Before You Begin: Tools, Materials, and Safety

Installing a suspension lift on a Chevy Silverado is a substantial mechanical project that transforms the truck’s off-road capability and stance. Whether you’re planning for larger tires or simply want a more aggressive look, proper preparation and understanding of the process are essential. This guide provides a detailed, step-by-step approach while highlighting trusted brands. Before starting, review your specific lift kit’s instructions, as variations exist between manufacturers and model years.

Gather the following tools and materials before lifting the vehicle:

  • Socket set with metric and SAE sockets (deep sockets recommended)
  • Combination wrenches (typically 15mm, 18mm, 21mm, 24mm)
  • Torque wrench capable of reading up to 250 ft-lbs
  • Floor jack (at least 3-ton capacity) and four jack stands
  • All-thread or threaded rod to aid in compressing/aligning suspension
  • Breaker bar or impact wrench
  • Ball joint separator or pickle fork
  • Grease gun with high-temperature chassis grease
  • Penetrating oil (e.g., WD-40 or PB Blaster)
  • Safety glasses, mechanic’s gloves, and hearing protection
  • A sturdy workbench and clean rags

Safety is paramount. Always work on a level concrete surface, engage the parking brake, and chock the rear wheels. Never rely on a jack alone—use jack stands rated for the vehicle’s weight. Wear safety glasses to protect against debris and fluids.

Understanding Lift Kit Types for the Silverado

Before diving into installation, it’s important to know which type of lift you’re installing. Chevy Silverado lift kits fall into two main categories: leveling kits and full suspension lifts. A leveling kit raises the front of the truck to match the rear, typically using spacer blocks on top of the strut or torsion bar keys. A full suspension lift replaces multiple components (control arms, knuckles, springs, shocks) to increase ground clearance and suspension travel substantially. Full lifts often require additional modifications like longer brake lines, a drop pitman arm, and a rear axle track bar relocation bracket.

For most full lifts (4 inches and up), the steps below are representative. However, always defer to your kit manufacturer’s specific instructions, as bolt locations and hardware differ between brands and model years (2007-2013 Classic, 2014-2018, 2019-current). The following guide assumes a typical knuckle-and-strut spacer-style lift for the front and a block-and-shock lift for the rear.

Step 1: Vehicle Preparation and Front End Disassembly

Begin by removing the front wheels. With the Silverado lifted and secured on jack stands under the frame rails, loosen the lug nuts before jacking. Use a breaker bar or impact gun. Remove the wheels and set them aside. Clean any rust or debris from the hub mounting surfaces.

Next, disconnect the sway bar end links from the lower control arms. Use penetrating oil on the nuts if they are seized. The sway bar can be moved aside but need not be fully removed unless specified by the kit.

Remove the front shock absorbers. For coil-over shocks, use a spring compressor to safely remove the coil spring before disassembly. For trucks with separate coil springs and shocks, remove the lower shock bolt and upper bracket bolts. Be cautious of spring tension. Label all hardware if your kit uses different fasteners for reinstallation.

Unbolt the steering tie rod ends from the steering knuckle using a tie rod separator. This allows the knuckle to be detached later. If your lift kit includes a dropped pitman arm or tie rod ends, now is the time to remove the existing components.

Step 2: Remove the Lower Control Arms and Knuckles

Support the lower control arm with a jack to relieve tension. Remove the lower ball joint nut and separate the ball joint from the knuckle using a pickle fork or ball joint separator. Repeat for the upper ball joint if required by your kit. For full lifts that replace the upper control arm, unbolt the upper arm from the frame crossmember. Remove the knuckle assembly.

On models with torsion bars, release the torsion bar tension by backing off the adjusting bolt, then slide the bar out of the lower control arm. Mark the torsion bar position relative to the key for reassembly.

Inspect the removed components for wear. While the suspension is apart, consider replacing ball joints, bushings, or wheel bearings if they are worn. This saves labor later.

Step 3: Install the Lift Kit Components (Front)

With the front suspension disassembled, begin installing the new lift components. Most kits include the following procedures:

  • Upper control arms: If your kit includes new upper control arms with upgraded ball joints or increased articulation, bolt them to the frame. Use the supplied hardware and torque to manufacturer specs (typically 90-110 ft-lbs for frame bolts, 50-70 ft-lbs for ball joint nut). Apply thread locker if recommended.
  • Strut spacers or lift blocks: For kits that reuse the factory strut, install the spacer between the strut top mount and the chassis. Ensure the mounting holes align and use the provided bolts. Torque to specification.
  • Knuckle extensions or dropped spindles: Some lifts use extended steering knuckles that relocate the wheel hub downward. Clean the hub mounting area, install the new knuckle, and torque the ball joint and tie rod nuts. Use new cotter pins if required.
  • Shock absorbers: Install the new longer shocks. Bolt the lower mount to the lower control arm and the upper mount to the frame bracket. Some kits require drilling or relocating the upper shock mount. Do not fully tighten until the vehicle is resting on its wheels.
  • Sway bar end links: Install longer end links to match the new ride height. Attach them loosely; final torque is done at ride height.

Note: Many full lift kits include a differential drop kit to reduce CV axle angle on 4WD models. Install the drop spacers between the front differential mounting brackets and the frame. Torque the bolts to manufacturer specifications (often 120-150 ft-lbs).

Step 4: Rear Suspension Lift Installation

Lift the rear of the truck and support the axle housing with a jack. Place jack stands under the frame near the rear leaf spring mounts. Remove the rear wheels.

Disconnect the rear sway bar end links (if equipped) and the rear shock absorbers. Unbolt the shock lower mount from the axle and the upper mount from the frame. Remove the shocks.

For leaf spring trucks, you’ll install either lift blocks or add-a-leaf springs. Lift blocks are common for lifts 2-4 inches; longer blocks require longer U-bolts. Remove the factory U-bolts from the spring pack and axle. Place the lift block on top of the leaf spring pack (or between the spring and axle if a top-mounted design). Ensure the locating pin aligns with the hole in the spring perch. Install new U-bolts and gently snug the nuts. Torque in a cross pattern to spec—typically 80-100 ft-lbs for 1/2-inch U-bolts.

For add-a-leaf kits, insert the new leaf between the existing leaves and reassemble the spring pack with the center bolt. Tighten to spec.

Reinstall the rear shocks using the new longer units provided in the kit. Some kits require relocating the upper shock mount; drill any holes precisely per instructions. Torque shock bolts to spec after the truck is at ride height.

If your kit includes a track bar relocation bracket (for trucks with rear coil springs, older models), install it on the axle side to center the axle after the lift. Torque to 100-150 ft-lbs.

Step 5: Reattach Wheels, Lower, and Torque

Reinstall the front and rear wheels. Hand-tighten the lug nuts. Carefully lower the vehicle to the ground using the jack. Do not skip this step—suspension components must be at normal ride height before final torque is applied to control arm bushings, sway bar links, and shocks. If you tighten them while the suspension is hanging, the bushings will be twisted and fail prematurely.

Once the truck is on the ground, use a torque wrench to tighten lug nuts to the factory specification (usually 140-160 ft-lbs for Chevy Silverado). Then torque all suspension bolts that require final tightening at ride height. Consult your lift kit’s torque chart; common specs are:

  • Upper control arm pivot bolts: 90-110 ft-lbs
  • Lower control arm pivot bolts: 120-150 ft-lbs
  • Sway bar end link nuts: 40-50 ft-lbs
  • Shock absorber bolts: 60-80 ft-lbs
  • Tie rod end nuts: 35-45 ft-lbs

Apply thread locker (Loctite Blue) to any bolt that may be subject to vibration.

Step 6: Post-Installation Checks and Alignment

With the truck resting at its new height, perform a thorough inspection. Check all hardware for proper torque. Look for interference between suspension components and brake lines, ABS wires, or steering linkage. Extend and retract the steering wheel to ensure full range of motion without binding. Pump the brakes to seat the calipers and check for leaks at the brake lines (if you loosened them). Top off the brake fluid reservoir if needed.

A professional wheel alignment is mandatory after any suspension lift. Lift kits change the toe, camber, and caster angles. Driving with misaligned wheels will cause rapid tire wear and poor handling. Take the truck to a shop equipped to handle lifted vehicles; many alignment machines can accommodate larger tires. Expect to adjust the drag link and steering stops if necessary.

Additionally, check the headlight aim. Lifting the front raises the beam pattern, which can blind oncoming traffic. Many kits include a headlight adjustment guide. If not, park 25 feet from a wall and adjust the cutoffs to the correct height.

Finally, test drive at low speeds in a safe area. Listen for clunks, pops, or squeaks. Recheck torque after 100 miles—new components can settle and loosen.

Selecting a quality lift kit ensures long-term durability and performance. The following brands are well-regarded for Silverado applications:

  • Rough Country – Offers affordable kits from 2-inch leveling lifts to 8-inch full suspension systems. Their official product page includes detailed installation guides and customer support. Rough Country kits are popular for their comprehensive hardware and solid warranty.
  • BDS Suspension – Known for heavy-duty components and a limited lifetime warranty. BDS provides high-clearance arms and nitrogen-charged shocks. Visit their website to see application-specific kits for late-model Silverados.

  • Skyjacker – Offers both budget-sensitive and premium systems, including soft-ride leaf springs and adjustable shocks. Skyjacker’s product line covers lifts from 2.25 to 12 inches.
  • Zone Offroad – A division of BDS, Zone provides value-oriented kits with many of the same design features. Their site lists Silverado-specific components.

When choosing a brand, consider the level of lift needed, your budget, and whether the kit includes shocks, steering modifications, and brake line brackets. Always read reviews from Silverado owners who have installed the same kit on a similar year and drivetrain (2WD vs 4WD).

Final Considerations

Lifting a Silverado is not a one-and-done project. Raising the center of gravity affects handling, so consider upgrading the steering stabilizer and adding a rear track bar if not included. Larger tires may require recalibrating the speedometer and transmission shift points. Use a handheld programmer or dealer scan tool to adjust the tire diameter.

If you’re new to suspension work, consider having a professional mechanic oversee the installation or assist with the most critical torque steps. Mistakes in the steering or brake components can lead to accidents. With careful planning, quality parts, and patience, you’ll end up with a truck that performs confidently on and off the pavement.
