About Len Performance Shocks
Len Performance was born from a passion for off-road riding and a frustration with the status quo. Len Performance Shocks launched at Hay Days 2024 with a clear mission: deliver high-quality, tunable, rebuildable suspension products that make premium-level performance accessible to more riders. Rooted in the Midwest and backed by nearly 40 years of aftermarket parts experience and 30 years of suspension component development, the brand brings serious engineering credibility to every shock it produces.
Built for Riders, Tuned for the Trail
At the core of the Len Performance philosophy is adjustability and ease of use. Every shock in their lineup ships ready to mount right out of the box, yet offers the kind of fine-tuning options typically reserved for high-end race components. Len Performance shock absorbers feature five-click compression and rebound adjustments on ski shocks, with compression adjustment standard across all track shocks as well. Numbered clickers make it straightforward for any rider — from weekend trail cruiser to seasoned competitor — to dial in their suspension without guesswork.
Len Performance reservoir shocks are constructed from heavy-duty aluminum and feature a finned cooling system on the reservoir. This design actively dissipates heat during hard riding, protecting internal components and extending shock life under the most punishing conditions. The anodized dual-ring preload adjusters allow for quick ride-height tuning that locks in and stays put.
Snowmobile & ATV/UTV Coverage
Len Performance's initial product focus was squarely on snowmobiles, with fitments covering major platforms from Arctic Cat, Polaris, and Ski-Doo. Their suspension kits bundle everything needed to upgrade a sled's ride in one convenient package, while their shock absorber kits make it easy to replace or upgrade multiple shocks at once. The brand has since expanded into the ATV and UTV market, bringing the same adjustable, rebuildable philosophy to four-wheel off-road machines.
One of the standout features of the Len Performance lineup is its serviceability. Rather than treating shocks as disposable components, the brand designs them to be rebuilt and revalved. Their shock absorber repair kits supply the seals, parts, and hardware needed to restore a shock to like-new condition — a practical and cost-effective approach for serious riders who log serious miles. Even the brand's snowmobile-specific accessories, like snowmobile ski skins, reflect a dedication to protecting equipment and optimizing on-snow performance.
A Growing Network, A Rider-First Approach
Len Performance has built a distribution network spanning major powersports distributors across the United States and internationally, with authorized service centers in North America providing hands-on support for rebuilds, tuning, and installation. The brand's rapid growth since its 2024 debut reflects just how eagerly the powersports community has embraced an alternative that doesn't compromise quality for affordability.
