Description
The Custom Length Heim Joint Steering System is meticulously crafted to deliver exceptional performance and reliability for off-road enthusiasts and street drivers alike. This system features 1.25-inch DOM tubing with a wall thickness of 0.2815 inches, ensuring maximum strength and longevity.
Key benefits of the system include:
– Threaded tube design eliminates the need for weld-in inserts, enhancing strength and ground clearance.
– Drag link mounts to the tie rod in the optimal location using a welded “saddle,” maintaining factory geometry and preventing bump steer.
– Advanced design significantly reduces torque and stress on the passenger side steering knuckle.
– High-strength, Teflon-lined, 3/4-inch rod ends paired with Grade 8 bolts facilitate full articulation without binding.
– Requires modification of existing stock knuckles to 3/4-inch unless paired with the available heim stud kit.
– Pitman arm features a specialized tapered heim stud, requiring no drilling for installation; compatible drop and OE replacement pitman arms available.
– Installable under or over the knuckle, suitable for DIY setups in garages or driveways.
– Optional accessories, including a bump steer eliminator and weld-on c-cap mount kit, enhance performance for specific applications.

I purchased this kit for my 75 along with heavy duty trac bar with heim, trac bar drop bracket and trac bar riser. The quality and strength is fantastic. I have a 5.5” suspension lift and the geometry of the steering system is as close to perfection as possible with this kit. Haven’t driven it yet as I’m still in the restoration process but I’m sure it will have eliminated my previously terrible bump steer.
Can’t wait to get it back on the trails!

update to my previous review after install: Now that I have a few hours behind the wheel i can say that this set up is awesome. Before restoring I had terrible bumpsteer that would literally send you into the other lane of traffic at times. 100% of that has been eliminated with this kit. I hit bumps both big and small and stay straight as an arrow going down the road. I have so much more confidence and peace of mind while driving this thing now!
