the rear wheels on your JK Wrangler/Unlimited with the TeraFlex JK: 2in Alpine Rear Stretch Kit & Front Long Control Arm Kit. The additional 2in stretch improves wheelbase characteristics including climbing under extreme conditions as well as rear tire clearance. The new relocation brackets ensure the rear coil springs (NOT INCLUDED) remain vertical to prevent spring bowing. Although it�s been designed for aftermarket �high-linein fenders, this kit will still work with the factory fender flares. Includes Front Alpine Long Control Arms and Brackets for use with 3�6in lift coil springs. This kit is for those who want a long arm suspension system with their rear stretch kit!
