McGaughys 2"/4" Deluxe Drop Kit - 1988-1999 Chevy/GMC C2500/C3500

McGaughys' 2"/4" Deluxe Drop Kit is a complete front-and-rear lowering system purpose-built for the OBS heavy-duty platform, giving you a 2" front drop and 4" rear drop with all the correct hardware to keep geometry, ride quality, and durability in check - not just a spring and a prayer.

Up front, the kit uses McGaughys deluxe-spec components matched to your front weight to drop 2" evenly without introducing bump steer or premature wear. Out back, a proper 4" rear drop is achieved with de-arched leaf springs and correct hardware, avoiding the axle wrap and pinion angle issues that plague cheaper "just add blocks" approaches.

This is the deluxe tier, meaning it's engineered for trucks that get driven daily, tow, and haul - not just trailer queens. The kit accounts for the extra weight and different load characteristics of a 3/4-ton or 1-ton truck compared to a half-ton C1500, so you're getting hardware actually rated for your platform rather than an adapted light-duty kit.

Everything bolts to factory mounting locations - no cutting, no notching, no welding. Expect a comfortable weekend install with common hand tools, followed by a front-end alignment. If you're running big brakes or larger wheels, the deluxe components in this kit typically offer more clearance than economy-tier alternatives.

A 2"/4" drop is one of the most popular combinations for OBS heavy-duty trucks because it delivers a genuinely aggressive stance while staying within a range that a quality kit like this can execute without compromising ride quality or introducing excessive negative geometry. Combine with our shock extenders and C-notch if your wheel/tire combo requires additional rear clearance.

This kit is engineered and tested specifically for 1988-1999 Chevy/GMC C2500 and C3500 trucks - don't settle for a C1500 kit stretched to fit your heavier truck's different spring rates and mounting geometry.
