• M1 Monotube Shock Pair (front) — application-valved N3 series shocks tuned for balanced on and off-road performance.
• M1 Monotube Shock Pair (rear) — matches front shocks for consistent damping across the suspension.
• 6 Inch Coil Box — precision-fit front coil spring perches that bolt to factory mounts for straightforward installation.
