Fully remanufactured, not just rebuilt.

Starters & Alternators

A car that won’t start puts a stop to your day. Duralast Starters and Alternators are remanufactured, replacing all wear components and mal-functioning assemblies, not just rebuilt with the original cleaned-up pieces. To ensure OE or better amperage and torque output, Duralast 100% triple-tests each part at the component, sub-assembly, and finished unit levels, so you can install with total confidence. And where the OE has known design flaws, Duralast develops an innovative solution.

Engineered for OE Quality or Better

Triple tested at component, sub-assembly and end of line to ensure OE or better amperage output.

Remanufactured Not Rebuilt

All bearings and wear components are replaced 100% new with premium bearings for increased durability, performance and longer service life.

Clean, Coat and Protect

Rotors are cleaned, tested and windings are coated to protect the insulation for OE performance.

Optimum Output

Stators are thoroughly cleaned, tested and coated for optimum electrical output.

100% New Brushes

100% new, lead free premium brushes for optimum performance and longer service life.

Tested & Proven

Rectifiers are 100% electronically tested under variable loads to ensure consistent performance under all driving conditions.

Precision Polished

Slip rings are precision polished for maximum contact resulting in consistent output performance and longer service life.

The Strictest Standards

Triple tested at component, sub-assembly and end of line to ensure OE or better torque output.

Crank Strong

Solenoid contacts are subject to wear and arcing erosion, reducing conductivity and service life. Solenoid contact is inspected and 100% new to ensure clean consistent contact and high conductivity for strong cranking every time.

No Corners Cut

Starters use 100% new bronze sintered bushings for maximum performance and wear resistance.

Start Right Every Time

Precision engineered and machined armatures are manufactured to assure maximum electrical torque output performance and unrivaled durability.

Solid Consistent Output

Electronically tested commutators provide consistent electrical output and reliable starting performance at every turn of the key.

Built to Take the Heat

Starter drive clutches are fully dismantled, remanufactured, then sealed with aerospace quality grease to ensure maximum performance and durability.

100% New Brushes

Brushes are 100% new, quality and durability tested for unmatched performance and reliability.
