These are Raceland Ultimo Coilovers, a high-performance aftermarket suspension system specifically designed for the Infiniti G35 (2003–2008) with the front fork lower mount configuration.
The "Ultimo" line is positioned as a step up from their "Classic" series, offering a more aggressive drop and stiffer spring rates for improved handling and aesthetics.
Key Features & Specifications
• Ride Height Adjustment: Allows for a significant drop of 2–4 inches below the factory stock height.
• Visual Design: Features the signature Raceland lime green powder-coated springs with CNC-machined locking collars anodized in gold.
• Build Quality: The shock bodies are finished in a black zinc plating for added corrosion resistance.
• Components Included: * Two front coilover assemblies with fork-style lower mounts.
• Two rear coilover assemblies.
• Adjustment spanner wrenches (used to dial in the ride height).
Important Installation Notes
The included instruction sheet highlights several critical "Pro-Tips" to ensure the longevity of the kit:
• Tool Safety: Never use pliers or tools on the chrome shock piston rod, as any scratches can damage the seals and void the warranty.
• Seizing Prevention: The manufacturer highly recommends applying anti-seize grease to the adjustment threads to prevent the collars from locking up over time due to road debris or salt.
• Tightening: Use the appropriate wrenches/allen keys to tighten the top mounting nut; avoid over-tightening with impact wrenches which can damage the internal valving.
Warranty
As noted on the packaging, this kit is covered by a Lifetime Warranty, which is a standout feature for entry-to-mid-level coilover kits.
