AFCO 86 Series IMCA Modified Shock Package - Premium All-Around Standard Setup (4 Shocks) | Base Valve Balanced Handling for Versatile Tracks

The AFCO 86 Series is widely regarded as the premium steel shock for IMCA Modified racers who want more than a basic monotube. Unlike the entry-level 74 Series, the 86 features a built-in base valve that gives you precise low-speed damping control, dramatically lower nitrogen pressure, and far better small-bump compliance. The compact bulb-style reservoir is lighter and offers superior A-arm clearance, while the nickel-plated body and universal IMCA-legal plug fill port make it the most consistent, race-proven shock in its class.

This All-Around Standard package is the perfect “set-it-and-forget-it” premium setup for 90% of tracks. It delivers smooth corner entry, excellent weight transfer, and reliable control whether the track stays tacky or burns off.

Package Includes (IMCA-legal steel monotube, base valve, plug fill port, 1/2" shaft):

• Left Front (LF): 7" stroke, 5 compression / 4 rebound valving (e.g., 86-7-5-4)
• Right Front (RF): 7" stroke, 4 compression / 6 rebound valving (e.g., 86-7-4-6)
• Left Rear (LR): 9" stroke, 5 compression / 3 rebound valving (e.g., 86-9-5-3)
• Right Rear (RR): 9" stroke, 4 compression / 5 rebound valving (e.g., 86-9-4-5)

Key Benefits:

• Base valve + monotube design for enhanced grip, feel, and tunability over standard shocks
• Lighter bulb reservoir improves a-arm clearance and reduces unsprung weight
• Promotes balanced handling with excellent tire contact and durability
• Fully IMCA compliant (steel body, universal plug port, claimable)

Compatibility: Standard IMCA Modified chassis (2-link/4-bar). Verify fitment. Pair with coil-overs or springs for full upgrades. Backed by AFCO's 1-year warranty—start as baseline and fine-tune!
