Quality Product- Will Purchase Again In Future

Directions Supplied were not Specific to Product Supplied- Key Stock was Not Supplied for Shock Mounts nor Directions as to Using Key Stock(Length and Installing Them. I feel that the hardware supplied was not of the correct Grade. We Installed with Grade 8 (eight) or Greater Hardware. We always use Anti Size when installing Hardware and Find that when Torqueing to Proper Torque in some instances a Grade 5 or lower grade Even using Anti-Seize , Seizes.

Overall good

Great kit and fast shipping but...... as stated before the instructions are vague and a note somewhere about the keystock would have been nice. Was sent two left side batwings so the whole build got put on hold. I emailed them asking if I was missing something and my reply was you have the wrong parts and need to contact someone else to fix it. I dropped two grand on parts in my order, figured maybe the service could stand up a little more

The only unknown at this time is the ride height. Currently there is no engine or transmission in the car and it's pretty high. I'm not sure if I'll get the height I'm looking for. We'll see. Otherwise it's great.

i am happy with the quality and the price, I would buy again

The Speedway part was unavailable, so the CSR asked if I'd upgrade to this unit. I am so glad she did. This is a really amazing unit.

Page 1 of the instructions say you must use a "Cone Spacer" where the radius rods bolt to the frame brackets. Why are these not included in this kit? And do you sell them? What size?

A couple questions... Is there a limit to the weight of the vehicle like what you see on the tube axles? So it's 48 inch king pin to king pin, what is the overall width once you put on spindles and rotors? Do you ship to Canada? Thanks

Hello, Is this 48" I-Beam Axle Kit have a 4" or 6" drop ? Which Ford Spindles and Ford Disc Brakes do you recommend for this I-Beam Kit ? Any Modern Ford Bolt Pattern will work for me seeing that I do not have wheels yet. Brake Lines ? Panhard Bar Kit ? Steering Box Kit ? .... The original front end has a "cross steer" setup. Can I have Item Numbers also, please ? I want to order everything at once for the front end and combine shipping. Have I missed anything ? Thanks,
