Why Washers Matter in Suspension Mounting | AVID Racing
The Most Overlooked Component in Suspension Systems
When people think about suspension mounting, they focus on arms, heims, bolts, and shocks. Washers are often treated as an afterthought — or worse, left out entirely.
In reality, washers play a critical structural role in suspension mounting. They directly affect load distribution, joint alignment, clamp force, and long-term durability.
This article breaks down why washers matter, what happens when they’re ignored, and why AVID includes precision washers in every suspension kit we build.
What a Washer Actually Does in a Suspension Joint
A washer is not just a spacer or a cosmetic accessory. In a properly designed suspension joint, a washer performs multiple critical functions:
- Distributes clamp load across a larger surface area
- Prevents fastener head or nut from digging into softer materials
- Maintains joint alignment under dynamic load
- Reduces surface damage during torque application
Without a washer, clamp force becomes localized, which accelerates wear and compromises joint integrity.
Load Distribution: Where Washers Do the Heavy Lifting
Suspension components experience cyclic, multi-directional loads — not static force.
Washers help:
- Spread load across tabs, brackets, and heims
- Reduce stress risers at bolt interfaces
- Protect suspension tabs from ovalizing over time
This is especially critical on:
- Chromoly tabs
- Aluminum suspension components
- High-travel UTV suspension systems
A properly sized washer turns point loading into controlled surface loading.
Washers Protect the Suspension — Not Just the Bolt
Bolts are replaceable. Suspension tabs are not.
Without washers:
- Bolt heads can gouge mounting tabs
- Torque values become inconsistent
- Surface deformation leads to joint loosening
Precision washers act as a sacrificial interface, protecting expensive suspension components from long-term damage.
Alignment Matters More Than Most People Realize
Washers also play a role in keeping joints square and aligned.
In suspension mounting:
- Even slight misalignment increases side loading
- Side loading accelerates bushing and heim wear
- Misalignment reduces effective clamp force
Proper washer thickness and diameter help maintain parallel mounting surfaces, ensuring bolts clamp evenly and joints move as intended.
Precision Washers vs Generic Hardware Store Washers
Not all washers are created equal.
Generic washers often suffer from:
- Inconsistent thickness
- Poor surface finish
- Undersized outer diameter
- Unknown material properties
AVID uses precision washers designed to:
- Match the bolt diameter and shank length
- Maintain flatness under torque
- Withstand repeated load cycles
- Integrate cleanly with titanium and high-strength fasteners
This is intentional — not incidental.
Why AVID Includes Washers in Every Suspension Kit
Every AVID suspension kit includes complete, application-specific hardware, including washers.
We do this because:
- Suspension geometry depends on consistent joint interfaces
- Load paths must remain predictable under abuse
- Proper washers reduce long-term maintenance and wear
Leaving washers out to cut cost creates problems later — problems we refuse to pass on to customers.
Precision Hardware Is a System — Not Individual Parts
Bolts, washers, and nuts work together as a system.
Changing one component without accounting for the others:
- Alters clamp force
- Changes load paths
- Introduces wear points
AVID suspension kits are engineered as complete systems, not collections of parts.
Real-World Use: Race Cars and Weekend UTVs Alike
While AVID hardware is validated in racing environments, the benefits of proper washers apply just as much to:
- Trail riders
- Dune cars
- Recreational UTVs
- Long-term ownership builds
Durability, serviceability, and reduced wear matter whether you’re racing or riding on the weekend.
Frequently Asked Questions
Are washers really necessary in suspension mounting?
Yes. Washers play a direct role in load distribution, alignment, and long-term durability.
Can I reuse old washers?
Reusing washers can introduce uneven surfaces and compromised clamp force. Washers should be replaced when hardware is serviced.
Do washers affect torque values?
Yes. Washers help ensure torque is applied consistently by reducing friction and surface deformation.
Why does AVID include washers instead of leaving them optional?
Because suspension mounting is structural. Leaving washers out compromises the system.
Final Thoughts: Small Parts, Big Consequences
Washers may be small, but their impact on suspension performance is significant.
Ignoring them leads to:
- Accelerated wear
- Inconsistent torque
- Damaged suspension components
Including them — correctly — leads to reliability, longevity, and predictable performance.
