VRP 20H (JTP) Piston Tekno

This is a set of (4) Patented VRP ‘XV4’ JTP version Shock Pistons (2) 20H F Pistons. These are drilled 4h1.5, 16h.6mm.  The return Holes are 1.1mm. They are lasered with a “F” on them. (2) 20H R Pistons. These are drilled 3h1.5, 1h1.6, 16h.7mm.  The return Holes are 1.2mm. They are lasered with a “R” on them. Tekno NB/EB48 2.2 : R piston in Front, 575 warm - 525 cold temperature : F piston in Rear, 450 warm - 400 cold temperature (recommended oil for inside hole on arms) Tekno NT/ET48 2.2 : F piston in Front, 700 warm - 650 cold temperature : R piston in Rear, 575 warm - 525 cold temperature (recommended oil for middle hole on arms) The pistons are precision drilled on the CnC. Hand drilling this hole pattern does not have the same results. The small holes HAVE to be clean with NO burr, and they have to be straight. Thats impossible to do by hand.  The VRP ‘XV4’ Pistons are designed to have a washer under and over them. It is important to run washers and that they are correctly install
