Key Features & Benefits – Lada lightweight forged connecting rod set H-beam 146 mm
Lada lightweight forged connecting rod set H-beam 146 mm is made from 4340 forged steel for high-load engine builds. Compatibility: designed for Lada 8V classic engines and Lada VFTS applications.
The set uses ARP2000 fasteners in 3/8" size, with defined build-critical dimensions: 146 mm center-to-center length, 20 mm wrist pin diameter and 51.33 mm big-end bore. Weight is 539 g (without bolts), which matters when planning rotating mass.
When is this useful?
When you build a reinforced bottom end for a Lada 8V or VFTS project, fixed rod length and interface dimensions make it easier to plan crank, piston and clearance geometry consistently, while the H-beam format supports stability under load.

Selection & installation tips
- Crank journal & bearings: Confirm the big-end and bearing shells match your crankpin size and bearing specification.
- Pin interface: Match the small end to a 20 mm wrist pin and your chosen pin retention method.
- Geometry planning: Use the 146 mm length together with stroke and piston compression height to verify piston position and clearances.
- Side clearance: During test assembly, check rod side clearance and ensure there is no contact with the block or crank counterweights.
- Fastener control: Keep your tightening method consistent for the ARP2000 3/8" bolts and inspect bolt condition before assembly.
Before final assembly, verify crank and pin interfaces, the 146 mm length, the 51.33 mm big-end bore and the fasteners, then compare them to the technical specs listed above.
