  • The Dynatrac Hard Core Plus Axle Set Will Save You Up to $2,500

    Most people tell us that they know that the Dynatrac ProRock® axles – and XD60 axles specifically – are the ultimate in strength and durability. There’s no arguing that the patented ground clearance means that our axles give you the best ground clearance. Period. But most people believe that a Dynatrac Hard Core Plus Axle Set™ for the Jeep Wrangler JK, Jeep Wrangler JL and Jeep Gladiator JT is much more expensive than other 60-class crate axle offerings. The reality is that our Hard Core Plus Axle Set may actually save you $2,500 compared to the competitors’. In fact, even if you pay more to upgrade to “the other guys” axles, you still won’t get many of the exclusive features and benefits you’ll find in Dynatrac ProRock XD60® axles. Continue reading

  • Jeep Wrangler JL Transfer Case Modification

    The 2018 Jeep Wrangler JL has many great, new features. It may be the most-capable Jeep Wrangler ever made. We dove right into this new model and built the first JL on 42s, named CODE1. Through our series of modifications which included Dynatrac ProRock axles and 42-inch tall tires, we ran across a situation where the transfer case may refuse to shift; specifically when the front axle is replaced with one that does not have front-axle disconnect (FAD).

    The Jeep JL is equipped with a Magna transfer case. The transfer case uses a synchronizer to smooth shifts between high-range and low-range. Ironically, components of this synchronizer seem to be what keep the transfer case from shifting in certain situations. Continue reading

  • Dynatrac ProRock 44 Track-Bar Mounting Options

    The raised track-bar bracket with steering ram assist cylinder or steering stabilizer mount is an option for any 2007-2018 Jeep Wrangler JK Dynatrac ProRock44 front axle housing. This bracket is recommended for any Jeep JK with a 2-inch lift or higher.

    Track-Bar Mounting Options

    OEM development engineers spent an exorbitant amount of time optimizing the vehicle’s steering linkage geometry at OEM ride height.  When a Jeep JK is lifted, a new ride height is established and the steering linkage geometry is altered.  The new steering linkage geometry results in poor vehicle handling and stability.  In order to restore the steering linkage geometry back to OEM standards, the draglink and track bar bracket mounting positions have to be adjusted. Dynatrac’s raised track bar bracket is designed to work in conjunction with a draglink flip kit to correct the steering linkage geometry.

  • Lance Clifford Chose Dynatrac to Eliminate Axle Worries

    Lance Clifford, founder of pirate4x4.com, has built a lot of 4x4s over the years. From Toyota pickups to race rigs, along with his fair share of Jeeps. When he decided to build his current Jeep JK, the one thing he had learned from all of those other 4x4s was to make the drivetrain bulletproof.

    “I wanted it to not break down. Ever,” Lance said, “I wanted to be able to do any trail in comfort and know that I can get my wife and kids back to the camper at the end of the day.” Continue reading

  • How to Fill Your Dynatrac ProRock® Axle with Gear Oil

    A couple of questions we are frequently asked by customers is how to properly fill their Dynatrac ProRock® axle with gear oil, and which gear oil is best to use. Let’s dive right in!

    First, we recommend a high-quality GL-5 mineral-based gear oil (not synthetic). In moderate to cold climates, use SAE 85/90. If you live in a hot climate, use SAE 85/140.

    The specific fill procedure is a little different for the Dynatrac ProRock 44™ and the Dynatrac ProRock 60/XD60® axles. We go through each in the following sections. Continue reading

  • Why Ring Gear Load Bolts are Useless

    We've had several people ask if load bolts are a useful method of strengthening ring gear teeth. The answer is that load bolts are NOT helpful for off road vehicles. Furthermore they mislead users into thinking they’re protected if their housing is so equipped. This is why Dynatrac’s focus has always been on designing a highly rigid housing as the best way to ensure gear strength and durability. Spend your money on a US-made ProRock, and not a load bolt gimmick. Continue reading
