  • Full in-house dynamometer testing
  • Best option for extreme high-hour engines

Option 02 (RECOMMENDED SERVICE)

IN-FRAME OVERHAUL

  • Engine remains physically in the chassis
  • Lower total cost compared to complete reman
  • Significantly faster shop turnaround times
  • Ideal for targeted internal component failures

HOW IT WORKS

Your In-Frame Overhaul in Three Steps

We deploy strict diagnostics to ensure your block’s integrity before any wrench turns, delivering a clean slate without pulling the block.

01

DIAGNOSE & QUOTE
We thoroughly inspect your engine, confirm an in-frame overhaul is the ideal and safe path forward, and provide a transparent, upfront cost quote with zero hidden fees.

02

PRECISION REPAIR
Our master technicians handle targeted teardown, block cleaning, honing, and replace wear components (pistons, rings, bearings, seals) to exact OEM tolerances in chassis.

03

TEST & RETURN
We run rigorous in-frame pressure, compression, and oil system evaluations to ensure absolute stability and verify perfect performance before your machine heads back to the road.
