Catalytic Converter for Ford Ranger (1995-1997) 3.0L 4.0L Rear

Direct-Fit Rear Catalytic Converter for 1995-1997 Ford Ranger (PN105)

What it Does: The rear catalytic converter replaces worn or clogged factory emissions units on the 1995-1997 Ford Ranger to restore exhaust velocity, clear catalyst efficiency trouble codes, and maintain legal tailpipe compliance.

The Stock Ford Ranger Exhaust Restriction & Catalyst Breakdown

Factory exhaust converters on high-mileage PN105 chassis trucks regularly suffer from thermal fatigue, washcoat sintering, and internal ceramic core fracture. Over decades of heat cycling, unburned fuel from the aging pushrod V6 architectures contaminates the substrate matrix, leading to excessive exhaust backpressure, restricted high-load engine breathing, reduced fuel economy, and persistent P0420 catalytic efficiency diagnostic fault codes.

The Engineering Solution

Built as a direct replacement assembly for the factory rear location, this unit features a robust stainless steel outer shell engineered to resist oxidation and road debris impact. Internally, a high-flow ceramic honeycomb substrate is coated with noble-metal catalyst loadings (platinum, palladium, rhodium) to optimize conversion efficiency without choking exhaust scavenging. Precision-welded direct-fit flanges allow bolt-on mating to the existing factory exhaust layout without cutting, bending, or custom TIG welding. The unit interchanges directly with part number 53254 and includes installation hardware and gaskets to ensure a tight, leak-free seal.

Frequently Asked Questions

Does this fit the PN105 Ranger?

Yes, this is a direct fit for the 1995-1997 Ford Ranger equipped with either the Vulcan V6 (3.0L) or Cologne V6 (4.0L) engine.

Will this clear catalyst efficiency DTCs like P0420?

Yes, replacing a fouled or depleted secondary converter with this fresh ceramic substrate restores proper gas reduction and resolves converter-threshold diagnostic codes when the upstream fueling is healthy.

The Ford Truck Reliability Standard

Built for the real-world demands of light-truck towing, hauling, and daily work cycles, this converter preserves critical low-end torque while eliminating unneeded exhaust bottlenecks under payload.
