Why Choose ICS Trailers

A jaw repair kit needs to match the actual lock system because nearby JSK37 repair kits can contain different locking bars, wearing parts or additional hardware. ICS Trailers can compare the existing JOST reference, fifth wheel model, old components and photos before you order.

• Replace the jaw-related lock components as a matched repair set.
• Use the JOST reference to separate this aftermarket kit from other JSK37 lock kits.
