High Steer Kit for Hilux

Marlin Crawler High Steer KitHigh Steer Arms

Crossover steering systems replace the factory push-pull system eliminating about 90% of bump-steer. With High Steer crossover steering, the tie rod is moved up and above the leaf springs. This places the rod out of the way of most trail obstacles and provides a clean factory look. Our kits feature our USA-steel and CNC-made Solid Billet Steel steering arms, and are packaged with our Heavy Duty 1.25" X .250 wall USA-steel and U SA-made D.O.M. seamless tubing and oversized FJ80 tie rod ends. The kit also includes a one piece pitman arm to complete the conversion. IFS-type Steering box and mount kit are required on '79-'85 Pickups/4Runners, sold separately.

Fits 1979-85 Pickups and 4Runners, and 1986-94 solid axle swapped Pickups and 1986-95 solid axle swapped 4Runners. Please be aware that at least a 4" suspension lift will be required to fit the High Steer system.

High Steer Steering kit features:

  • Superior Quality USA Billet CNC Machined Arms
  • Strong USA-made 17mm Chromoly Pins
    • We use a 78% larger 1-inch diameter pin-to-arm connection
    • The largest and strongest pin-to-arm connection on the market!
  • Heavy Duty 0.250"-wall USA DOM Tie Rod and Drag Link
  • (4) Huge 23mm FJ80 tie rod ends with jam nuts
  • One piece High Steer Pitman Arm
  • Design incorporates our 25 years of installing our HD Steering Kits since 1994

When it comes to the safety of our own rigs, we would never take risks in using lower quality steering components. We sell what we trust and we know you won't be disappointed in our High Steer kit!

We also offer a 25mm Steering Pin Upgrade Kit that includes our 116% larger Dana-60 sized 25mm Chromoly Pins and oversized 54% stronger KOYO knuckle bearings. This is the strongest Toyota Steering Kit in the industry. Please click here for more details: 25mm Steering Pin Upgrade Kit

The Marlin Crawler Heavy Duty 25mm Chromoly Pin Upgrade

Marlin Crawler 25mm Pin Diameter Comparison

When we sought to build Toyota pins as large as Dana 60 lower pins, we never knew the results would be this fantastic.

The image to the left clearly shows the 116% larger cross-section of the High strength USA-made Chromoly 25mm Marlin Crawler Knuckle pin.

By replacing your stock 17mm pins you are increasing the durability and also the safety of your Toyota-axle 4WD vehicle.

Also of interest is that the stock component is a 1-piece cast setup whereas the Marlin Crawler component uses a Chromoly pin that is pressed into a solid billet cap, just like our High Steer arms.

Marlin Crawler Knuckle Bearing 25mm 17mm comparison

Here we have our new updated High-Capacity 8,500 pound-force 25mm KOYO knuckle bearing.

The inner diameter literally dwarfs that of the stock NSK bearing.

Can you believe that our KOYO bearing is 54% stronger than the stock Toyota bearing? You better believe it, baby!

Not only is our pin 47% larger, but our bearing is also 54% stronger to boot! It is a total upgrade package!

Marlin Crawler Heavy Duty Fastners for Knuckle Upgrade Kit

Knowing that no steering linkage is attached to the lower cap, designing stronger fasteners wasn't a high priority of this upgrade kit. But then again this kit is designed by Marlin and he only wants the best parts for your rig! Without compromise, the kit includes high shear and high tensile strength 12.9 grade cap bolts along with high quality serrated conical lock washers made in Germany.

The great thing about this design is that unlike factory studs our bolts do not have shoulders. Therefore our bolts contact 100% of the knuckle's threads providing a high clamping force without fear of damaging knuckle threads. Our lower bolts can be torqued to 65 ft-lbs, which is nearly three times the recommended rating of the stock studs.

Marlin Crawler Heavy Duty Rock Guard Lower Knuckle Cap

All Billet Steel parts along with their 25mm Chromoly pins are all made in the USA. As you can see on the lower caps, we are quite proud of USA made parts!

All of our steering arms and lower caps use a 78% larger 1-inch diameter pin-to-arm connection, which is the largest and strongest pin-to-arm connection on the market.

Marlin Crawler Rock Guard Lower Knuckle Cap Ground Clearance

Another impressive feature of our Billet Rock Guard lower cap is how much ground clearance is gained. As shown to the left, ground clearance is cut by a massive 60%.

Put yourself in a rocks shoe: Would you rather hit an exposed single stud or go face-to-face with our Solid Billet Rock Guard lower cap?

Stop risking bent studs with damaged delicate and exposed threads. Switch over to our Heavy Duty Knuckle Bearing Upgrade today!
