Overview
The Manley 14008-4 is a set of four forged 4340 steel H-beam connecting rods for the Toyota 3S-GTE. They replace the factory rods with a stronger, weight-matched assembly that withstands the higher cylinder pressures of boosted, high-RPM builds.
Aimed at MR2 (SW20), Celica GT-Four / All-Trac and other 3S-GTE turbo builds running raised boost, upgraded turbos or higher rev limits where the OEM rods become the weak link.
