Rough Country 3.5 Inch Lift Silverado: A Deadline-Driven Install Checklist

If you're about to put a lift on a Silverado and there's a date on the calendar—a trail trip, a scheduled inspection, a customer pickup—this checklist is for you. It is not the full factory service manual. It is the six checks I run before turning a single bolt.

In my day-to-day role coordinating installs for an off-road accessory shop, I'm usually the one taking the call after a plan has already gone sideways. When I first started, I assumed the lift itself was the risky part. It isn't. The risk is everything around it: wrong part numbers, missing sockets, a winch cable that only rubs after everything is tight, and that first wash that does more harm than good. Here's the order I trust when there's no time to waste.

1. Confirm Fitment Before Opening the Box: “Rough Country 3.5 Inch Lift Silverado”

The product page may say “Rough Country 3.5 inch lift Silverado” clearly. That gets you close. It doesn't get you to the finish line. You still need to verify model year, 2WD or 4WD, and whether the truck already has any lift or leveling components. Silverado suspension parts are not universal across all generations, and the cost of guessing wrong is usually a full week of downtime while you wait for the right brackets.

Take the extra minutes to check the VIN against the vehicle fitment list on the official product page. Write the part number on a piece of painter's tape and stick it to the box. When you're covered in grease at the end of the day, that tape will tell you what's supposed to be in the box.

2. Get Your Socket Set Ready Before You Need It

I used to think people who obsess over socket sets were just justifying tool purchases. Then I spent an afternoon working with a set that was missing a deep 21mm socket. Since that day, I check sockets first. Suspension work is metric-heavy. For a lift install like this, you'll want six-point sockets, not 12-point, in sizes from around 10mm up to 22mm or 24mm.

If you already own a 3279AM socket set or a similar metric set, verify the sizes and condition before the install starts. If you're shopping, don't just grab the first kit that appears. Look at the breakdown. Does it include deep well sockets? Is there a 21mm? The model number matters less than the actual contents. Also get a breaker bar and a torque wrench. No socket set will fix a bolt that was over-tightened by an impact gun and now refuses to move.

3. Don't Torque Suspension Bolts While the Truck Is Hanging in the Air

Conventional wisdom says torque everything before lowering the truck because it's easier to reach. Everything I've seen in a real shop says otherwise. When you torque control arm bolts, sway bar links, and shock mount bushings with the wheels hanging, the bushings end up twisted when the truck settles at ride height. That causes clunks and short bushing life.

Use a jack to raise the lower control arm until the truck's weight is on it, then do the final torque. If the kit's included instructions say to do it differently, follow the instructions. Most people miss the sway bar links. They tighten those in the air, then call a week later about a popping noise that only happens when pulling into a driveway.

Before calling the lift done, visually check every brake hose, ABS wire, and vent line. Cycle the steering lock to lock and confirm nothing stretches or rubs. This is the boring part of the job, but it's also the part that catches problems before a road test does.

4. Test-Fit the Rough Country EXO Winch Mount Before You Wire the Winch

When you add a Rough Country EXO winch mount, be prepared to test fit before you commit. A winch mount can be bolted on correctly and still have the clutch lever too close to the grille, the winch line off-center, or the control pack in a spot that gets hit by debris.

Place the winch on the mount with the fasteners only hand-tight. Check all the clearances. Rotate the clutch handle by hand. Pull some line off the drum and confirm it lines up with the fairlead. If the mount includes a skid plate or accessory bracket, install those in the dry fit too. Don't assume that because the main holes line up, everything else will.

In March 2024, I was triaging a same-day winch install and we skipped the dry fit because the customer was leaving early the next morning. Everything looked right until the control cable sat against the frame and started wearing after some vibration. We had to pull the mount, reroute the wiring, and reinstall. The mount was fine; our process wasn't.

5. Install a Dash Cam Before the Test Drive

This step feels unrelated to a lift kit, but it belongs in the same work session. After a suspension change, you're going to do more test driving than usual in a truck that may not feel fully settled. If a new noise shows up or a warning light flashes, a dash cam gives you a record of what happened on the road. It also gives you something to review when diagnosing an intermittent issue later.

If you search “dash cam top rated” before buying, you'll get lists that change every few months. Don't let that stop you. Pick a well-reviewed camera, mount it behind the rearview mirror, and wire it to a fuse that only has power when the truck is running. Set the date and time before you mount it and test the memory card. The best dash cam in the world is useless if the footage has the wrong date and the lens is aimed at the wiper blades.

I'm not an electronics installer, and I don't pretend to be. If someone asks me for the “dash cam top rated” answer, I'll point them to a specialist rather than guess. That's the same reason a good suspension shop won't tell you that every accessory category is its strongest category.

6. First Wash: “What Soap Do U Use To Wash A Car?”

This question shows up in my DMs almost every time someone posts a newly built truck. It usually comes exactly like this: “what soap do u use to wash a car?” People expect some specialty off-road product. The answer is more boring: use a real car wash soap, not dish soap.

After an install or an off-road trip, the undercarriage holds mud, road grime, and metal dust. Dish soap is made to cut grease, and it will strip wax and sealants that you want protecting the finish. Use a pH-neutral automotive soap, a clean microfiber wash mitt, and a separate mitt for the wheels and lower panels.

If you have ceramic coating or paint protection film, ask a detailer before you wash. That isn't my job and I won't pretend it is. My advice from an installer's perspective is more basic: keep the pressure washer away from the winch control pack and electrical connectors. Spraying off mud is good. Blasting water into a sealed electrical component is not.

The Last 10% Most People Skip

Before you call the build complete, run through these final checks:

• Get an alignment. A lift kit changes suspension angles, and an alignment is not optional.
• Re-torque after the first 50 miles. I want to say most kits say 50-ish miles, but don't quote me—check what came in the box.
• Test the winch under load, not just in free-spool. The last thing you want is to find out the mount has a clearance problem while you're stuck off-road.
• Keep a written record of part numbers and install date.
• Check local regulations for lift height, winch projection, and bumper rules. Don't rely on a forum post from some other state.

A vendor that tells you which jobs belong to a specialist is more useful than one claiming to handle every category equally well. My lane is making sure the suspension work is tight, the Rough Country EXO winch mount is safe, and the first wash doesn't undo the work you just did. Start with a part number, verify fitment, and use this checklist as your backup plan.
