Catalytic Converter for Ford Ranger (1998-2000) 3.0L 4.0L Rear

Direct-Fit Rear Catalytic Converter for 1998-2000 Ford Ranger (PN105)

What it Does: The direct-fit rear catalytic converter replaces degraded factory emissions units on the 1998-2000 Ford Ranger to eliminate P0420/P0430 diagnostic trouble codes and restore unobstructed exhaust flow.

The Stock Ford Ranger Exhaust Restriction & Catalyst Degradation

Factory exhaust bricks on the PN105 chassis succumb over time to prolonged thermal cycling, carbon fouling, and washcoat degradation. On higher-mileage Vulcan V6 and Cologne V6 engines, unburnt hydrocarbons and elevated exhaust gas temperatures lead to internal honeycomb fracturing or physical substrate melting. This failure generates severe exhaust backpressure, degrades low-end torque, spikes cylinder head temperatures, and inevitably triggers a Check Engine Light due to sub-threshold catalyst efficiency.

The Engineering Solution

Engineered as an exact bolt-in replacement, this rear catalytic assembly features a heavy-gauge stainless steel outer shell designed to resist road salt corrosion and road debris puncture. Inside, a high-flow ceramic substrate is washcoated with active precious metal loadings to ensure complete post-combustion oxidation of HC and CO gases without generating parasitic backpressure. Precise OE-spec flanges and integrated hanger locations align with factory exhaust manifolds and intermediate pipes, eliminating the need for cutting or custom fabrication while matching original backpressure tolerances.

Frequently Asked Questions

Does this fit the PN105 Ranger?

Yes, this is a direct fit for the 1998-2000 Ford Ranger equipped with either the 3.0L Vulcan V6 or 4.0L Cologne V6 engine.

Will this direct-fit rear converter clear the check engine light?

Yes, replacing a fouled or collapsed substrate with this OEM-spec ceramic converter clears catalyst-efficiency diagnostic trouble codes (such as P0420) provided downstream O2 sensors and engine tune are functional.

The Ford Workhorse Standard

The PN105 Ranger earned its reputation through sheer mechanical reliability under payload and towing duty. Installing a durable stainless steel converter maintains proper exhaust velocity and engine backpressure, ensuring dependable pulling power and long-term drivetrain longevity.
