The NEW Race Tech WP Nitrogen Charging Tool works on 2022.5 and later WP shocks with a 74mm OD reservoir.
It can be used on 48 thru 65mm reservoirs with the use of Adapter Bushings, sold individually or in a set.
SET - TSNC-W74PBS
48MM - TSNC-W74PB48
52MM - TSNC-W74PB52
58MM - TSNC-W74PB58
65MM - TSNC-W74PB65
This tool is quick and easy to use and a "must have" if you work on a higher volume of WP shocks. It has clearance for the preload adjusting collar so there is no need to get it out of the way.
