Double shear captures the tie rod or steering ram from top and bottom, using factory tie rod location ears and our arms.
-Stock 4 stud GM knuckle pattern
-Reid Racing Knuckles 5 stud pattern (Highly Recommended)
-Some Dodge Knuckles (those that are similiar to GM-tie rod locations seem to vary, bolt length may be too long)
Fit factory Ford Knuckles, the 3/4 Bolt won't line up. (Upgrade to a Reid knuckle-Ried uses a Chevy knuckle with Ford spindle pattern)
Spring-less king pin pre load design. Giant 7/8" chrome moly pre load adjuster bolt and T1 king pin bushing wear plate included. Load bolt is manufactured by Sky's for this application, not a 3/4" set screw from from the local hardware store!
Comfortably the arm will clear a 4.500 back space 17" wheel. We have run these on tighter backspace with minor sanding of the arm, the biggest issue being deflection of the wheel in extreme use ( King of the Hammers) and actually hitting/flexing the wheel into the arm. This has cause catastrophic failures of the wheel.
Arms use tapered nuts to add resistance to side shear.
Designed around an 8 inch stroke ram. Arms do require sizing lower tie rod hole to desired size of rod end. Arms come with 3/4 pilot based on Dana Spicer location.
To determine you have knuckles that will work, you can use a framing square, "L" square. Lay square across spindle face of the knuckle and over center of tie rod bore. This number should be 2.250" or dangerously close.
Uses factory length studs or our upgraded studs.
Want to run double shear and not full hydraulic steering? We now offer a variation in our passenger side steering arm with a 5/8ths drag-link pilot hole to run either a tapered TRE or a standard bolt. THIS MAY REQUIRE FURTHER DRILLING/REAMING
Steering Arm Info:
Our steering arms are CNC machined out of ASTM A572 Grade 50 steel. We previously have used 1018 steel, but switched to a more rigid material (A572). Grade 50 is a very strong low allow steel that fulfills our exceptionally high strength requirements, and is particularly strong for applications in which it is riveted or bolted. ASTM A572 Grade 50 is considered a "workhorse" grade and is widely used in many applications. Steel mills produce channel and heavy beams with Grade 50. It is commonly used in structural applications, heavy construction equipment, building structures, heavy duty anchoring systems, boom sections, structural steel shapes, and applications that require high strength per weight ratio.
