Description
Tinbum Tuning Maxi UK Drop In Kit HW97/77
All the benefits of a standard TbT kit, but custom fitted to the TbT Premium Spring!
A choice of Full power which gives up to 20j / 15ft-lb, or the new UK spec kit which will give power of sub 16j / 12ft-lb in most cases with the newer 26mm piston, though this is not guaranteed.
The original 25mm piston guns can take either kit, but as the power is naturally sub 12 ft-lb, we recommend the using the Full power kit, reducing the spring if necessary.
Each kit comes with a TbT Premium spring with fitted spring guide and top hat, slip washer and 2 preload washers. This kit also comes 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”
