Mounting / fastening material

Secure mounting of suspension systems The correct fastening of the suspension is crucial for the safety of a heavy vehicle. Protempo supplies specific febi U-bolts and bolt sets for mounting air springs on trucks and agricultural vehicles. These parts ensure the spring elements remain firmly clamped to the axle, even under peak loads on the road or in the field. Parts for shock absorbers and leaf springs Besides air suspension, fastening parts for traditional systems are also available. This includes bolts, nuts, bearing bushes, and spacer rings for mounting shock absorbers. We also supply sleeves and covers for leaf spring bushes. Using the correct parts prevents play and ensures the damping continues to work properly. OE-compliant fit and material strength All febi fastening materials, from hex bolts to complete spring plates, comply with the original factory specifications. This means the steel quality and dimensions are exactly correct. As a result, specialist parts like tie rods for level control also fit without modifications, and the required clamping force is ensured. Complete sets for fast repairs Downtime costs money. To speed up a suspension repair, many parts are available as complete mounting and repair kits. This gives the mechanic immediate access to the right bolts, nuts, washers, and sealing rings. This simplifies the work and the vehicle is operational again more quickly.
