Direct answer: The four-door Wrangler Unlimited made the Wrangler practical for more families and daily drivers. That broader use changed aftermarket demand: buyers increasingly expected lifts, shocks, tops, interiors, and driveline upgrades to preserve comfort and road behavior. The JK did not create Jeep modification, but it enlarged the market and raised expectations for complete, integrated builds.
A different customer
The extra doors and usable rear seating made the Wrangler easier to justify as a primary vehicle. More daily use put noise, ride, handling, braking, and durability under greater scrutiny.
A different aftermarket
The market increasingly rewarded systems rather than isolated parts: matched suspension packages, vehicle-specific tops, engineered bumpers, brake upgrades, and accessories designed around electronics and safety systems.
