About Viking Performance

Viking Performance, Inc. specializes in high-performance double adjustable shock absorbers and related products. Founded in 2011 by experienced racing enthusiasts, the company identified a gap in the market for affordable double adjustable shocks, allowing customers to optimize their vehicle's ride quality by independently tuning compression and rebound settings. By focusing solely on these products, Viking keeps prices competitive with single adjustable shocks, offering better performance without unnecessary costs.

Viking conducts all aspects of design, research, and manufacturing in-house, ensuring quick responses to market changes. The company has received prestigious awards like SEMA's Best Engineered Award and has expanded its product line to include various shock types, such as patented race-only Crusader shocks and lightweight aluminum struts. With a commitment to value and quality, Viking aims to provide exceptional products for racing and performance enthusiasts at accessible prices.
