QA1 5Q94-6 5Q Series Twin-Tube Circle Track Shock Large Body 9in Stroke 4C/6R Bearing Mount

The QA1 5Q94-6 is a large-body, twin-tube circle track shock absorber designed for serious circle track racers who demand consistent performance and trackside tunability. Featuring a 9-inch stroke with 4-compression / 6-rebound valving and eyelet bearing mounts on both ends, this shock delivers predictable, repeatable handling lap after lap.

Key Features:

• Twin-tube, large-body steel construction with a 2-1/16" body diameter for durability and performance
• 4C/6R valving (4 compression, 6 rebound) — 24.30 in. extended length
• Eyelet bearing mounts (Eye-B/Eye-B) for positive, precise suspension linkage
• Rebuildable and re-valveable in minutes using basic tools — no special equipment required
• Two-piece body design simplifies disassembly, rebuilding, and reassembly at the track
• Hyper screw port gland with relief cuts makes filling and bleeding easy during assembly
• Slip-fit compression tube streamlines the rebuild process
• Upgraded seal kit minimizes leaks, especially in high-rebound applications
• Raw aluminum pistons eliminate variances associated with anodized components
• Laser-engraved, black-anodized closure nut keeps serial numbers and valving data readable at the track
• Black zinc-coated body provides a consistent finish and tight seal
• Scalloped base loop increases clearance around upper control arms and tight shock mount areas
• Coilover compatible with appropriate QA1 kits (sold separately)
• Suitable for Street Stock, Hobby Stock, B-Mod/Sport Mod, and Modified class applications

Formerly known as the QA1 51 and 53 Series shocks, the 5Q Series is a proven platform for dirt and asphalt circle track racers. Valving is adjustable via bleed shims or by drilling out bleeds for maximum tunability. Rebuild and re-valve kits are available separately, making the 5Q94-6 a cost-effective, long-term investment for any racing program.
