This is the R1 Concepts Big Brake Kit for the Currie Dana 60 or 70 FRONT Axle.

R1 regards themselves as the American Brembo and we can tell you, their fit and finish is top notch!!!

If you are looking to improve your stopping power (without changing the brake master cylinder), then check out this Performance Big Brake Package for the FRONT of a Jeep JKU with a Rock Jock axle with 5 on 5-1/2 lug pattern (call for other bolt patterns).
