Silverback Advanced Piston Head Installation Guide

This official Silverback video demonstrates the installation of an advanced piston head on the SRS / TAC-41 platform, including removal of the original head, heat-assisted loosening, tightening with a 6 mm pin and 12 mm flat wrench, and later airbrake adjustment. Use this guide when you need to follow the video’s visual sequence or confirm which piston-head version matches the cylinder-head and hop-up arrangement.

What this procedure does

The footage begins by showing the selected airbrake fitted before the advanced piston head when a short tool is being used. It then moves to removal of the original piston head: the secured cylinder is heated with a blowtorch for at least 30 seconds, with the video warning about burns and advising more heat if the head remains too tight. A 6 mm pin and 12 mm flat wrench are used to loosen the original head and later tighten the advanced head.

After full assembly, the video shows that a long 2.5 mm Allen screwdriver allows the airbrake to be changed without reopening the assembly. The official description identifies two versions: SBA-BPH-01 for an “AEG” cylinder head, compatible with SRS and TAC-41, and SBA-BPH-02 for a “GBB” cylinder head, compatible with TAC-41 using a “GBB” hopup. It also lists Viton and POM sealing parts, an NBR 80° damper, stainless steel CNC construction, and no-airbrake, short, medium and long airbrake options.

What the footage makes clear

This walkthrough stays close to the official Silverback source. The expanded notes explain what is visible at each checkpoint, while measurements, compatibility and cautions remain limited to what Silverback actually states.

  • The five checkpoints and the tool sequence are attributed to the visual review observations from the official video.
  • Compatibility, construction, sealing components, mass and airbrake options are attributed to the official video description.
  • No official or automatic English or French subtitle track was available.

01Fit the selected airbrake firstAt this opening checkpoint, the selected airbrake is fitted before the advanced piston head while the short tool is being used. Compare the frame for the airbrake’s position relative to the piston head, then carry that arrangement into the head-installation sequence before moving on to the original-head removal. Video: 00:20 ↗
02Heat the secured cylinderThe secured cylinder is heated with a blowtorch for at least 30 seconds so the original piston head can be loosened. The video specifically warns about burns and says to apply more heat if the head remains too tight. Once this heating checkpoint is complete, the 6 mm pin and 12 mm flat wrench are used at the original head. Video: 01:24 ↗
03Loosen the original piston headThe 6 mm pin and 12 mm flat wrench are now used to loosen the original piston head. The frame should be compared with the earlier heated cylinder: this is the transition from heat preparation to the mechanical removal shown in the footage. After the original head is loosened, the same tool arrangement leads into tightening the advanced head. Video: 01:55 ↗
04Tighten the advanced headThe advanced piston head is tightened with the 6 mm pin and 12 mm flat wrench. At this point, compare the installed head with the earlier original-head position and follow the visible transition into the completed assembly. The later adjustment method depends on reaching this fully assembled state. Video: 02:57 ↗
05Change the airbrake after assemblyAfter full assembly, the long 2.5 mm Allen screwdriver is used to change the airbrake. This confirms the later adjustment route shown in the video rather than reopening the piston-head installation. The footage notes that a longer airbrake increases sound reduction but loses energy, so the visible airbrake choice remains the detail to compare at this final checkpoint. Video: 03:39 ↗
Source-stated cautions
  • The video warns about burns when heating the secured cylinder with a blowtorch.
  • If the original piston head remains too tight, the video says to apply more heat.
  • A longer airbrake increases sound reduction but loses energy.
Checks shown or stated
  • The selected airbrake is fitted before the advanced piston head when using a short tool.
  • The advanced piston head is tightened with a 6 mm pin and 12 mm flat wrench.
  • After full assembly, a long 2.5 mm Allen screwdriver can be used to change the airbrake.
