Marlin Crawler has revolutionized the Toyota 4WD industry again, this time with the strongest 1979-85 Toyota steering pivot system in the world.

Our new Competition Series Steering Upgrade Kit replaces the stock wimpy 17mm pivots with beefy 25mm Chromoly pins. These days with larger tires and hydro-assist steering systems, we often come across Toyota axles with blown up knuckle bearings or even worse, sheared knuckle pivot pins. The Marlin Crawler solution to this weakness starts with pivot pins that are 47% larger than stock and *updated* High-Capacity knuckle bearings that are 54% stronger with an increased contact area. These puppies are nearly the same size as Dana 60 parts!!

Next we replace the stock flimsy lower caps with an incredibly stout solid billet version.

Then we finish it off by replacing the long and exposed stud design with grade 12.9 cap bolts and serrated conical washers made in Germany. The end results is an increase in ground clearance by as much as 3/4", measuring only 1" thick!

• 25mm Chromoly knuckle pivot pins (47% larger than stock), made in America
• 54% stronger KOYO High-Capacity knuckle bearings made in Japan
• Billet lower cap using grade 12.9 studs increases ground clearance up to 3/4"

Would you put your stock Toyota parts to this kind of abuse? Here our Tundra V8-powered test rig bashes its 42-inch Pitbull ROCKER tires into the ground, defiled by Marlin Crawler Competition Series parts!

Kit includes everything needed to fully convert a 1979-85 Toyota front live axle to a competition series Marlin Crawler axle including our Billet HySteer arms, all parts made and heat treated in America excluding Japanese bearings and German fasteners. Fully compatible with stock knuckles and axle housing, no modifications required.

If you already own a pair of Genuine Marlin Crawler Billet High Steer arms, then the pins are already compatiable, and this full kit is not required. You may want to consider our Upgrade Kit instead.

The Marlin Crawler Heavy Duty 25mm Chromoly Pin Upgrade

(click on images for a larger picture)

	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 defines the 47% size increase of the 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.
	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!
	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.
	All Billet Steel parts along with their 25mm Chromoly pins are all made in USA. As you can see on the lower caps, we are quite proud of USA made parts!
	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!
