VEGE DFDH 4.0L 245ci Car Truck Long Block Remanufactured Crate Engine

Description

Featuring precision line-bored main bearing tunnels, the VEGE DFDH Remanufactured Crate Engine 4.0L 245ci long block package restores durable truck performance. The pushrod V6 generates 160 horsepower at 4,200 RPM and 225 lb-ft torque at 2,800 RPM. Thoroughly reconditioned cylinder heads and balanced rotating components restore smooth idle quality and low-speed crawling torque across sport-utility platforms.

A thick-wall cast iron 60-degree block casting incorporates four-bolt center main caps clamping a balanced cast iron crankshaft. Forged I-beam connecting rods support hypereutectic pistons across an 3.952-inch bore and 3.323-inch stroke. Compression ratio checks in at 9.0:1 for detonation suppression. The stamped steel rear-sump oil pan holds 5.0 quarts, with complete dry mass registering at 390 lbs.

Key Features of VEGE DFDH

Technicians choose to buy VEGE DFDH crate engine assemblies to repower classic Explorer and Ranger chassis without custom modifications. Every unit meets original production standards to deliver dependable propulsion across tough off-road trails and daily highway commutes.

• Pushrod-actuated valvetrain uses hardened pushrods to prevent bending under sudden gear downshifts.
• 45 mm intake valves flow abundant air into wedge-shaped combustion chambers for strong low-RPM pull.
• DFDH replacement packages feature thick casting head designs that eliminate historical heat cracking issues.
• Micro-finished main journals establish uniform hydrodynamic lubrication films under heavy engine loads.
• Plateau-honed cylinder walls establish prompt piston ring seating and low oil consumption.
• Brand new hydraulic roller lifters eliminate valvetrain tick while reducing frictional drag.
• Heavy-duty timing chain sets maintain exact camshaft timing through severe off-road driving cycles.

Combustion Chamber Dyno Characteristics

Operating across an engine band from 1,200 to 4,800 RPM, this V6 outputs 160 peak brake horsepower at 4,200 RPM and 225 lb-ft torque at 2,800 RPM. Camshaft duration measures 186 degrees intake at 0.050-inch lift, with 0.415-inch valve lift. The motor runs on standard 87-octane pump gasoline. Intake manifold vacuum reads 19 in-Hg at 650 RPM, supported by 40 to 60 PSI oil pressure hot.

Chassis Clearance Transaxle Integration

The bellhousing flange bolts straight to Ford A4LD, 4R55E, and M5OD-R1 transmissions without special adapters. External balance requirements demand use of factory-weighted flywheels or flexplates. Sump contours drop cleanly around front four-wheel-drive differential carriers, leaving generous room for starter motor clearance, steering linkages, and exhaust downpipes.

Maintenance Protocols Operating Boundaries

Pressurize oil passages using a mechanical priming tool before initiating the first startup cycle. Fill the crankcase with 5W-30 motor oil with anti-wear additives and purge air from the radiator. This remanufactured long block is not engineered for centrifugal superchargers, turbo setups over 5 PSI, or off-road mud bog racing.

• Discard the break-in oil and change the spin-on filter after the first 50 miles.
• Change motor oil and check valve train noise every 3,000 miles of driving.
• Flush engine coolant and inspect radiator hoses every 12 months for steady cooling.

Factory Warranty Crate Contents

Protected by a 36-Month / 100,000-Mile limited warranty covering remanufactured parts and machining. The wooden crate contains the remanufactured long block, complete oil pan, reconditioned cylinder heads, pushrods, timing cover, balance certification report, and a detailed installation manual.
