37 Inch Tires

[jhndizzle]

can you put 37 inch tires under a 7 inch fabtech lift? cutting i dont mind. what problems will i run into besides the obvisous. oh its a new body style truck.

The extra weight of 37s will put a ton of stress on your front suspension components, which could lead to failure (ball joints, tie rods wheel bearings etc.). The largest tire you can safely run on half ton IFS is a 35"x12.5", and I think that size would look great. You'll have very little room to flex with 37s on only 7" of lift.

how come i see ford 150's with 37's on 8 inch lifts and these guys have no problems. are our trucks weaker than the f150.

Hell No!! I mean what Dan said can be true but it is not very likely especially on a NEW vehicle if you maintain your vehicle well.

The Cognito lift system comes standard with compression struts. Cognito also uses sub-frame connectors to connect the front crossmember to the rear crossmember. Many other companies fail to provide some kind of sub-frame connection. This is essential to prevent bending to the factory lower control arm mounts, and they help provide the Cognito system with a rigid sub-frame to position the lower control arms and compression struts.

With the replacement spindle design, and the upper control arm remaining in the factory location, the control arms are spread further apart by 10 inches. This provides more leverage on the larger wheels thus increasing ball joint life and retaining front-end alignment much better. Lift kits that drop the upper control arm along with everything else are overwhelmed by the added leverage of larger tires, straining upper ball joints and knocking front-end alignments out easily. Some other lift kits do not use a sub-frame, but rather use new upper and lower control arms, longer or stiffer coil springs, and lift spindles. These types of kits are very strenuous on ball joints, because the control arms are not spread further apart to accommodate larger tires as mentioned above.

 

 

 

From what i read there as long as you buy a quality lift you shouldn't be faced with these problems anyways.
