King Pin Bolt for John Deere 6M and 6R Series Tractor Front Axle Steering

Description

When your John Deere starts wandering down the road or you notice that unsettling looseness in the steering wheel, there’s a good chance this critical little bolt has had enough. That clunking noise up front or the way your tractor won’t track straight down the road anymore—nine times out of ten, it’s worn king pins causing the trouble, and when you’ve got sloppy steering and uneven tire wear that’s costing you more than this part, it’s time to fix the problem at its source. This king pin bolt is the foundation of your front axle steering system, keeping your wheels pointed where you want them to go.

What You’re Getting

• Critical pivot point that allows front wheels to turn while enduring tremendous loads and constant movement
• Through-hardened steel construction that won’t just wear off like surface treatments
• Precision machining that maintains critical tolerances to keep steering tight
• Maintains proper front wheel alignment and steering stability under demanding agricultural conditions

Built for Real Farm Work

Whether you’re operating with a loader, doing heavy field work, or running these tractors through their daily paces, this bolt protects vital steering components. The 6M series handles everything from utility work to mid-range farming operations, while the 6R series tractors are built for precision agriculture and heavy-duty field tasks. These pins take tremendous forces from every direction during loaded front-end loader work, tight turns at headlands, and road hauling—they’re what let your wheels turn while supporting the weight of the entire front axle assembly.

Made to Last

Farm equipment doesn’t get babied, and steering components take some of the worst abuse. This pin is built to handle the constant flexing and heavy loads that come with agricultural work, using heat-treated steel that resists wear. The smooth finish prevents premature bushing wear that leads to more expensive problems down the road.

Good to Know

King pin replacement requires proper front axle support and usually means the bushings need attention too—worn pins and worn bushings go hand in hand, so take time to clean the pin bores thoroughly and inspect everything while you’re in there. Set the end play according to specs when you reassemble—too tight binds up the steering, too loose brings back the slop you just fixed.
