These springs solve common lifting challenges by combining a precise 3-inch elevation with an engineered ride profile that minimizes harshness and noise. The result is improved front-end stance without compromising stability, plus enhanced durability for engines with higher torque or equipment like snow plows. The included bushings and proven EZ-Ride design make installation straightforward and reliable, helping you get the most from your GM 4WD setup.
