QA1 5Q943-5 Twin Tube Large Body Circle Track Shock 3C/5R Valve

The QA1 5Q943-5 is part of the 5Q Series (formerly known as 51 and 53 Series), a large body steel shock designed for circle track racing applications. This shock features a twin-tube design with a 3C/5R valve configuration (3 compression/5 rebound) and is specifically engineered for front street stock applications. The shock features a black zinc coating that ensures a consistent finish, creating a tight seal every time.

Key Performance Features:

• Scalloped base loop increases clearances in tight areas like upper control arms and shock mounts
• High-quality raw aluminum pistons minimize variations that can be found in anodized parts
• Can be valved with bleed shims or drill out bleeds to maximize tunability
• Upgraded seal kit minimizes leaks, especially in high-rebound applications
• Laser-engraved, black-anodized closure nut makes serial numbers and valving easy to read at the track or in the shop

Easy Maintenance and Rebuild:

• Can be re-valved and rebuilt by racers in minutes using basic tools
• Two-piece bodies make it simple to disassemble and reassemble shocks
• Gland features relief cuts and a hyper screw port, making shocks easy to fill and bleed on assembly
• Compression tube uses a slip fit design to simplify the rebuild process

QA1's steel body shocks can be used in coil-over configurations using the appropriate kits (sold separately). Ideal for Street Stock, Hobby Stock, B-Mod/Sport Mod, and Modified applications.
