Sold by the set of 8 only.

Cylinder Sleeve Set (8), LA Sleeve Iron for 90~95 ZR-1 LT5. Manufactured by LA Sleeve.  This Sleeve is finish machined except for the bore which is left undersized at 3.993" to allow for final honing after being installed in the cylinder block to facilitate the use of torque plates.  Torque plates simulate the stresses imposed by the cylinder heads after installation, to obtain the ideal bore size and roundness for better ring performance.  

If LT5 torque plates are not available to you, Jerrys Gaskets has rentals.  Click on this link Torque Plate Set, Cylinder Hone Tool [000] to read more about obtaining LT5 special tools from Jerrys Gaskets.
