Transfer Case Lowering Kit

What Is a Transfer Case Lowering Kit?

When you lift your truck or SUV with a suspension lift kit, the geometry of your entire drivetrain shifts. The axles drop relative to the frame, but the transfer case stays mounted at its original height — creating steeper driveshaft angles that the factory universal joints were never designed to handle. A transfer case lowering kit (also called a transfer case drop kit) corrects this by repositioning the transfer case skid plate lower on the frame, bringing the output shafts back into a more favorable alignment with the front and rear driveshafts.

Why Driveline Angles Matter

Every 4WD drivetrain relies on U-joints and driveshafts operating within a specific range of angles. One of the main areas affected by a suspension lift is the angle of your driveline — that angle at which the driveline goes into the transfer case must be correct, or you can get a growl or driveline vibration. Left uncorrected, excessive angles accelerate U-joint wear, stress the slip yoke, and produce the telltale vibration that makes highway driving uncomfortable. A transfer case lowering kit is typically only required on trucks with 4" or more of lift.

A transfer case spacer lowers the skid plate by putting spacers between it and the vehicle's frame. The spacers can tilt the engine up at the front and angle it downward at the back, which in turn reduces the pressure on universal joints. The result is a smoother, more reliable driving experience both on- and off-road.

What's Included in a Transfer Case Drop Kit?

A transfer case lowering kit comes in handy when you want to move the transfer case to match proper driveshaft alignment. These kits are a worthwhile investment because they include all the bolts, brackets, and additional hardware you need to complete the installation. Most kits are vehicle-specific, ensuring proper fitment for popular trucks and Jeeps, and can typically be installed with basic hand tools.

Top Brands for Transfer Case Lowering Kits

Skyjacker Suspension is the category leader, offering the broadest selection of transfer case lowering kits covering a wide range of trucks, Blazers, and SUVs. Installation of a Skyjacker transfer case lowering kit on a lifted vehicle will help reduce driveline vibrations. With decades of lift-kit engineering behind them, Skyjacker kits are engineered to pair seamlessly with their own suspension systems.

Zone Offroad brings its off-road suspension expertise to the transfer case drop segment. Their kits help reduce or eliminate front driveline vibration from 6" or taller suspension lifts by reducing the driveshaft angles, making them a go-to choice for heavily lifted trucks and classic Chevy/GMC rigs.

Rubicon Express is a trusted name in the Jeep community, known for engineering drivetrain correction components specifically for Wrangler, Cherokee, and Grand Cherokee platforms. Their transfer case lowering kits are designed to work in harmony with Rubicon Express lift systems for a complete, well-matched suspension solution.

Tuff Country Suspension has built a reputation for straightforward, quality suspension components at accessible price points. Their transfer case drop kits carry that same philosophy — simple to install, correctly sized for the job, and built to last in demanding off-road environments.

Daystar is known for precision-molded polyurethane and composite suspension components. Their transfer case lowering kits often utilize durable, corrosion-resistant materials, making them a smart choice for off-roaders in harsh climates or those seeking long-term reliability.

Choosing the Right Kit

The correct transfer case lowering kit depends on your specific vehicle, your lift height, and whether you are retaining the factory driveshaft or upgrading to a longer unit. One way to determine if you need to adjust the angle of a transfer case is to use an inclinometer to measure the angles of your driveline and transmission output. If the angles are too extreme, the vibrations are likely caused by universal joints being stressed or damaged. Always match the drop amount to your lift height, and consult the manufacturer's fitment guide for your year, make, and model before ordering.
