Bore sizing tool AXODE,AX4N

Bore sizing tool AXODE,AX4N Valve has a longer and sturdier spool, eliminating the OE stem and allows a larger contact area with the retainer, preventing the valve from bending or breaking. Annular grooves are added to the spool to properly center the valve and prevent wear. Valve kit includes a replacement spring and retainer. Bore can be quickly and easily resized using the Sonnax resizing tool 96201-BST. NOTE: This valve does not require a reamer. The bore sizing tool restores the original bore. Cause: The spring stem of the OEM valve repeatedly bangs the clip, resulting in damaged bore components and a stuck valve. Correction: Resize the bore with this sizing tool and install the replacement valve with multiple improved features. Used for 96201-16K and SC-AXODE
