5X Racing Spec Miata Coilover Sleeve and Collar Set

Spec Miata Coilover Sleeves

23993479 - 5XRSMCOS

This version of coilover sleeve for Bilstein shocks is the original sleeve and collar kit that Mazdaspeed offered for many years. We were able to locate the manufacturer of them and offer them to you at a lower price than what Mazdaspeed can offer. We also offer another version of these in a reversible design that are a bit longer, and better suited for those who want to build a street-based coilover kit

Kit includes:

  • 4 each - anodized black aluminum adjustment sleeves
  • 4 each - Spring perch adjusters for 2.5" race springs with plastic tipped set screws

  • Availability: Normally in-stock
    Pricing: $150.00

    These are the original coilover sleeve and collars that Mazdaspeed offered with the Spec Miata suspension kits for those looking to preserve the original design of the SM kit. These sleeves are a bit shorter and take up less space on the shock for race-oriented coilover setups that don't need a lot of ride height. We recommend these sleeves for track and race based coilover kits using 2" bodied Bilstein shocks, such as the 1990-2005 Miata Bilstein replacement shocks.
