LS Engine Torque / Honing Plate

$275.00 USD

Torque / Honing plate for LS series engine

Categories: ,


Ls series are known to distort when the head is torqued down so it is important to simulate that stress when honing the block in a performance application.

These plate will fit on all LS series engine; LS1 LS2 LS3 LS6 L92 L96 L33 LM4 LY4 LQ4 etc…

They are CNC machined out of 2″ thick 6061-T6 aluminum. Stainless steel insert are included so it can be used numerous time without damaging the mounting hole.

It is suitable for bore up to 4.150″ for those seeking maximum displacement on these engine, but they obviously can be used on smaller bore too.

I can make custom bore for no extra charge, just contact me and we’ll work out the details.

I sell a lot of these plate on ebay with good feedback so this is why I am able to offer them at a good price. 


  • A Honing plate
