Every high-performance vehicle shares one defining feature – its suspension system. Whether it’s a sports car hugging the asphalt at high speed, a motorbike carving through corners, or a pick-up truck balancing payload with ride comfort, suspension springs determine how the machine responds, handles, and endures.
At Lesjöfors, we engineer custom suspension springs that go beyond standard components. By tailoring spring performance to the exact demands of vehicles and their drivers, we help manufacturers and racing teams, including those operating at the very top level of motorsport, such as Formula 1, unlock new levels of precision, durability, and control.
In this blog, we’ll explore how custom suspension coil springs can dramatically enhance performance, and showcase real-world examples where our products have delivered groundbreaking solutions, from racing circuits to heavy-duty applications.
Optimising Automotive Performance with Custom Suspension Springs
Why Suspension Coil Springs Are Key for High Performance
Suspension coil springs sit at the heart of every performance setup. They absorb energy, stabilise the chassis, and determine how a vehicle interacts with the road surface. The right spring rate and geometry directly affect acceleration, cornering, and braking. For high-performance vehicles or those operating in demanding environments, standard off-the-shelf coil springs can’t always deliver the precision required.
The Value of Tailored Spring Solutions
No two performance vehicles face the same demands. A motorbike built for track racing requires lightweight, progressive-rate springs that balance agility with stability. A pick-up truck working across rugged terrain needs custom leaf spring suspension that can carry heavy loads without compromising driver comfort. Bespoke, made-to-order suspension springs ensure every detail – from material selection to heat treatment – is aligned with the specific performance goal.
What Are Custom Suspension Springs?
Defining Custom Suspension Springs
Custom suspension springs are components designed and manufactured for a specific vehicle, application, or performance target. Unlike mass-produced parts, they are engineered with unique dimensions, rates, and geometries to deliver the exact ride quality and handling characteristics required. Whether in the form of custom compression springs or leaf springs, they are precision-built to integrate seamlessly with existing suspension systems.
Core Benefits of Customisation for Performance Vehicles
- Optimised handling: Sharper steering response and stability under high load conditions. - Increased comfort: Reduced vibration and improved damping control. - Durability: Longer life through advanced materials and fatigue testing. - Application-specific performance: Springs tuned for racing, heavy load, or mixed-use conditions. - Competitive advantage: Tailor-made performance that standard springs cannot match.
Custom Suspension Springs for Sports Cars
Enhancing Handling and Responsiveness
Sports cars demand pinpoint precision. Every spring characteristic, whether it’s stiffness, progression, and rebound control, influences how the vehicle corners, accelerates, and brakes. With custom car suspension springs, Lesjöfors fine-tunes these parameters to deliver ultimate road grip and driver confidence. For performance models, tailor-made springs transform handling without compromising ride comfort.
Meeting the Precise Needs of Sports Car Enthusiasts
From luxury GTs to track-focused coupes, enthusiasts and manufacturers alike turn to bespoke suspension springs for one reason: control. Whether it’s fine-tuning ride height, reducing body roll, or ensuring consistent performance under extreme loads, custom coil spring designs allow each car to perform exactly as intended – much like the exacting standards required in Formula 1 car suspension systems.
Custom Suspension Springs for Motorbikes
Boosting Ride Stability and Safety
On two wheels, suspension is a critical part of ride safety. Custom-built suspension springs help motorbikes remain stable at high speed, maintain grip through sharp lean angles, and deliver consistent performance on varying surfaces.
Lightweight, Durable Solutions for Two-Wheel Performance
Weight is everything in competitive motorbike engineering. Lesjöfors develops custom suspension coil springs that deliver high strength-to-weight ratios using advanced alloys and surface treatments. The result is springs that resist fatigue, maintain performance over time, and give riders the confidence to push their machines to the limit.
Custom Suspension Springs for Pick-Up Trucks
Supporting Heavy Loads without Sacrificing Comfort
Pick-up trucks must be robust enough to carry substantial payloads, yet comfortable enough for daily driving. Custom spring suspension systems in utility vehicles enhance load capacity while retaining ride smoothness.
Tuning Suspension for Diverse Work and Adventure Applications
From construction sites to off-road, pick-up trucks encounter a variety of demands. Custom-made suspension springs allow manufacturers to calibrate suspension for mixed-use conditions, ensuring durability, comfort, and adaptability.
Pushing Boundaries – Exceptional Case Studies in Custom Suspension Solutions
At Lesjöfors, we’ve supported vehicle manufacturers and elite racing teams in achieving their performance goals for decades. The following case studies highlight how our engineers have developed custom suspension springs that excel under the most demanding conditions.
For Polestar’s limited BST Edition 270, every component had to deliver elite performance. Lesjöfors worked closely with Polestar engineers to design custom suspension coil springs that sharpened handling, improved chassis dynamics, and matched the vehicle’s high-performance vision. The project exemplified how close collaboration and advanced simulation tools turn design concepts into real-world performance gain.
Öhlins MotoGP Racing – Engineering Firsts at the Pinnacle of Motorbike Suspension
At the highest level of motorcycle racing, suspension is a decisive factor. Lesjöfors partnered with Öhlins to develop tailor-made suspension springs for MotoGP machines. Öhlins needed springs with a linear rate and the lightest possible construction. We developed titanium suspension springs that delivered both, combining advanced engineering with proven craftsmanship to help racing teams gain vital performance advantages.
Pick-Up Trucks – Heavy Duty Springs for the Toughest Loads
Pick-up trucks imported into the UK often face heavier payload demands than their original designs allow. On a recent project, Lesjöfors worked closely with vehicle specialists to develop a custom spring nest that solved recurring weight issues, reduced spring damage, and achieved full type approval for the UK market. The collaboration also led to new suspension solutions for wheelchair-accessible mobility vehicles.
