The QA1 6Q75 is a professional-grade twin tube large body shock absorber designed specifically for circle track racing applications. This aluminum-bodied shock features a threaded body design that makes it ideal for coilover configurations when paired with QA1 coilover kits.

Race-Proven Design Features:

• Large aluminum body construction provides exceptional heat dissipation and durability
• Twin tube design delivers consistent performance throughout extended race sessions
• Threaded body enables easy coilover spring installation and ride height adjustment
• Scalloped base loop increases clearance in tight areas like upper control arms and shock mounts
• High-quality raw aluminum pistons maximize valving consistency
• Two-piece body design simplifies disassembly and reassembly for maintenance

Tuning and Rebuild Capability:

• Can be re-valved and rebuilt by racers in minutes using basic tools
• Valve with bleed shims or drill out bleeds to maximize tunability at the track
• Gland features relief cuts and hyper screw port for easy filling and bleeding during assembly
• Upgraded seal kit minimizes leaks, especially in high-rebound applications
• Laser-engraved, black-anodized closure nut for easy serial number and valving identification

Formerly part of the 60 and 62 series lineup, the 6Q series represents QA1's evolution in rebuildable racing shocks, offering the performance, consistency, and tunability that serious circle track racers demand. This shock is designed for bearing mount installations and requires separate coilover hardware when used in coilover applications.
