Prothane Transfer Case Mount

Why Prothane Polyurethane Transfer Case Mounts Stand Apart

For four-wheel-drive and all-wheel-drive enthusiasts who demand the most from their drivetrain, the transfer case mount is a component that rarely gets the attention it deserves — until it fails. A worn or stock rubber transfer case mount allows the transfer case to shift and flex under load, introducing drivetrain slop, unwanted vibration, and accelerated wear on surrounding components. That's exactly the problem that Prothane set out to solve with its line of high-performance polyurethane transfer case mounts.

Prothane has been manufacturing performance urethane drivetrain and suspension components since 1991, growing from fewer than 100 part numbers to a catalog of over 10,000 applications — all proudly made in the USA. The brand was founded by car racers and enthusiasts who understood firsthand that factory rubber mounts, while adequate for comfort-focused OEM goals, compromise the stability and responsiveness that serious drivers need.

Polyurethane vs. Rubber: What It Means for Your Transfer Case

Prothane's transfer case mounts are manufactured from their proprietary polyurethane formula — a material that is fundamentally firmer and more durable than the OEM rubber it replaces. Where stock rubber mounts can degrade from heat, oil exposure, and the relentless flex of off-road or performance driving, polyurethane is highly resistant to these forces. The result is a mount that maintains its shape and integrity far longer than rubber, keeping your transfer case properly located and reducing drivetrain vibration transmission to the chassis.

A key advantage of Prothane's polyurethane formulation is its ability to reduce unwanted deflection. When a transfer case mount flexes excessively, it can alter driveshaft angles and stress CV joints and U-joints — especially under the high-torque conditions common in towing, off-roading, or hard acceleration. A firmer Prothane mount keeps everything in alignment where it belongs.

Prothane's Design Touches That Matter

Prothane doesn't just swap materials — they engineer their mounts with purpose-built design features. Their parts incorporate unique construction methods, such as splined bore designs on applicable components, that are engineered to provide years of squeak-free operation. Every Prothane mount that requires lubrication ships with their proprietary Super Grease, specially formulated to work with polyurethane — ensuring proper installation and long service life right out of the box.

Prothane transfer case mounts are available in the brand's signature red or black polyurethane. As with all Prothane products, the color difference is purely aesthetic — performance is identical between the two options, giving builders the flexibility to match their under-vehicle aesthetic.

Backed by a Lifetime Guarantee

Perhaps the most compelling reason to choose a Prothane transfer case mount is the confidence behind it: every Prothane mount carries a lifetime guarantee. This isn't a limited powertrain warranty or a 12-month replacement policy — it reflects the brand's conviction that their urethane products are built to last the life of the vehicle. For a component as critical as a transfer case mount, that kind of backing matters.

Whether you're building a dedicated trail rig, a performance street truck, or simply replacing a deteriorated OEM mount before it causes bigger problems, Prothane's polyurethane transfer case mounts deliver the durability, precision, and peace of mind that rubber simply cannot match.
