Bolt On process

How our reman is built

Every long-block on this site comes out of the Bolt On remanufacturing program — not a backyard rebuild. Here's what 'remanufactured' actually means.

  1. STEP 01

    Teardown

    Engine stripped to bare components. Every part visually inspected, photographed, and logged before anything proceeds.

  2. STEP 02

    Magnaflux

    Block, crank, rods, and heads chemically tested for hairline cracks. Anything failing inspection is scrapped — not reused.

  3. STEP 03

    Machine

    Block decked, cylinders honed or sleeved, crank polished or reground, heads pressure-tested and resurfaced — back to OEM tolerance.

  4. STEP 04

    New components

    Bearings, rings, gaskets, timing set, oil pump, valve seals, lifters — all new from OEM-spec suppliers, never reused.

  5. STEP 05

    Assembly

    Torqued to factory sequence by certified reman technicians. Oil clearances, valve lash, and end-play measured and logged.

  6. STEP 06

    Dyno

    Every long-block run-in and load-tested before it leaves the facility. Compression and leakdown logged per engine.

All backed by a nationwide 3-year, 100,000-mile warranty — parts and labor. If it fails, we make it right.
