More Information

Product Details

The 326POWER Helper Spring Sheets in 70mm ID feature a one-piece aluminum construction at 5mm thick, replacing the conventional three-piece 10mm aluminum collar to expand your helper spring adjustment range. The thinner, single-piece design frees up valuable preload space while maintaining full structural support for the helper spring. Compatible with both 69mm and 70mm ID springs.

Features

  • One-Piece Construction — Stronger and more consistent than conventional three-piece aluminum collars
  • 5mm Thick (vs. 10mm) — Half the height of standard collars, expanding your helper spring adjustment range
  • Dual ID Compatibility — Fits both 69mm and 70mm inner diameter helper springs
  • Available in 6 Colors — Black, Blue, Green, Pink, Purple, Yellow

Note: Sold in pairs of 2 (fits 2 helper springs).

    326 Power Helper Spring Sheets Fitment

    Installed 326Power Helper Spring Sheets between the coilover spring and helper spring on when setting up the coilovers on my Supra. These helper sheets have excellent fit with the 62mm ID coilover springs of my BC Racing coilovers.

    This setup has done 2 autocross events and everything held up well. No rattling, nothing came loose, and pretty solid so far.
