Key Features:

• Large body steel construction with black zinc finish for consistent sealing and corrosion resistance
• Twin tube hydraulic design for reliable performance in demanding racing conditions
• Bearing eyelet mounts on both upper and lower positions for precise suspension geometry
• Two-piece body design simplifies disassembly and reassembly for quick servicing
• Slip fit compression tube and hyper screw port make bleeding and filling easy
• Upgraded seal kit minimizes leaks, especially in high-rebound applications
• Laser-engraved black-anodized closure nut displays serial numbers and valving specifications
• Scalloped base loop increases clearance in tight mounting areas
• High-quality raw aluminum pistons minimize variations for consistent performance
• Compatible with coil-over kits (sold separately)

The 5Q Series (formerly 51/53 Series) can be re-valved and rebuilt by racers in minutes using basic tools and available QA1 tuning kits. Valving can be customized using bleed shims or drilled bleeds to maximize tunability for your specific track and driving style.
