McGaughys 5"-7" Deluxe Drop Kit - 1988-1999 Chevy/GMC C2500/C3500

If you've been chasing that low, mean OBS stance on your heavy-duty C2500 or C3500, this McGaughys 5"-7" Deluxe Drop Kit is the ticket. It's a complete front-to-rear system engineered specifically for the extra weight and different spring rates that 3/4-ton and 1-ton trucks carry compared to a half-ton C1500, so you're not stuck adapting a light-duty kit that squats wrong or rides harsh.

Up front you get McGaughys' deluxe spindles and components dropped to work with your factory torsion bar setup, giving you a clean 5" of front drop without the bump-steer and alignment headaches that come from cheaper drop spindle kits. Out back, the kit brings a proper 7" of rear drop using McGaughys' de-arched leaf springs (or blocks/hangers depending on your exact application), keeping axle wrap and pinion angle in check instead of just slamming the frame onto the axle.

This is the "deluxe" tier, meaning it's built for guys who want to drive the truck every day, not just roll it onto a trailer. Ride quality stays composed, the geometry is correct at ride height, and everything bolts to factory mounting points - no cutting, no notching, no drama. If you're running big brakes or upgraded wheels, the deluxe spindle design also gives you more clearance than the economy version.

Every McGaughys kit is engineered and tested specifically for the GM OBS platform (1988-1999 Chevy/GMC C/K trucks), so fitment is dialed in - this isn't a universal kit stretched to fit. Expect a weekend install with common hand tools, an alignment afterward, and a truck that finally sits the way it should.

Whether you're building a clean daily, a show truck, or a mini-tubbed dually project, this kit is the foundation. Pair it with our shock extenders and C-notch if you're going past what a straight drop clears out back.
