QA1 CK6005 Coilover Sleeve Kit 60 Series 2-1/2in Spring 6in & 7in Aluminum Circle Track

The QA1 CK6005 Coilover Sleeve Kit is purpose-built for circle track racing applications, designed specifically for use with QA1's 60 Series aluminum shocks. This kit provides everything needed to mount a coil-over spring to your existing shock absorber, accepting 2-1/2" (2.5") inside diameter springs and compatible with both 6" and 7" stroke shock lengths. The lightweight aluminum construction keeps unsprung weight to a minimum — a critical advantage in competitive circle track environments.

Kit Contents (components for one shock, application-dependent):

• Aluminum sleeve — lightweight, corrosion-resistant construction
• Spring cap
• Spring seat adjuster nut — allows ride height and spring preload tuning
• Spring cap retainer pin
• Jam nut
• Snap rings
• Wire ties

Each kit supplies all necessary hardware for one shock. Order two kits for a complete front or rear axle conversion. QA1's coilover sleeve kits are an efficient way to convert compatible 60 Series aluminum shocks to full coilover operation, enabling on-the-fly spring changes and precise corner weight adjustments at the track.
