If you own a Polaris RZR, Ranger, General, or Sportsman — or a Can-Am Maverick or Defender — you already know that the CVT (continuously variable transmission) system is the beating heart of your machine’s power delivery. At the center of that system sits the secondary clutch assembly, also known as the driven clutch. This single component directly governs how your vehicle accelerates, responds to changing loads, and handles engine braking on descents and technical terrain. When the factory secondary clutch begins to wear, slip, or fail, the degradation in performance is immediate and unmistakable: sluggish throttle response, accelerated belt wear, excessive heat buildup, and a loss of the confident, trail-ready power you count on every time you ride. The Mother Clutcher secondary clutch lineup, designed and distributed by Harvey’s ATV Parts out of Nashville, Tennessee, was built specifically to solve that problem. Since 2011, this family-owned brand has been producing OEM-quality aftermarket clutch assemblies that are engineered to perform better than the parts they replace, offered at a price point that doesn’t require a trip to the dealer. With over 34,000 verified customer reviews, a 1-year warranty standard on all U.S. purchases, same-day shipping on most orders, and coverage for virtually every major Polaris and Can-Am platform on the market, Mother Clutcher has earned its reputation as one of the most trusted names in powersport drivetrain upgrades.

What Is a Secondary Clutch and Why Does It Matter?
To fully appreciate what the Mother Clutcher secondary clutch delivers, it helps to understand the functional role this component plays in your vehicle’s drivetrain. Most modern ATVs and UTVs use a CVT transmission that relies on two clutch assemblies connected by a drive belt. The primary clutch, or drive clutch, is attached to the engine crankshaft and initiates the power transfer. The secondary clutch, or driven clutch, is connected to the input shaft of the gearbox and determines how that power is ultimately delivered to the wheels.
The secondary clutch operates in continuous response to the primary. As vehicle speed, engine load, and terrain demands change, the secondary clutch adjusts its clamping pressure on the drive belt, effectively modifying the mechanical gear ratio in real time without any action required from the rider. When the secondary clutch is calibrated and functioning correctly, acceleration is linear and predictable, belt wear is minimized, and the engine operates efficiently across the full speed and load range. When it degrades — whether through component wear, heat fatigue, or the design limitations inherent in many factory-spec parts — the symptoms are obvious and progressive: rough engagement, slipping under load, belt overheating, and reduced braking effectiveness on descents.
The tied-type EBS secondary clutch design used across much of the Mother Clutcher lineup addresses these issues at the component level. By linking the sheave halves in a mechanically coordinated fashion and calibrating the spring and helix combination for the specific vehicle’s power and weight characteristics, Mother Clutcher delivers a more consistent, responsive, and durable secondary clutch experience than most factory alternatives.
The Mother Clutcher Advantage: Why Riders Choose This Brand
Since Harvey’s ATV Parts launched in 2011, the company has grown from a small college-side business into one of the most recognized names in the powersport aftermarket parts industry. That growth hasn’t happened by accident. Several key factors distinguish Mother Clutcher from competitors.
Engineering Quality That Rivals OEM
The most persistent criticism of aftermarket clutch parts is that they fail to match the tolerances and material quality of factory components. Mother Clutcher addresses this directly. Each clutch is engineered to OEM-equivalent or better specifications based on real-world testing using the same vehicles the clutches are designed to serve. The brand’s founder, Harvey, has a hands-on approach to product development that ensures performance claims reflect actual riding conditions rather than idealized lab environments.
Pre-Tuned and Ready to Bolt On
Clutch tuning is one of the more technical aspects of CVT drivetrain maintenance, requiring knowledge of spring rates, helix angles, and weight configurations to achieve optimal performance. Mother Clutcher eliminates this complexity entirely. Every secondary clutch in the lineup ships with springs and helix pre-installed and pre-calibrated for the specific vehicle application. Riders simply remove the old clutch and install the new one — no special calibration knowledge or additional tuning tools required.
Comprehensive Vehicle Coverage
The Mother Clutcher product catalog covers an extensive range of vehicles across major powersport brands. Polaris coverage includes the RZR 570, 800, 900, and 1000 platforms, the Ranger 400, 500, 570, 700, 800, 900, and 1000 series, the General 1000 and XP, and the Sportsman 400, 500, 570, 700, 800, 850, and 1000 XP. Can-Am coverage includes the Maverick X3 Turbo, Can-Am Defender HD9 and HD10, and selected Maverick 1000R variants. For most popular UTV and ATV platforms produced after 2005, there is a direct-fit Mother Clutcher secondary clutch option available.
Industry-Leading Warranty and Customer Service
Every Mother Clutcher product sold within the continental United States is backed by a 1-year warranty, a standard that compares favorably against most competing aftermarket brands. Returns are accepted within 30 days with postage-paid shipping under the Harvey’s ATV Parts return policy, meaning the financial risk of purchasing is minimal. The company maintains a 99.9% positive seller feedback rating across more than 40,000 transactions on eBay and a similarly strong reputation on Amazon. Customer service is available by phone Monday through Friday from 9 AM to 5 PM CST.
Strong Price-to-Value Ratio
OEM secondary clutch replacements for Polaris vehicles routinely cost $600 or more through an authorized dealer. Mother Clutcher secondary clutches typically range from $299 to $475 depending on the vehicle application, representing savings of 30% to 50% compared to the factory option — without sacrificing quality. Bundle packages that combine primary and secondary clutches offer even greater value, with many complete sets available in the $569–$799 range.
Understanding the EBS Tied-Type Upgrade
Many Mother Clutcher secondary clutch products feature what the brand identifies as the EBS Tied-Type upgrade, and this terminology is important for buyers to understand when selecting the correct product.
In a standard factory secondary clutch, the two sheave halves operate with a degree of independence from each other. In a tied-type design, the fixed and movable sheaves are mechanically interconnected, or “tied,” so that they move in a precisely coordinated manner. This coordination results in more positive and consistent clutch engagement during both acceleration and deceleration phases of operation, which in practical terms means smoother power application off the line, more predictable engine braking on descents, and reduced variability in belt engagement across different terrain and load conditions.
The REDUCED EBS variant seen in some Mother Clutcher products represents a calibration choice rather than a design change. Reduced EBS lowers the intensity of the engine braking effect, which is preferred by riders who find full EBS engagement too aggressive on flat or moderate terrain. The standard tied-type EBS configuration is generally recommended for technical, hilly, or varied terrain where controlled deceleration is a priority.
When in doubt about which configuration is best for a given application, Harvey’s ATV Parts customer service team can provide specific guidance based on the vehicle model, typical riding conditions, and any aftermarket modifications that may affect clutch calibration requirements.
Installation Overview
The emphasis on ease of installation is one of the defining characteristics of the Mother Clutcher secondary clutch lineup. These clutches are engineered for direct bolt-on fitment, using the same mounting interfaces and geometric specifications as the OEM parts they replace. No drilling, welding, or custom fabrication is required.
A standard installation on most Polaris RZR or Ranger models involves removing the CVT cover panel, carefully extracting the drive belt from both clutch assemblies, unbolting and pulling the factory secondary clutch from the jackshaft, installing the Mother Clutcher secondary clutch in its place, routing the belt correctly over both clutches, and reinstalling the CVT cover. Most riders with basic mechanical experience complete this process in under an hour. For first-time installers, Harvey’s ATV Parts provides video tutorial content walking through each step in detail.
A quality clutch puller tool is recommended for easier removal of the old clutch, particularly on platforms where the factory clutch may be corroded or seated tightly on the shaft. Many of the bundle packages available through Harvey’s ATV Parts include a puller tool as part of the kit, which adds practical value and saves the cost of sourcing the tool separately.
Where to Buy a Mother Clutcher Secondary Clutch
Mother Clutcher secondary clutches are available through several reliable retail channels. Harvey’s ATV Parts operates a direct website where the complete catalog is available with competitive pricing, the full 1-year warranty, and the company’s trademark same-day shipping service. Amazon carries a broad selection of Mother Clutcher products, many of which carry the Small Business designation and benefit from the platform’s fulfillment infrastructure and buyer protection policies.
eBay is one of the highest-volume channels for Mother Clutcher sales, with Harvey’s ATV Parts operating as a top-rated seller with 99.9% positive feedback. Many listings include a Best Offer option, providing an opportunity for buyers to negotiate a favorable price on higher-value bundle items.
Third-party retailers like Carkart stock selected Mother Clutcher products with additional discount options for new buyers.

Maintenance Tips for Long-Term Clutch Performance
Owning a high-performance aftermarket secondary clutch means committing to a basic but consistent maintenance routine that protects your investment and keeps the drivetrain performing at its best.
Inspect the clutch sheave surfaces, rollers, and spring assembly after every major trail session or approximately every 25 operating hours. Look for belt contact surface wear, debris buildup in the clutch housing, and any signs of spring fatigue or helix deformation. Keeping the clutch housing clean and free of mud and dust is especially important, as contamination inside the clutch housing can cause engagement to become erratic and dramatically accelerate belt wear.
When replacing your drive belt — a routine consumable item that should be changed at manufacturer-recommended intervals — always inspect the secondary clutch at the same time. The drive belt and secondary clutch are interdependent components, and a worn clutch will shorten the service life of even a new belt. Catching clutch wear early reduces overall maintenance costs and prevents more serious drivetrain damage down the road.
