Barnett Stinger Clutch Spring Retainer Plate Kit – Harley M8
139.99
ONE CLUTCH UPGRADE. TWO WAYS TO RIDE.
Street comfort or serious horsepower? Why settle for just one?
The Barnett Stinger Clutch Spring Retainer Plate Kit is a high-performance, Bolt-On, clutch upgrade designed for compatible Harley-Davidson Milwaukee-Eight Baggers, Softails, and select 2013–2016 CVO models.
Engineered for improved clutch performance, consistent engagement, and durability under demanding conditions, the Stinger Retainer Plate Kit gives riders the flexibility to tailor clutch spring pressure to their build.
Each kit includes two complete sets of springs:
-
Light Springs: Designed for reduced clutch lever effort and more comfortable everyday riding.
-
Heavy-Duty Springs: Designed for demanding, high-performance applications, including builds rated at 190+ HP/TQ.
From daily street riding to serious performance builds, the Barnett Stinger allows you to change spring configurations as your needs change.
LIGHTER PULL WHEN YOU WANT IT. HEAVY-DUTY SPRING PRESSURE WHEN YOU NEED IT.
Two Spring Options. One Complete Kit.
Not every Harley rider needs the same clutch setup.
A daily rider navigating traffic has different priorities than someone building a high-horsepower performance bagger.
Barnett designed the Stinger Retainer Plate Kit to accommodate both.
Light Spring Configuration — Built for Street Comfort
The included light springs are designed to reduce clutch lever effort, making repeated clutch operation easier on your hand.
Ideal for riders who prioritize:
-
Comfortable everyday riding
-
Stop-and-go traffic
-
Long-distance touring
-
Reduced hand fatigue
-
More manageable clutch lever effort
Heavy-Duty Spring Configuration — Built for Performance
The included heavy-duty springs are intended for applications where additional clutch spring pressure is required.
Designed for:
-
High-horsepower Harley builds
-
High-torque applications
-
Aggressive acceleration
-
Performance bagger builds
-
Demanding street and performance use
Barnett describes the heavy-duty spring option as suitable for 190+ HP/TQ applications.
Actual clutch holding capability depends on the complete clutch assembly, its condition, and the specific motorcycle setup.
YOUR BUILD. YOUR SPRING SETUP.
Engineered for Consistent Clutch Engagement
The Stinger Clutch Spring Retainer Assembly is designed to provide consistent spring loading and reliable clutch operation.
Barnett combines precision-machined components with an optimized spring retainer design intended for demanding conditions.
Key Performance Benefits
-
Improved durability compared with the intended factory component
-
Consistent clutch spring loading
-
Improved clutch engagement characteristics
-
Two spring pressure options
-
Precision CNC-machined components
-
Designed for demanding street and performance applications
-
Direct bolt-in replacement on compatible motorcycles
Whether you're refreshing your clutch or preparing for a performance upgrade, the Stinger gives you flexibility without requiring a completely different spring retainer assembly.
Built for High-Horsepower Harley Applications
When you start increasing horsepower and torque, clutch performance becomes increasingly important.
A properly matched clutch setup needs sufficient spring pressure to maintain engagement under load.
The Barnett Stinger Kit includes heavy-duty springs for riders building more demanding Harley-Davidson engines.
Performance-Oriented Features
-
Heavy-duty spring option for high-output applications
-
Consistent spring clamping force
-
CNC-machined retainer components
-
Designed to handle demanding operating conditions
-
Spring configurations that can be changed to suit the application
IMPORTANT: The retainer kit alone does not guarantee a specific horsepower or torque holding capacity. The complete clutch assembly must be appropriately matched to the engine's output.
Complete Kit — Everything You Need in One Package
Each Barnett Stinger Clutch Spring Retainer Plate Kit includes:
| Component | Quantity |
|---|---|
| Stinger Clutch Spring Retainer Plate | 1 |
| Light Springs — MT-131 | 3 |
| Heavy-Duty Springs — MT-158 | 3 |
| Installation Screws | 3 |
The included spring options allow riders to select the appropriate configuration for their intended use.
No need to purchase separate spring sets to choose between the two included configurations.

Important Fitment Information
Not all Harley-Davidson clutch assemblies use the same spring retainer arrangement.
Installation & Setup
The Barnett Stinger Retainer Plate Kit is designed as a direct bolt-in replacement for compatible clutch assemblies.
Proper spring selection and installation are important for correct clutch operation.
Before Installation
-
Confirm the correct Barnett kit for your motorcycle.
-
Inspect the existing clutch components for wear or damage.
-
Select the spring configuration appropriate for your build.
-
Install the retainer assembly using Barnett's instructions.
-
Follow the manufacturer's required fastener torque and installation sequence.
-
Verify correct clutch engagement and disengagement before riding.
Choosing the Right Springs
Light Springs: Prioritize reduced lever effort for compatible street applications.
Heavy-Duty Springs: Intended for builds requiring increased clutch spring pressure.
Spring selection should account for engine output, clutch condition and the complete clutch assembly.
Professional installation is recommended if you're unfamiliar with Harley-Davidson clutch service.
Why Choose Barnett?
Barnett is a well-known name in motorcycle clutch components and performance drivetrain upgrades.
The Stinger Clutch Spring Retainer Kit combines practical flexibility with performance-oriented construction.
Instead of choosing between two entirely different spring retainer assemblies, riders get both light and heavy-duty spring configurations in one package.
It's a useful upgrade for riders who want to tailor their clutch setup to their motorcycle.
