Arms are pre-tapered for FJ80 tie-rod ends and can be reamed for GM 1-ton TREs or heim steering; each arm is double-tapered for left- or right-hand drive. Stud layout increases spacing to reduce leverage on the arms, and the lower cap is counterbored to protect hardware for reliable clamping under load.\u003c\/p\u003e\n\u003cp\u003eThe assembly uses 25mm trunnion pins and bearings for higher load capacity, with outer four Dana 60 studs (Grade 10.9) and two inner 1\/2\" Allen bolts (Grade 14) securing each arm. On stock FJ80 suspension, track bar relocation is required to clear the tie rod and correct drag link angle in a high-steer position. ABS sensors and brake backing plates are not retained due to knuckle thickness, and wheel backspacing must not exceed 4.5\".\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003ePart Number: PN2149\u003c\/li\u003e\n\u003cli\u003eFits 1991–1997 FJ80 front axles\u003c\/li\u003e\n\u003cli\u003eTrue high-steer arms with 6-bolt retention; increased stud spacing\u003c\/li\u003e\n\u003cli\u003eShimless set-screw knuckle preload (no shims)\u003c\/li\u003e\n\u003cli\u003eArms pre-tapered for FJ80 TREs; reamable for GM 1-ton TREs or heims\u003c\/li\u003e\n\u003cli\u003eOuter four Dana 60 studs (Grade 10.9) + inner two 1\/2\" Allen bolts (Grade 14)\u003c\/li\u003e\n\u003cli\u003e25mm upper\/lower trunnion pins and bearings for increased strength\u003c\/li\u003e\n\u003cli\u003eCounterbored lower cap to shield bolt heads\u003c\/li\u003e\n\u003cli\u003eMaximum wheel backspacing: 4.5\"\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eKit Includes\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e(1) Pair FJ80 Hellfire high-steer knuckles\u003c\/li\u003e\n\u003cli\u003e(1) Pair high-steer arms with FJ80 pre-tapered tie rod and drag link holes (double-tapered for LHD\/RHD)\u003c\/li\u003e\n\u003cli\u003e(2) Sets 25mm upper and lower trunnion bearings and pins\u003c\/li\u003e\n\u003cli\u003e(1) Pair lower 25mm caps (pin welded in place)\u003c\/li\u003e\n\u003cli\u003e(8) 1\/2\" Dana 60 chromoly studs and nuts\u003c\/li\u003e\n\u003cli\u003e(4) 1-1\/4\" × 1\/2\" Allen head bolts for arms\u003c\/li\u003e\n\u003cli\u003e(8) 1\" × 1\/2\" Allen head bolts for lower caps\u003c\/li\u003e\n\u003cli\u003e(2) Set screws with jam nuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eNote\u003c\/h4\u003e\n\u003cp\u003eFor off-road use only.
