SHS reinforced steel gear set for Marui NGRS recoil: spur bevel sector 10 tooth, built for M90–M120 spring loads and reliable gearbox tuning.
SHS reinforced steel gear set for Marui NGRS recoil is a complete 3-gear upgrade built for Tokyo Marui Next Generation Recoil Shock (NGRS) gearboxes. Whether you are replacing worn gears or building a smoother, more dependable drivetrain, this set helps restore clean engagement, consistent cycling and long-term durability in demanding airsoft use.
Each gear is CNC machined from reinforced steel to keep tooth profile accuracy and rigidity under load. On Marui NGRS platforms, tight tolerances and true rotation matter: better mesh can reduce harsh noise, limit premature wear and make your setup easier to tune (especially when you are chasing a stable feel shot after shot).
The kit includes a 10 tooth sector gear, a popular choice for maintaining an efficient cycle while supporting spring loads commonly used from M90 up to M120. Final results always depend on shimming, motor type, battery performance and overall gearbox condition, but a correctly set drivetrain generally runs cleaner and stays reliable longer.
If your replica uses the Tokyo Marui Next Gen recoil system, this SHS gear set is designed for that gearbox family. Always confirm gearbox version, bushings/bearings size and internal wear before installation.
Inside the box you will find the three essential gears: bevel gear, spur gear and sector gear. Replacing the full set is ideal when you want consistent mesh across the train, rather than mixing old and new parts with uneven wear patterns.
For the quietest and smoothest result, shim each gear carefully, ensure free rotation with minimal side play, and apply a thin, suitable grease. After assembly, check motor height so the pinion meshes correctly with the bevel gear, then run brief function tests before extended use.
Because NGRS gearboxes have their own layout and tolerances, take your time to verify engagement and cycling. As a guideline, this set is often paired with M90–M120 springs, but your safe range depends on compression parts, piston condition and overall tuning.
Summary: SHS reinforced steel gear set for Marui NGRS recoil delivers a reinforced steel, CNC-machined drivetrain with a 10 tooth sector gear, suited to maintenance or performance-focused NGRS builds when installed and shimmed correctly.
