Weihrauch HW80 MAXI Tuning Kit

All the benefits of a standard TbT kit, but custom fitted to the supplied genuine Weihrauch Spring.

The spring supplied in the Full Power kit is the FULL POWER EXPORT SPRING, it is HUGE! You will need a spring compressor to fit it in if you use the full length. It will also be EXTREMELY  powerful! If your country has power limits it is likely you will need to reduce the spring to meet them

The reduced power Maxi Kit comes with a shorter spring that will give usually between 12-14 ft-lb as standard. While this is unlikely to be UK legal without adjustment, it is much easier to rebuild and gives a better starting place for power testing.

Each Kit comprises of spring with fitted delrin spring guide with a top hat, slip washer and 2 preload washers. These kits also come with Lithium based Molybdenum Disulphide grease and abrasive paper as well as instructions for fitting kit and piston sleeve.

This kit may increase power, chrono required! Full instructions on spring shortening available in “Instructions”
