TTBOSS-TUN06-ALM – Toytec Aluma Series Boss Suspension System for 00-06 Tundra

Introducing a brand-new addition to our Boss Suspension System lineup.  The Aluma Series Coilovers provide the same great ride quality as our current line but offer additional benefits.

  • Toytec Front Aluma Series Coilovers 
    • The shock bodies are made from hard anodized aluminum for cooler operation as well as better protection from the elements.
    • Adjustable from 2-3″ of lift

    • Coilovers are assembled and ready to bolt on.  No spring compressor or special tools needed for installation.

Durobumps Bump Stops:
