Suspension knuckles, steering knuckles, wheel carriers, bearing housings, uprights…these components go by several names, but they share an important job. Located behind the wheel hub, they serve as a mount for the wheel bearing and the link between the wheels and the vehicle’s suspension. On the front of the vehicle, knuckles can be attached to the axle end, control arms, or strut, and they’re also where the steering system connects via a tie rod to pivot the wheels left or right. At the rear, they have a hub and bearing through which the axle or half shaft passes.

Suspension knuckles, steering knuckles, wheel carriers, bearing housings, uprights…these components go by several names, but they share an important job. Located behind the wheel hub, they serve as a mount for the wheel bearing and the link between the wheels and the vehicle’s suspension. On the front of the vehicle, knuckles can be attached to the axle end, control arms, or strut, and they’re also where the steering system connects via a tie rod to pivot the wheels left or right. At the rear, they have a hub and bearing through which the axle or half shaft passes.
Suspension knuckles are stout parts, designed to last the life of the vehicle, but the various bearings and bushings attached to them can wear out over time. For trail rigs and rock-crawlers, consider upgrading your knuckles to withstand the extreme impacts and abuse of off-road action.
No matter what kind of knuckle you need, Summit Racing Equipment has it! For stock replacements, we carry trusted brands like Dorman, Crown Automotive, and ACDelco. For off-roaders, we carry Rancho, Superlift, OMIX-ADA, Trail Gear, Quadboss, and many more.

After years of development and testing, Trail-Gear fully loaded Six Shooter kits have set a new standard for Toyota knuckle strength and reliability. They totally eliminate the problem of broken steering knuckles and studs. The addition of two studs in each arm effectively prevents the steering arm from becoming loose or shearing off the studs under extreme loads. The knuckle housing was designed with thicker-than-stock material, and larger gussets have been added around the outside of the knuckle for extra strength. Precision CNC-machined, each set of knuckles and steering arms are inspected and tested for the highest quality of products that Trail-Gear can deliver. These kits include a special 6-hole shim pack for use between the top of the knuckle and the steering arm assembly. A minimum of four additional steering arm studs are required for installation.

Spidertrax Off-Road Ultimate steering knuckles set the standard for rock crawling and rock racing performance. They now include 7/8 in. spherical bearings and 4340 Spider shoulder bolts across the line. In addition, they feature internal gussets on both upper outer knuckle and lower inner knuckle, adding crucial strength from extreme steering forces and those high impacts from jumps. Ultimate knuckles are designed for Ultimate unit bearings, Ultimate U-joints, and 4140 bolt-on high steer arms (sold separately). They install on any Spider 9 housing with 3 1/2 in. O.D. tubes. * CNC-machined: Tight tolerances are necessary for proper fitment. Post welding, all inner knuckles are CNC-machined. This provides not only a perfect 7/8 in. spherical bearing fit but a precise tolerance between upper and lower spherical bearings. No guesswork, no compromise. * 7/8 in. bolts and bearings: The spherical bearing assembly consists of a 4340 Spider shoulder bolt, shim washer, spherical bearing, shoulder washer, and Type C nut. Combined, each knuckle can withstand over 21,500 lbs. of axial loading and over 130,000 lbs. of radial loading. No grease, no weak links, no hassle. * 50 degrees of steering: An OEM-style 60 knuckle can turn only 38 degrees. Ultimate knuckles can turn all the way to 50 degrees, tighter than any steering knuckle on the market. Plus, the use of a 6-bolt interlocking chromoly steering arm makes them one of the strongest, as well (steering arms sold separately). * Internal gussets: Ultimate knuckles take performance to an all-new level with the addition of internal gussets. Upper outer knuckle gussets add critical strength for steering, while lower inner knuckle gussets add extra strength for those high sailing jumps. They're simply Spidertrax's strongest Ultimate knuckle yet.
