EVP TAPP Roller Primary Clutch Kit for 2016–2021 Polaris RZR XP Turbo/S

EVP TAPP Roller Primary Clutch Kit for 2016 - '21 Polaris RZR XP Turbo/S

DESCRIPTION

NEW EVP TAPP CLUTCH UPDATES (2024):

Roller spider design reduces friction in the movable sheave for faster, smoother engagement and improved belt grip.
Center bearing with black nitrate coating adds hardness, resists corrosion, and lowers friction.
Larger roller increased from 2mm to 3mm for improved bearing longevity under high load.
Post strengthened and heat-treated to prevent clutch slip on the shaft when over-torqued.
Moveable sheave reinforced with added material for greater load capacity.
Billet clutch cover has larger windows to accept extra weight without modification.

KEY FEATURES (CONDENSED):

Calibrations cover stock through EVP Dynomite (DM) and Desert Storm (DS) turbo upgrades.
Calibrated for use with the EVP STM Tuner secondary clutch or OEM secondary with EVP internals (Shift-Tek Helix and Spring).
Kits include a full standard weight kit plus tungsten TAPP Clutch Race Weights (set of 8).
Billet and high-tech materials for cooler operation, better belt life, and durability across riding styles.
Adjustable: swap two-sided ramps, external clickers, and add/remove mass via roller arms.
Smooth ramp-based operation for reduced vibration and quick throttle response.

Disclaimer: EVP Calibrated TAPP primaries may require minor calibration changes. See instructions or contact tech support.

NOTES FOR 2021 XP Turbo/S:

To remove the OEM P90X primary clutch use the EVP Clutch Puller For Polaris RZR Turbo R, Pro XP and '21 XP Turbo/S (P/N 875FP0010).

CALIBRATION GUIDE

There are 4 main adjustable components in an EVP Spec TAPP Clutch:

Ramp Profile — Pre-chosen ramps provided. Changing profile affects shift behavior; recommended only for experienced tuners.
Ramp Angle — Adjust via Quick Shift Bolts. Higher number = higher RPM. Always adjust in pairs across from each other to avoid imbalance.
Roller Size — Supplied with a predetermined size. Available: standard, 1mm oversize, 2mm oversize. Change in pairs; mismatched sizes can cause imbalance.
Weight Adjustment — Use set screws in the arms and washers on the roller thru bolt. Add weight to lower RPM; remove to raise RPM. Adjust evenly in pairs to prevent failure.
