Keystone RRP4498 Driver Side Slip-On Rocker Panel Extended Cab 44 x 6 x 5

The Keystone RRP4498 is a driver side (left side) slip-on style rocker panel designed for extended cab truck applications. Engineered as a collision repair and rust replacement solution, this panel installs over the existing rocker structure without requiring full panel cut-out, making it a practical option for vehicles where the substrate is still structurally sound.

Key Features:

• Slip-On Style: Designed to slide over and clamp to the existing rocker panel — no full replacement welding required in most applications
• Extended Cab Fitment: Sized and shaped specifically for extended cab configurations, which feature a longer rocker section than standard cab trucks
• Driver Side (Left Side): Replaces the rocker panel on the left/driver side of the vehicle
• Steel Construction: Formed from stamped steel for strength and long-term durability
• Dimensions: 44 inches long × 6 inches wide × 5 inches tall — sized to match OEM rocker panel proportions for a clean, factory-style appearance
• Primed Surface: Ready for body filler, primer, and paint to match your vehicle's finish
