Product Description
ICT Billet LS Engine Block Honing Torque Plate
Fits LS Engine Block Honing Applications | ICT Billet 551335 | 1.65" Billet Aluminum Torque Plate with 4.20" Cylinder Holes
Machine LS engine cylinders with greater accuracy using this LS Engine Block Honing Torque Plate. Designed for engine builders, machine shops, and serious LS performance builds, this ICT Billet 551335 torque plate helps simulate cylinder head clamping force during the honing process. By using a torque plate while honing, the cylinder bores can be finished under conditions closer to final engine assembly, helping improve ring seal, cylinder geometry, oil control, and overall engine sealing performance. Built from a 1.65" thick one-piece billet aluminum plate with 4.20" cylinder holes, this torque plate is made in Wichita, Kansas from aerospace-grade, USA-produced billet aluminum for strength, stability, and repeatable machining use.
Key Features & Benefits
- Designed for LS Block Honing: This torque plate is built for LS engine block honing applications where accurate cylinder finishing matters. Using a honing torque plate helps simulate the distortion created when cylinder heads are torqued in place, allowing the bores to be honed closer to real assembled conditions.
- Helps Improve Ring Seal & Cylinder Finish: Proper torque plate honing can help improve cylinder roundness under load, which is important for piston ring seal, compression consistency, oil control, and long-term engine performance. This is a valuable machining step for performance LS rebuilds and high-output combinations.
- 1.65" Thick Billet Aluminum Construction: Manufactured from a solid 1-piece, 1.65" thick billet aluminum plate for strength and stability during machine work. The rigid design helps provide consistent clamping simulation and dependable performance through repeated shop use.
- 4.20" Cylinder Holes: Features 4.20" cylinder openings for LS engine machining applications. This makes the plate useful for common LS bore sizes and performance engine builds where proper honing preparation is critical before final assembly.
- Uses Factory Length Head Bolts or Studs: Designed to work with factory-length LS head bolts or head studs for proper installation during the honing process. This helps simplify setup for machine shops and engine builders using standard LS-style cylinder head fastener lengths.
