2016-Up RZR 900 Stage 2 Lock & Load Kit

The Aftermarket Assassins Stage 2 Lock & Load Kit packages AA tunes on a Power Vision tuner, the AA Stage 2 clutch kit and the AA slip-on exhaust for the 2016 and newer Polaris RZR 900. The factory calibration limits airflow and closes throttle, and the AA tune is set for 100% throttle no matter the conditions.

Why it holds up

• Average gains around 15 HP for low altitude riding in 50 to 70°F weather. Results vary with temperature and altitude
• Throttle by wire limiters disabled and AA timing curve set up for 91 octane with fuel tables built around the AA slip-on exhaust
• Improved mid range fueling for more mid range power and lower cruising temps
• Seatbelt and 2 foot limiters disabled, speed limiter removed (most see 7 to 10 MPH actual top speed gains) and rev limit at 8800 RPM
• Fan on/off lowered to 190/185°F

Fits

• 2016 and newer Polaris RZR 900 Trail, XC and S
• 2015 models use a different secondary and transmission input shaft. Contact us before you order so we can confirm fit.

Good to know

• Select your clutch kit: stock load (stock or 28" tires) or high load (29"+ tires), and keep or remove engine braking.
• Keep EBS: engine braking stays like factory. Most slower pace riders in mud, crawling or very hilly terrain keep it.
• Remove EBS: removes the EBS pocket in the helix and the roller clunk noise. Most faster pace trail riders, racers and dune riders remove it.
• An optional kid mode tune limited to 35% throttle and 35 MPH can be added.
• Power Vision works as a gauge and data logger, reads and erases trouble codes, switches tunes and returns to stock.
