Stinger Drives, Inc

We offer Hard Drive gearboxes, Soft Drive Gearboxes and Experimental Aircraft gearboxes with 1.54, 1.73, 2.09, 2.38, 2.68 and 2.88 ratios. The case of the gearbox is cast from 356 T6 heat-treated aluminum. Our large helical cut gears are heat-treated to ensure durability as well. Our careful assembly process sets the gears at zero lash for quiet running. The gearbox cases can be polished to a chrome. REBUILDS Our gearboxes are known to last for thousands of hours with proper maintenance, but eventually they do wear out. Send us your gearbox and we'll rebuild it from the ground up. A rebuild from us includes: Completely disassembling the gearbox. Thoroughly cleaning and carefully inspecting every part. Bead Blasting the case,(if it's not a polished one), and thoroughly cleaning it again. Carefully polishing the shafts. Replacement of all bearings and seals. Reassembling the case and pressure testing. Reinstalling adapters and drive plate. And of course we carefully box up your gearbox and ship it back to you.
