New EVP Tapp Clutch Updates (2024): Don't think a TAPP clutch can be any smoother and more responsive than it already is? Think again. The all-new Roller Spider design for TAPP Primary Clutches replaces the original button spider assembly for an instant power delivery due to the reduction in friction between the spider and movable sheave. This results in even better belt grip than before, lower belt temps, better belt life, and buttery smooth engagement that's guaranteed to keep your car dialed in any riding condition. The patent-pending TAPP Roller Primary Clutch is the next revolution in clutching technology.

All EVP Spec TAPP primary clutch kits include full standard weight kit as well as tungsten TAPP Clutch Race Weights (set of 8).

Running a non-EVP tune and still want to enjoy all the benefits and performance of an EVP.MOde Spec TAPP primary clutch? No problem! TAPP clutches are renowned for being incredibly easy to tune and adjust. RPM engagement can be increased simply by flipping the ramps from side A to side B. Flipping two ramps to side B will increase engagement by 600-800 RPM, flipping all four ramps to side B can increase engagement even higher. Additionally, the adjustable clicker bolts can raise or lower engagement by 50-RPM increments for further fine-tuning.

Updated Features:

• Roller Spider Design: creates less friction in the movable sheave compared to button spiders for a much more responsive setup
  
• Center Bearing: NEW black nitrate coating (black finish) adds an extra layer of hardness, prevents rust corrosion, and reduces friction for even smoother clutch operation
  
• Larger Roller: roller size has been increased from 2mm to 3mm, making a huge difference in longevity of the clutch bearing particularly under high horsepower and harsh conditions
  
• Post: updated with additional material and new heat-treating process, allowing the clutch to be over-torqued from factory specs by preventing the clutch from slipping on the shaft (necessary for high-horsepower builds and/or drag racing setups)
  
• Moveable Sheave: added material with the new roller spider design, reinforcing the clutch towers for greater load-bearing capabilities
  
• Clutch Cover: the billet aluminum clutch cover now features larger "windows" to allow additional weight without having to modify the clutch cover

Original Features:

Make your RZR Pro R reach its full potential with the smoothest, quietest, and most responsive primary clutch available. After amazing results running TAPP primaries on all EVP Sand Outlaws Series race cars this season, we're stoked to now offer this bulletproof setup for the powerful Polaris RZR Pro R platform. With calibrations available for the EVP Stage 1-3 ECU tuning package as well as stock-tuned Pro R's, coupled with the insanely convenient adjustability of a TAPP primary clutch‚ this is the ultimate bolt-on-and-ride upgrade to get the most out of any power level.

EVP Spec TAPP Primary Clutches are calibrated for use with the stock secondary clutch, reusing the OEM primary clutch bolt with the included TAPP spacer for installation. EVP calibrated TAPP clutches are the most fine-tuned, responsive and dependable Polaris Pro R primary clutches available. Experience throttle response that pins your back to the seat, responsive power put down via excellent belt grip, plus cooler clutch operating temps for enhanced belt and clutch life.

• Durable Performance: Designed with the durability that high-horsepower UTV's demand, TAPP clutches are built from billet aluminum and other high-tech materials that can withstand extreme heat and extend clutch life, so you can spend more time riding and less time in the shop. EVP has used TAPP clutches on our all-out drag race Can Am X3 and Polaris XPT vehicles with very high engagement launches without failure. The OEM primary clutch is reliable up to about 300 hp, but an EVP Spec TAPP primary can easily handle anything from 200-500+ hp and all terrain and riding styles - drag race, duning, trail riding, rock crawling, short course and desert racing - all with the unrivaled quality, durability and performance expected out of a TAPP Clutch.
  
• Adjustable & Versatile: TAPP clutches are a game-changer when it comes to tuning and adjustability, allowing your clutch to easily evolve as your UTV's power level evolves. The two-sided ramps are swapped in minutes with just an Allen wrench. The clickers are adjusted externally, which can raise or lower the entire shift pattern easily. The roller arms allow mass to be added or removed by removing the clutch cover, and there are a variety of TAPP and EVP primary springs available for fine-tuning. Lastly, the TAPP clutch is also extremely forgiving, allowing a wide variety of helix angles to work with a given primary clutch calibration.
  
• Cooler Temps: TAPP primary clutches run cooler than any clutch on the market. High-tech materials, extensive venting for optimum airflow, and cooler belt temperatures thanks to the multi-angle curved sheaves all contribute to extending belt and overall clutch life‚Äîeven under the most demanding abuse.
  
• Instant Throttle Response: TAPP primary clutches are intended for customers that demand responsiveness and durability from their CVT drive system whether their UTV is relatively stock or all-out big turbo drag race trim. The centralized mass and lightweight, low-inertia design coupled with multi-angled curved sheaves and custom ramp angles deliver unbeatable belt grip, instantaneous throttle response and surefire power to the ground.
  
• Smooth, Quiet Operation: The arms don't 'swing out' like a traditional flyweight but instead ride on a ramp system, which allows the clutch to be remarkably smooth and perform with minimal vibration. You will feel and hear the difference.
