Engine Swap

In this process, we disassemble an engine’s vehicle and carefully install it into another. Many of our customers opt for this service to upgrade their trucks’ performance while still being able to haul large loads at high speeds.

Engine Replacement

We specialize in engine replacement which involves replacing parts while keeping the same engine. Typically, this consists of head gasket repair, oil pan replacements, and fuel injection system repairs. This enables you to save the cost of purchasing a new engine as we can salvage working parts from your old engine and integrate them into the replacement.

Engine Conversion

This is a method of replacing an old engine with a new, compatible model to upgrade power and lengthen a truck’s lifespan. Heavy-duty trucks often require specialized engines, making it time-consuming to search for replacement parts. At Top Flight, we handle engine conversions daily, providing value in the form of expert workmanship, increased torque, and operational efficiency.

Emissions Services

Modern trucks are equipped with emission control technology that helps reduce the environmental effects of diesel exhaust. Over time, these systems can become blocked with soot and other particles, which can affect performance. We service elements of these systems, from the EGR to the DPF, to keep them running efficiently and prevent unexpected fleet downtime.

Gary Roberts

Ram 5500 blew out drivers side front wheel bearing thankfully in Kilgore on a 3000 mile x country work trip. Chose Top Flight. They sent out a wrecker on Sunday evening, took my truck in, and I put up at nearby hotel. Called first thing in the am with parts list and had my truck repaired in a few hours. I was back on the road to home. Excellent service, repairs, and value. I enjoyed your company, to include the wrecker service who dropped me at my hotel. Keep it up!
