SELECTION
Airsoft Gear Ratio Guide
Compare 18:1, 16:1, 13:1, 12:1, 9:1 DSG, and platform-specific options without relying on one-size-fits-all speed claims.
TECHNICAL RESOURCES
Airsoft Gearbox Guides
Use clear, practical references to compare gear ratios, identify gearbox compatibility, plan installation and shimming, and diagnose common drivetrain problems.

FITMENT
Gearbox Compatibility Guide
Identify V2, V3, SR25, SVD, DSG, and related fitment checks before ordering a drivetrain component.
WORKSHOP
Gear Installation & Shimming
Follow a controlled sequence for inspection, gear positioning, shimming, lubrication, reassembly, and initial testing.
DIAGNOSIS
Gearbox Troubleshooting
Work from symptoms to likely causes while avoiding repeated test cycles that can increase damage.
A RELIABLE PROCESS
Use the guides in three steps
Platform labels are a starting point. Final compatibility depends on the exact component, gearbox shell, surrounding parts, and selected product option.
Identify the gearbox
Confirm the gearbox version, shell, existing gear type, bushings or bearings, and any ETU or mechanical trigger components.
Define the build goal
Decide whether the priority is balanced reliability, response, controlled cycling, torque, or a specialized DSG configuration.
Verify the final specification
Check the individual product description, selected variant, dimensions, tooth count, and installation requirements before ordering.
QUICK ANSWERS
Gearbox guide FAQ
General answers to common questions before you move into a detailed guide.
Can one guide confirm that a part will fit every V2 or V3 gearbox?
No. V2 and V3 describe broad gearbox families, but dimensions, shell design, bearings or bushings, electronics, and other internal parts can vary. Confirm the exact product and selected variant.
Should I choose the lowest gear ratio for the fastest build?
Not automatically. Lower numerical ratios can support faster cycling, but motor torque, spring load, battery, piston setup, timing, heat, and installation quality must work as a system.
When should I use a professional technician?
Use an experienced technician if you cannot safely control the spring, identify damaged parts, verify shimming and motor alignment, or complete a controlled test without abnormal noise, heat, or binding.
