Yamaha Raptor 125/250 DC-4 A-Arm Kit


Description

The Lone Star Racing DC-4 A-Arm Kit is a serious suspension upgrade built specifically for the Yamaha Raptor 125 and Raptor 250. Constructed from 4130 chromoly steel, these A-arms deliver the strength and rigidity needed to handle aggressive riding without adding unnecessary weight. Available in two width configurations, the DC-4 kit gives riders the ability to dial in their stance and forward placement to match their riding style and track demands.

Featuring quick camber and quick caster adjustment, setting up your geometry is fast and precise - no guesswork, no hassle. The DC-4 kit is designed to use the factory inner pivot tubes at the mounting points, making installation clean and straightforward. Backed by a Lone Star Racing Lifetime Warranty (excluding wear items), this kit is a long-term investment in your quad's performance.


Key Features

  • 4130 Chromoly Steel Construction: Engineered for superior strength and durability under demanding riding conditions.
  • Two Size Options: Choose between +2" width with +0.5" forward placement or +3" width with +1" forward placement per side.
  • Quick Camber Adjustment: Fast, precise camber tuning to optimize tire contact and handling.
  • Quick Caster Adjustment: Easy caster changes to fine-tune steering feel and stability.
  • Long Travel Shock Compatible: DC-4 kit requires long travel shocks - designed to work with compatible aftermarket shock setups.

  • 9.58" Shaft Travel: Provides the full range of suspension movement the DC-4 geometry demands.

Size Options & Which to Choose

This option gives you improved stability and a wider stance while keeping geometry changes conservative - ideal for riders who want a meaningful suspension upgrade without dramatically altering their quad's handling characteristics.
  • +3" Width / +1" Forward: The maximum width and forward placement option, providing the most aggressive stance and the greatest improvement in cornering stability and traction. Best suited for racers and performance-focused riders who want to push the Raptor 125/250 to its limits on the track or trail.
