Product Overview
Wiseco BoostLine Ford EcoBoost Conrods FD6012-905 – Forged V6 Engine Upgrade
The Wiseco BoostLine Ford EcoBoost Conrods FD6012-905 are a premium forged connecting rod set engineered for high-performance Ford 3.5L EcoBoost V6 engines and suitable specialist applications using compatible Ford 3.7L V6 engine dimensions.
Designed for demanding forced-induction engine builds, these BoostLine connecting rods combine 4340 forged steel construction, a patented three-pocket I-beam design and ARP 2000 fasteners to support strength and durability under increased cylinder pressures.
Supplied as a complete set of six connecting rods, FD6012-905 is intended for professional engine builders developing high-boost Ford EcoBoost engines for performance road use, drag racing, track applications and motorsport.
Why Choose Wiseco BoostLine Ford EcoBoost Conrods?
1. Premium 4340 Forged Steel Construction
BoostLine manufactures its performance connecting rods from high-strength forged 4340 steel.
This material is widely used in demanding performance engine applications because it offers the strength required for components subjected to repeated high combustion and inertial loads.
For heavily modified Ford 3.5L EcoBoost engines, forged connecting rods can be an important upgrade when increasing turbocharger output or developing a new engine specification.
2. Patented Three-Pocket I-Beam Design
The FD6012-905 uses BoostLine’s distinctive three-pocket I-beam construction.
Rather than relying on a conventional performance H-beam configuration, the BoostLine design positions material strategically to improve strength and big-end stability.
According to BoostLine’s testing, the design offers:
- Approximately 60% greater bending strength than the H-beam designs used in the manufacturer’s comparison
- Approximately 20% lower tensile stress in the manufacturer’s testing
- Improved resistance to demanding loads in high-output engines
These figures are design comparisons reported by BoostLine, not universal guarantees against every competing connecting rod.
3. ARP 2000 Connecting Rod Fasteners
High-strength connecting rod fasteners are essential when building an engine intended to operate at elevated power levels and engine speeds.
The FD6012-905 kit includes ARP 2000 connecting rod bolts.
These fasteners are intended to support reliable big-end cap retention when fitted according to the correct manufacturer instructions.
The bolt part number must be checked against the current supplied hardware before installation.
4. Designed for High-Boost Ford EcoBoost Builds
Ford’s 3.5L EcoBoost V6 engine offers substantial performance development potential, particularly in specialist performance and motorsport applications.
However, increased turbocharger boost, cylinder pressure and operating RPM place greater demands on the engine’s connecting rods.
BoostLine designs its forged connecting rods specifically for demanding forced-induction applications and markets the range for extremely high-output engines.
The manufacturer states a capability of up to 1,500 hp for suitable six-cylinder builds. This is not a guaranteed safe output for any specific engine or vehicle.
5. AMPCO Bronze Wrist Pin Bushings
The FD6012-905 connecting rods incorporate premium bronze small-end bushings designed for compatible floating wrist pin arrangements.
The manufacturer specifies a wrist pin diameter of 0.906 inches.
Piston compatibility must be confirmed before assembling the engine, especially when using aftermarket forged pistons.
6. Precision Inspection and Quality Control
BoostLine uses a detailed 26-point coordinate measuring machine inspection process.
Each rod set is supplied with a dimensional inspection report covering critical measurements.
For a professional engine builder, this information helps support the inspection and measurement process required when preparing a performance rotating assembly.

Ford 3.5L EcoBoost and 3.7L V6 Engine Compatibility
The Wiseco BoostLine FD6012-905 connecting rod set is listed for Ford 3.5L / 3.7L V6 applications, with the manufacturer’s primary emphasis on the Ford 3.5L EcoBoost engine.
Compatibility is determined by the actual engine configuration and rotating assembly dimensions.
Before ordering, verify the connecting rod length, wrist pin diameter, big-end journal, piston specification and crankshaft arrangement.
Do not assume that every Ford 3.5L or 3.7L V6 engine uses interchangeable connecting rods.
Are BoostLine Forged Connecting Rods Worth Upgrading?
Factory connecting rods are designed for the original manufacturer’s performance and durability targets.
When an engine is modified for significantly greater cylinder pressures and power, the rotating assembly may need to be upgraded accordingly.
BoostLine forged connecting rods offer additional engineering features intended for demanding applications, including strengthened forged construction and precision inspection.
Connecting rods do not directly produce more horsepower. Instead, they provide the mechanical capability to support a properly specified high-performance engine build.
Installation and Engine Building Requirements
Professional engine assembly is strongly recommended.
Your engine builder must verify:
- Connecting rod length and engine geometry
- Crankshaft journal dimensions and bearing clearances
- Piston and wrist pin compatibility
- Rod-to-block and rotating assembly clearances
- Engine balancing requirements
- Actual supplied ARP fastener specifications
- Correct bolt stretch or installation procedure
- Oil clearances and engine lubrication requirements
- ECU calibration and operating RPM targets
Never use an assumed bolt torque figure or rely solely on the product listing when assembling a high-performance engine.
