Give Him the 9 Inches He’s Always Wanted…of suspension travel, of course. The KellTrac S550 Long Travel Drag Coilovers are an industry-first, purpose-built solution for serious S550 drag racers—from high-9s daily bruisers to full-send 7-second setups. These coilovers aren’t just adjustable—they’re dialed in for drag-specific rebound and compression, giving you real control over weight transfer and traction on marginal surfaces.
Key Highlights:
• Massive 9.00" stroke—the longest travel of any S550 drag strut
• Custom KellTrac valving for razor-sharp launch control
• 15"+ barrel springs = softer spring rates, better transfer
• Adjustable damping for different prep levels & power outputs
• Bolt-in design—align it and send it
• Designed to ditch the front sway bar and keep your launch cleanWhether you're looking to tame wheelies or help them happen, this setup adapts to your build and your track conditions.
