  • DESIGNED FOR YOUR REBUILD — The 4" hone matches engines with 3.751"–4.000" bores: Chevy 350/327/302, Ford 302/351W, Mopar 318/360, and GM 6.0L LQ4/LQ9. Optimized for deglazing and crosshatching cylinders that are round and in good condition — not a substitute for boring badly worn or out-of-round bores. Check your product label for exact size, or scan the QR code on the included guide card for our full Engine Match Guide
  • BUILT TO RUN TRUE — Each QRONQIT shaft is verified for true rotation before shipping, helping maintain smooth, consistent honing motion through the bore
  • GET THE CROSSHATCH RIGHT THE FIRST TIME — Run at 300–500 RPM with honing oil or 30W motor oil only, keep the hone moving in smooth up-and-down motion, and never stop spinning inside the bore. A step-by-step guide card is included with RPM, lubrication, cleaning, and result checks
  • WORKS WITH YOUR REBUILD — Ring material and required surface finish should follow the ring manufacturer's specifications. This hone is designed for cylinder deglazing and crosshatch preparation
  • PART OF THE ENGINE REBUILD SERIES — QRONQIT builds tools for people who rebuild engines, not just sell parts. Every box ships with a setup guide, engine match reference, and direct support contact — because the right tool only matters if you also know how to use it correctly
