I will be installing arh1 7/8 hearder for the first time any tips on how I should do it

 

Driver side from the bottom. Passenger side installs easiest from the top.

Unhook the steering shaft for easier install.

 

Dont what yr make and model but my 08 Sierra in my sig had to remove dipstick and jacked up front high as i could on stands and went in easy with no issues ... ...

 

If it's a 4x4, remove the front driveshaft to make installing the left header easier.

On the right header, you'll need to remove the dipstick tube, then get the header next to the engine, then get the dipstick tube in place, then install the header. If you install the header first, you'll be taking the header back off to get the dipstick back in.

If you run into difficulty along the way, you can send me a pm.

 

i put both sides in from the bottom on my AWD ss, no issues. front shaft stayed in place as well as the steering shaft, passenger side i did remove the dipstick tube but theres no real way around that. The ARH headers fit great, youll love them.

 

Going in to 2009 sierra Denali awd

 

I've never done it in a newer body truck, but mine went in with a little force. As people have said, passenger from the top and driver from the bottom. I definitely had to push it past the steering shaft.

 

If you remove the steering shaft do not spin the steering wheel with the shaft unhooked.

 

Na I will avoid pulling steering shaft is it worth pulling the inner plastic fender

 

I never have.
