QA1 27A686-2M Monotube Shock Absorber 13.35/22.55 T-Bar/Poly V IMCA Sealed

The QA1 27A686-2M is a stock-mount monotube shock absorber from QA1's 27 Series, purpose-built for IMCA-legal dirt track and oval racing applications. Featuring a zinc-plated steel body and a 46mm hard-anodized piston, the 27 Series delivers the same proven performance platform as QA1's legendary 26 Series while offering updated construction and expanded valving options.

This shock measures 13.35 inches collapsed and 22.55 inches extended, with a T-Bar upper mount and Polyurethane V-style lower mount. The 6-2M valving (6 compression / 2 rebound) provides a firm compression and soft rebound tune ideal for controlling body roll and maintaining consistent tire contact on rough oval surfaces. The unit is IMCA sealed, making it legal for use in IMCA-sanctioned racing classes right out of the box.

Key Features:

• Monotube design — superior heat dissipation and consistent damping vs. twin-tube shocks
• 46mm hard-anodized piston — precision-machined for consistent valving and long service life
• Zinc-plated steel body — corrosion-resistant construction for demanding race environments
• T-Bar upper / Poly V lower mounts — direct stock-location fitment for common race car applications
• 6-2M valving — 6 compression / 2 rebound tuning for oval and dirt track setups
• IMCA sealed — sanctioned and legal for IMCA racing classes
• Collapsed length: 13.35 inches | Extended length: 22.55 inches

The QA1 27 Series is designed for racers who demand reliable, repeatable damping performance within a sanctioned, sealed shock program. Whether you're campaigning a modified, street stock, or hobby stock, the 27A686-2M delivers race-proven QA1 quality at a stock-mount price point.
