Budget Kit for Polaris Patriot 850 (Short Track Sleds) // SKU: 13-310-BUDGET-T
⚙️ REQUIRED KIT SELECTIONS: Please configure your kit options using the dropdown menus above:
-
Secondary Clutch Helix Style:
- Standard TSS-4 Helix (SKU: 05-TSS-4): Precision-machined dual-cut billet helix engineered for aggressive shift-out and instantaneous backshift response on high-speed trail systems.
- Lightweight TSS-4C Helix (SKU: 05-TSS-4C): Precision CNC-pocketed design that sheds almost 20% (nearly 18%) of rotational mass to reduce drivetrain inertia and provide faster throttle pickup.
-
Secondary Spring Anti-Binding Hardware:
- Smooth Shift Teflon Washers: Maintenance-free, budget-friendly teflon washers that isolate spring rotation and eliminate binding under compression.
- TSS-04 Secondary Roller Bearing: Premium needle-bearing assembly delivering near-zero rotational friction under heavy load for ultra-fast backshifting and cooler clutch operation.
-
ECU Flash Tuning Delivery:
- ECU Hard Flash (Mail-In): Send your factory ECU to Bikeman Performance for in-house bench flashing and immediate return shipping.
- Torque Link Pro Tuning Device: Handheld flash tool allowing you to flash custom tunes at home, switch maps, view live telemetry, and read/clear diagnostic codes.
SKU: 13-310-BUDGET-T
Primary Application: Polaris Patriot 850 short track, trail, and crossover snowmobiles (Indy, Indy VR1, Switchback Assault 146, and XCR platforms).
Unlock an honest +10 to 12 HP and massive mid-range trail grunt on your Polaris Patriot 850 with the Budget Kit. Designed for trail riders looking for serious horsepower gains while retaining the factory stock exhaust muffler, this kit combines our high-flow ceramic-coated exhaust manifold (Y-pipe), dyno-proven ECU digital tuning, and a complete Stage 2 short track clutching system.
The factory Y-pipe and stock clutching choke off exhaust scavenging and create power-robbing belt slippage. By replacing the manifold with our high-velocity ceramic Y-pipe, re-mapping fuel and ignition curves, and installing our Stage 2 SNYPR trail clutching package featuring your choice of standard or lightweight TSS-4 helix, you get instant throttle snap, lower exhaust gas temps, and relentless corner-to-corner trail acceleration.
Key Performance Features
- +10-12 HP Dyno-Proven Gains: Increases horsepower and mid-range torque without changing the factory exhaust sound or adding decibels.
- Ceramic High-Flow Exhaust Manifold: Smooth internal transitions maximize exhaust gas velocity and scavenging, lowering cylinder head temperatures on sustained hard pulls.
- Custom ECU Digital Tune: Precision-engineered fuel mapping, ignition timing curves, and raised rev limits delivered via ECU Hard Flash or the Torque Link Pro handheld device.
- Rotational Mass Reduction Option: Choose the lightweight TSS-4C helix to cut secondary rotating weight by almost 20% for razor-sharp throttle response out of corners.
- Stage 2 Trail Clutching: Includes SNYPR magnetic adjustable weights, custom 850 trail helix, 120-310 primary spring, 140-220 secondary spring, and small rollers to put full horsepower to the track.
- Customizable Anti-Binding Performance: Choose between low-maintenance Teflon Washers or high-performance TSS-04 Needle Roller Bearings to eliminate secondary spring binding and lower belt heat.
Critical Fitment & Roller Compatibility Note
⚠️ IMPORTANT OEM CLUTCH ROLLER FITMENT NOTE: Both the standard and lightweight secondary helix options in this kit require small secondary clutch rollers for bind-free operation.
Polaris introduced a larger OEM secondary roller on select models beginning in 2021. These larger factory rollers are NOT compatible with this helix profile. This kit includes our Small Secondary Clutch Rollers (TP-460079K) to ensure seamless conversion, bind-free helix operation, and optimal performance on all 2021+ models.
