Coilover Sleeve Kit
Why You Need Coilover Sleeve Kits?
Coilover sleeve kits provide a cost-effective, modular solution to convert existing standard shock absorbers into a fully adjustable suspension system. They unlock the ability to precisely tune ride height and spring rates to achieve the perfect balance of aesthetic stance and track-day performance.
Enable Precise Ride Height Adjustment
Unlike lowering springs which offer only a fixed drop, the threaded sleeve design allows you to dial in the exact stance you desire corner-by-corner, whether for car show aesthetics or precise track corner-balancing.
Facilitate Easy Spring Rate Customization
The modular design utilizes standard-diameter race springs, allowing you to easily swap springs to tailor suspension stiffness (spring rate) to your specific driving style, vehicle weight, or track conditions.
Lower Center of Gravity for Improved Handling
By significantly lowering the vehicle’s ride height, you reduce the center of gravity, which minimizes body roll during cornering, sharpens steering response, and increases overall stability at speed.
Offer a Cost-Effective Performance Upgrade
They provide the core functionality of a full coilover system—height adjustability and performance spring compatibility—at a fraction of the cost by utilizing your existing, healthy damper struts.
Allow for Fine-Tuning Wheel Fitment and Clearance
The adjustable spring perches help dial in the perfect fender-to-tire gap (wheel gap) and are essential for creating necessary clearance when fitting wider aftermarket wheels and tires.
Our Coilover Sleeve Kits Advantages
DIY Suspension Upgrade
This kit allows you to easily convert standard hydraulic shock absorbers into adjustable coilovers. It’s a cost-effective way to achieve ride height adjustability without buying expensive pre-built coilover shocks.
Universal Fit for Easy Installation
Designed for universal fit, the sleeve slides onto your shock body as long as the diameter matches. No complex welding or fabrication required, making it ideal for DIY installations.
High-Quality Aluminum Construction
Both the sleeve and adjustment rings are made from aerospace-grade aluminum. This lightweight material enhances heat dissipation and is anodized for a sleek, stylish finish.
Secure Locking System
Equipped with dual locking rings or set screws, the sleeve kit ensures that your ride height settings remain secure, preventing any adjustments caused by vibrations during driving.
FAQs
Q1: What is the inner diameter of the coilover sleeve?
The most common inner diameters are 2.0″ or 50mm/52mm. Please measure the outer diameter of your shock body to ensure compatibility.
Q2: Does the kit come with springs?
No, the kit does not include springs. However, we can recommend spring specifications that match the inner diameter (ID) of the sleeve.
Q3: Is this modification safe?
Yes, as long as the snap-ring grooves are correctly processed, this kit offers the same safety and reliability as a factory-made coilover shock.
Q4: Will there be any noise during operation?
To prevent noise, we recommend applying grease or wrapping tape inside the sleeve during installation to eliminate any gaps that could cause noise.
Q5: Are the top hats universal?
We offer top hats with various inner hole sizes, designed to fit different shock shaft diameters for maximum compatibility.
Q6: What payment terms do you accept?
We accept T/T, PayPal (for samples), and L/C for large orders. For new customers, 30% deposit and 70% before shipment is standard.
