Helpful thank you. Agreed the instructions leave a lot to be desired and I wish the level of detail and thought was aligned with the quality of work I see from their shop.

Re: Amp Research Powerstep

I agree the work is nice. The brackets seem to be either laser or water jet cut. They are nice and I haven’t had fitment issue on the truck. I’m hoping I have the right brackets but FedEx is running late so I may not know until tomorrow which motors I have. Any chance you can grab a picture of where you had to trim the rocker box?

Re: Amp Research Powerstep

I dont have a pic of the clearance I ground into the rocker box but you can see the interference here:

Name:  RockerClearance.jpg

the outer edge of the top of the step comes in contact with that lip. you can see the bolt head/washer to the right of that lip. I ground probably a 1/4"+ semi-circle to clearance that once spot on both sides. It still hits a little bit but i'm fine with it.

When you test fit the steps and cycle them manually you'll be able to tell where to trim.

Quick shot of the motors I received. I haven’t checked for fitment yet.

Not the motors - you need to check the motor housings. They will already be attached to the rear AMP arms.

Re: Amp Research Powerstep

Appear to be plastic. I emailed Nick and he said I have the new version of the brackets so should be no issue.

Nice - glad I could be your guinea pig
Good luck with the install!

Re: Amp Research Powerstep

I have mine installed. I had to grind the boxes as well. Very light amount on the drivers side to clear and I installed some button head bolts. The passenger side took a little more material to clear. The bolt required a little grinding as well. I used a small belt sander to remove the material and have control. I mounted the control box near the battery in the engine bay. Its small and and had a spot right behind the radiator overflow. Then I just ran the wires down the frame and connected them. I had to extend for the driver side. One thing to note the wiring is grounded together for the interior lights. I had to cut the ground from the right side to stop both steps from coming down with one door open.

That's what the diodes are for that HB provides. But I guess you found another way to do it?

Re: Amp Research Powerstep

No I used the diodes and still had the issue. I was wondering why that didn’t work. I just eliminated the bridged ground and I think that solved the problem. Edit - I see I installed them wrong now. Oh well not a big deal. I might fix them later.

Re: Amp Research Powerstep

Fixed the wiring. Now it works as it should.
I trimmed my inner fenders. Used an air body saw. Came out pretty good. I just need some touch up paint and see if they clear.

Looks good. I dont have access to an air saw so i'll have to finesse it with my grinder/cut off wheel and maybe use a drill bit to radius the corners.

Re: Amp Research Powerstep

Highly recommend the air saw if you can buy one but the cut off wheel and grinder will work. Its hidden so it doesn’t have to be pretty.
