About the TPU Top Caps:

Engineered to seat on top of the leaf spring, the TPU top caps serve as a cushioned interface between your mounting hardware and the spring pack. The flexible TPU material dampens impact loads and allows greater suspension articulation without compromising structural integrity — keeping your components protected and your suspension moving freely through technical terrain.

Materials:

• Shims: PETG
• Top Caps: TPU
