McGaughys Rear 1"-2" Adjustable Drop Shackles - 1988-1998 Chevy/GMC C/K1500

If you've already dropped the front of your OBS truck and the back end is still sitting proud, McGaughys' Rear 1"-2" Adjustable Drop Shackles are exactly what you need to finish the job. These bolt-in shackles replace your tired factory units and let you dial in a 1" or 2" rear drop right from the driveway, no cutting, no notching, no drama. It's the easiest, most affordable way to level out a lowered stance and get that clean, planted look every OBS guy is chasing.

McGaughys has been building lowering hardware for classic GM trucks for going on four decades, and it shows in the fit and finish here. Each shackle is laser-cut and formed in-house from heavy-gauge steel, then finished with a durable black coating to shrug off road grime and moisture. Because they're adjustable, you get to fine-tune your rear ride height after your springs settle in, something fixed shackles just can't do. Sold as a pair, these bolt straight to your existing leaf spring mounts using factory-style hardware, so a Saturday afternoon and a floor jack is really all you need.

These shackles fit both 2WD and 4WD 1988-1998 Chevy and GMC C/K1500 pickups (McGaughys Part# 33037), making them a great companion to any front lowering kit, whether you're running drop spindles, lowered coils, or a full McGaughys deluxe kit. Pair them with a rear flip kit or C-notch if you're chasing a more dramatic drop, or run them on their own for a subtle, factory-plus stance that still rides great and clears speed bumps without drama.

Ride quality doesn't suffer either. Because the shackle geometry is engineered specifically for these trucks rather than a generic universal part, your leaf spring arc stays correct through suspension travel, so you're not fighting axle wrap or harsh rebound. That's the difference between a shackle that just drops your truck and one that drops it right.

At OBS Revival Parts, we only stock parts we'd run on our own trucks, and this is a staple in nearly every OBS build we see rolling through the shop. Whether you're finishing off a subtle lowered daily or dialing in a show truck stance, these shackles get the rear end exactly where it needs to be, and they'll stay there. Grab a pair, a few hand tools, and get your OBS sitting the way it should.
