2020 Kenworth T880

Category, Truck. Mileage profile, 312,400 miles suggests a highway and vocational mix where chassis wear items, cooling stack condition, and driveline joints become the deciding factors more than cosmetics. Identification, VIN 1XKZD49X7LJ385658 and stock 0633991 support traceability for service history, recalls, and build sheet verification. Powertrain, engine, transmission, axle ratio, and ECM details are not provided, so application fit cannot be tied to horsepower, gearing, or PTO capability without the build sheet or ECM report. ECM field is blank, so an inspection should include an engine hours pull, idle percentage, fault history, aftertreatment status, and any programmed parameter changes. Frame rails, sleeper structure, and cab mounts should be checked for cracks, rust jacking at fasteners, and evidence of previous upfit work common to T880 vocational spec. Fifth wheel, air lines, and electrical pigtails should be inspected for jaw wear, slider rail condition, and chafe points, plus a close look at steer tire wear pattern, kingpins, and front spring pins to confirm alignment and bushing health at this mileage.
