Sky's Off Road Design Dana 60 upper king pin cap.
Designed to add style and strength, as well as match our steering arms but in a blank replacement cap.
Replaces stock ugly steering arms, or stamped light duty factory style caps. Tapered seats help align arm to knuckle.
CNC Machined from A572 steel, includes 7/8ths king pin pre load bolt and pre load washer.
Sky's chromoly Dana 60IK studs fit these caps.
Setting kingpin preload:
Jack up the bottom of the knuckle until its snug, but not lifting the axle, pull the cap, spring, plastic bushing, install the bronze (or leave the plastic one in if you don't have bronze) clean the mating surface of the knuckle up and install studs, set the preload washer on top of the bushing, install the arm on the studs. Thread the set screw into the arm until it seats on the Preload Washer. Now torque it to 15-20 ft-lbs. Drop the jack, adjust it from there.
**Note** 20 ft-lbs was the torque we needed to preload the kingpin to equal that supplied by the stock
spring. Use this number as a starting point. With the steering links disconnected from the knuckle, turn
it from lock to lock with your hands. If the knuckle has any vertical play, torque the set screw more. If
the knuckle is too stiff (use the other side to compare), back the setscrew off in 1/4 turn increments until
you get a desired kingpin preload.
Now Secure the Set Screw in place using the large nut.
