Custom Stabilizer Bar Bushings Manufacturer & Supplier
Eliminate play. Enhance cornering. We engineer custom sway bar bushings that perfectly match your bar diameter and handling requirements.
Precision Fitment
A universal bushing rarely fits perfectly. A 1mm gap can ruin handling response. We machine or mold bushings to the exact micrometer reading of your stabilizer bar.
The “Squeeze” Factor
We engineer a calculated interference fit (typically 0.5mm undersize on ID) to ensure the bushing grips the bar firmly without binding, maximizing the anti-roll effect.
Bracket Matching
Whether it’s a flat base, Omega shape, or custom billet mount, we profile the bushing OD to seat 100% flush in your housing to prevent deformation.
Material & Fitment Specification
| Parameter | Guidance / Options | Notes |
|---|---|---|
| Bar Diameter Range | 10mm – 60mm+ (Custom) | We machine to your exact measured OD. |
| Material Hardness | 70A, 80A, 90A, 95A | 90A recommended for track use. |
| Construction | Solid Ring or Split Design | Split is standard for D-Bushings. |
| Lubrication Features | Internal Grooves / Knurling | Critical for preventing squeaks. |
| Tolerance | +/- 0.2mm (Molded) | Machined parts can hold +/- 0.05mm. |
The Silence of Engineering
Grooved Bore
Internal channels hold waterproof grease, creating a permanent lubrication barrier.
Teflon Lining
Optional PTFE fabric bonding on the ID for a practically maintenance-free, silent operation.
Surface Finish
Smooth machined bores reduce friction coefficient compared to rough cast surfaces.
Material Tuning: Rubber vs. Polyurethane
OEM Rubber (Standard)
- Excellent vibration isolation (NVH)
- Maintenance free (bonded)
- High deflection under load
- Degrades with oil/ozone exposure
Custom Polyurethane (Performance)
- Superior resistance to deflection
- Impervious to oil, salt, and grime
- Tunable hardness (70A – 95A)
- Requires lubrication
Installation & Serviceability
Design matters for the mechanic. We incorporate features that make installation easier and service life longer.
Split Design
Standard for D-Bushings, allowing installation without removing the entire sway bar linkage.
Retention Flanges
Oversized side flanges prevent the bushing from walking out of the bracket during heavy cornering.
Quality Assurance
Material Certs
Full traceability on polyurethane batches.
Hardness Test
Durometer checks on every production run.
Dimensional Scan
Optical measurement of profile geometry.
Common Questions
Can you make metric sizes?
Yes, we manufacture to any metric dimension (e.g., 22mm, 24mm, 33mm) without requiring expensive new tooling for machined parts.
Do you offer solid bushings?
Yes, we can make solid (non-split) bushings for end-links or factory assembly lines.
What grease should I use?
Use a sticky, water-proof silicone or marine grease. Petroleum-based grease can sometimes degrade certain rubbers, though poly is generally resistant.
Do you sell brackets?
We focus on bushings. Brackets can be sourced for large volume orders.
Is poly stiffer than rubber?
Generally, yes. We formulate it to be stiffer to reduce body roll.
Can I get a sample?
We can produce paid prototypes for validation before full production.
Do you have a minimum order?
Yes, typically 50 sets for machined custom parts.
How long do they last?
Polyurethane typically outlasts the vehicle’s remaining life if properly lubricated.
Can you make flat-bottom bushings?
Yes, we match the OD profile to your specific bracket shape (Flat, Round, Omega).
Do you ship to USA/Europe?
Yes, we ship via DHL/FedEx or sea freight globally.
