EG Hard Gearbox Shell Ver.2  (8mm)

●Complete redesign of the classic version 2 gearbox for AEGs. The EG Hard Gearbox Shell has been designed from the ground up to solve many of the issues of past designs.

●New split panel design makes maintenance and custom builds much easier!

●Quick change spring system and included ball bearing spring guide.

●CNC Aluminium lower panel for the gear set.

●Upper panel for the compression unit.

●Aluminium alloy upper panel and main body.

●Shimming is now faster and easier.

●Labeled shell for quick reference of screw size and part orientation.

●Pre-radiused front and rear.

●Overlapping panels to keep your parts from shifting, and maximising your shimming.

●External wiring, no more pinion gear issues!

●High strength, reinforced main shell passed our 100,000 round test under heavy loads.

●Interior shell is Teflon coated for  easier operation of your gears and compression parts.

●The top portion of the gearbox is now a single piece vastly increasing the strength of the top of the gearbox where most version 2 gearboxes often crack.

    Understandably bit of an expensive gearbox shell… but when you know the reliability and know the additional features that many gearboxes don’t have especially like the quick change spring feature and individual compartments, it really is worth the extra $$
