Questions and Answers

Ask a Question


Casey on -- Asked: Would this work without machining for a 11.5 14 bolt ff in a 2008 Chevy Silverado 2500hd

Answered: No that is an AAM axle not a Corporate 14
Pfunk on -- Asked: What is the i.d. of these I am looking to do do a 14 bolt 40 spline conversion and the axles measure 1.715 o.d. Thank You.

Answered: These have an ID of about 1.60" so you would have to open them up more. But the OD of the spindle is only 1 15/16" at the thinnest point(threads of the spindle nut, Outer bearing OD is about 2") so you would have a pretty thin wall at this point.
Scott on -- Asked: So which of you're 14b brake kits do I use for this spindle? Thank you

Answered: So if you want a bolt on application you would need the 14 bolt flanges as well and weld them for the correct spacing. With the bracket on, it needs to rest about 9/16" from the inside brake surface of the rotor so you have enough room for the caliper and pads. If you need a weld on bracket, we can get you set up with a kit and substitute them into one of the brake kits over the phone.
Lakota on -- Asked: Could I put the stock hub and emergency brake on this spindle with out problems ?

Answered: To the best of my knowledge these will work with stock components on all 14 bolts that came with factory drums. Disc brake 14's had different spindles
Scott on -- Asked: My question is can you tell me the distance from the weld surface to fully assembled WMS . I need to decide if I have enough axle tube to make this work.

Answered: It measures 5 1/8" with a 14b SRW hub
