Very good quality product! Was a huge upgrade from my stock 3.55 ratio to 4.56 with 37” tires. Freed up so much power! Had them professionally installed and took about 4 hours.

Raptor SVT with 39 K2Os
I used this to get closer to the stock torque after installing 39-in BFG tires. On my 2014 Raptor SVT I pull a 12-ft 8000 lb trailer 90% of the time. And was looking for a way to get some better get up and go power
