Made-To-Order Shim Stacks for Powersports & Recreational Vehicle Suspension from Boker’s, Inc.

Many people enjoy the thrill and exhilaration of recreational powersports and put their chosen equipment through the paces. With many using their vehicles in demanding off-road conditions, the suspension systems are subjected to heavy abuse and require components that withstand extreme forces and environments while providing safe, long-lasting performance, and a smooth and stable riding experience. These performance demands require lightweight, extreme durability and high-strength parts and components that offer the highest levels of reliability throughout the most extreme conditions.

Boker’s has over 100 years of experience producing custom stamped components for various off-road applications including the industry-leading range of non-standard washer, spacer and shim sizes. OEMs recognize the unique qualifications, capabilities and industry-leading quality offered by Boker’s, including over 32,000 non-standard washers, spacer, and shim sizes that can be manufactured to exact specifications with no tooling charges.

In particular, valve shim stacks from Boker’s offer unsurpassed surface finishing to accommodate a wide range of recreational, off-road, automotive and industrial applications. Their valve shim stacks feature exact and consistent thicknesses, inside diameters, and outside diameters. Custom shims and washers can be manufactured with outside diameters ranging from .080” to 12” and material thicknesses from .005” to .190” (varies by material) to satisfy virtually any shim stack application, ranging from simple to complex. Additionally, Boker’s custom stamping offerings include flat blanking and piercing in sizes up to 12″ x 12″, complex metal forming in thicknesses that vary by material from .005″ to .190″ and draws up to 3″ deep and 8″ in diameter.

“The recreational vehicle industry is rapidly growing and constantly adapting to riders’ specific needs and changing terrains,” said Tony Kersey, Communications Director. “As design engineers evolve and develop new products and concepts for recreational vehicles, the process will often require custom metal stampings and riders will continue to rely on a robust suspension system.”
