Bilstein SLS Series Shock Absorber - Zinc

 

The Bilstein SLS Series Shock Absorber is built for racers who need a sealed steel body monotube damper with straightforward setup choices. It suits motorsports applications where sanctioning rules do not allow or do not require rebuild capability. The zinc plated finish gives the shock a practical race-hardware look while helping protect the steel body.

A 46mm piston and smooth body non-coilover layout keep the SLS Series focused on controlled damping rather than extra adjustment complexity. The design is useful for customers who want consistent fade-free behavior in a simpler sealed package. Standard 1/2in graphite heims support common motorsports mounting needs.

The grouped options include 7 inch and 9 inch standard body versions with multiple linear valving choices. The 7 inch shocks use a 13.15 inch collapsed length and 20.08 inch extended length, while the 9 inch option uses a 14.88 inch collapsed length and 23.52 inch extended length. Customers can match stroke length and valving to vehicle weight, suspension travel, and track conditions.

The SLS Series is a practical option for race cars that need durability and consistent damping without the service planning of a fully rebuildable shock. It can also be converted to a coilover design when the correct kit is used, giving builders flexibility across more than one chassis layout. That makes it useful for racers who want simple hardware with meaningful setup options.

Customers should choose the length and valving based on suspension travel, ride height, and class rules. The available 3-4S, 4-2S, and 5-1.5S options give teams different compression and rebound balances. When the setup is matched correctly, the SLS Series helps the car stay composed through changing track conditions.

Whether customers are upgrading for sealed shock rules, oval-track consistency, or motorsports chassis control, the SLS Series Shock Absorber delivers durable 46mm monotube performance. Now Available at LEER!
