In 1987, Jeep gave the world a CJ-7 that you could live with every day. The YJ Wrangler received modern advancements like ABS, automatic transmissions, and fuel injection to make living with your off-road legend easier on a day-to-day basis. If the old, reliable inline-4 or inline-6 isn't quite enough, check out our Gen III/IV LS swap parts below to give your Wrangler a firebreathing Chevy heart.
