If you've lowered your OBS truck, you've probably realized that an 88-98 chevy rear shock relocation kit is pretty much a necessity if you want to stop your spine from rattling every time you hit a pebble. Anyone who's spent time in the world of C1500s or Silverados knows that these trucks look killer when they're sitting low, but the factory shock geometry is a total nightmare once you start pulling out leaf springs or adding flip kits. It's one of those modifications that doesn't look like much in a box, but it completely changes how the truck feels on the road.
Why the Stock Setup Fails When You Lower the Truck
The engineers back in the late 80s and 90s weren't exactly thinking about us slamming these trucks to the ground. They designed the rear suspension for work—hauling mulch, towing trailers, and absorbing big bumps with plenty of travel. In a stock setup, the shocks sit at a pretty drastic angle. When the truck is at its factory height, that angle works fine. But as soon as you drop the rear four, five, or six inches, everything gets out of whack.
When you lower the rear, you're basically eating up all the "stroke" of the shock. The shock ends up being almost fully compressed just sitting in the driveway. Then, when you actually drive it, there's nowhere for that shock to go. It either bottoms out instantly or, because of the weird angle it's now at, it doesn't really "dampen" anything at all. You end up with that classic OBS bounce where the back of the truck feels like it's on a pogo stick. That's exactly where an 88-98 chevy rear shock relocation kit comes into play.
How the Kit Actually Works
The whole point of a relocation kit is to fix the geometry. Most of these kits move the upper or lower mounting points (or both) to get the shock back into a more vertical position. By standing the shock up straighter, you allow it to actually do its job. Instead of the force of a bump pushing sideways against the shock body, the force goes straight up through the piston.
Most of the kits you'll find on the market are designed to be "bolt-on," though I'll be honest—sometimes "bolt-on" in the truck world means you're still going to be doing a little bit of drilling. The kit usually includes new brackets that mount to the frame and sometimes new plates for the axle side. By moving these points, you can also use a longer shock, which gives you more travel. More travel equals a smoother ride and less chance of that jarring "thud" when you hit a pothole.
The Difference You'll Feel on the Road
I've talked to guys who struggled with their ride quality for years, swapping out different brands of shocks thinking the shock itself was the problem. They'd go from cheap parts-store specials to high-end adjustable units and still complain that the truck rode like a log wagon. The second they installed an 88-98 chevy rear shock relocation kit, the problem vanished.
It's not just about comfort, either. It's about control. If your rear end is bouncing all over the place, your tires aren't staying in contact with the pavement. This is especially noticeable if you're trying to take a corner with some speed or if you're driving on a rainy day. A relocated shock keeps the rear tires planted. You'll notice the "floaty" feeling goes away, and the truck feels much more composed. It's the difference between feeling like you're driving a project that's barely holding together and a truck that was built right.
Choosing the Right Kit for Your Drop
Not all kits are created equal, and you really want to make sure you're getting something beefy. You're looking for thick, laser-cut steel—usually 3/16" or 1/4" thickness. Since these brackets are taking the brunt of the suspension's force, you don't want some flimsy stamped metal that's going to flex or crack over time.
You also need to consider how low you've actually gone. If you're just doing a mild 2-inch drop, you might not need a relocation kit (though it wouldn't hurt). But if you've done a flip kit and you're sitting 6 inches lower than stock, it's non-negotiable. Some kits are specifically designed for trucks with C-notches, too. If you've notched your frame to keep the axle from hitting it, you'll want to make sure the 88-98 chevy rear shock relocation kit you pick out is compatible with your specific notch. Most are, but it's always worth double-checking the clearance.
Installation Real Talk
If you're a DIYer, this is a totally doable weekend project. Most kits are designed to work with basic hand tools, a jack, and some jack stands. However, don't let the "easy" label fool you. You're going to be working in a pretty tight space, especially around the gas tank and the exhaust.
One thing that catches people off guard is the spare tire crossmember. On some 88-98 Chevys, the factory spare tire mount gets in the way of where the new shock brackets need to go. You might find yourself having to cut out a bracket or relocate the spare (let's be real, if your truck is slammed, you probably aren't carrying a full-sized spare under there anyway).
Also, expect to do some drilling. Even if the kit says it uses factory holes, the tolerances on these old trucks can be a bit creative. Having a good set of cobalt drill bits and a high-torque drill will save you a lot of swearing. Once the brackets are on, it's just a matter of mounting the new shocks and torquing everything down.
Don't Forget the Shocks
It sounds obvious, but a relocation kit is only half the battle. You can't just take your old, blown-out factory shocks and stick them on the new brackets. Well, you could, but it would be a waste of time. When you install an 88-98 chevy rear shock relocation kit, you usually need to buy "drop shocks" that are valved for a lowered ride height and have the correct extended and collapsed lengths for the new mounting points.
A lot of guys go with something like a Belltech Street Performance or a QA1 adjustable if they have the budget. The adjustable ones are great because you can actually "tune" the ride. If you like it stiff for the track or soft for cruising to a meet, you just click a knob. It's a bit more of an investment, but if you're already doing the work to relocate the mounts, you might as well put the best dampening you can afford on there.
Is It Worth the Hassle?
In a word: yes. If you plan on actually driving your 88-98 Chevy, this is one of the best bang-for-your-buck mods you can do. It's not flashy—nobody is going to see your shock brackets at a car show unless they're crawling under the truck—but you'll appreciate it every single mile you drive.
The 88-98 platform (the GMT400) is one of the best-looking trucks ever made, and they're only getting more popular. Taking the time to fix the suspension geometry with an 88-98 chevy rear shock relocation kit elevates the truck from a "cheap lowered pickup" to a well-engineered street machine. It saves your back, saves your tires, and makes the whole driving experience a lot more fun. Stop putting up with the bounce and just get it done—your spine will thank you.
