Also, do those air bags help with sway back and forth, in addition to supporting it when towing? @M3kanic
I think it was one of the best up grades I have done in regards of towing. Yes they helped. For under $100 and about 2 hours worth of work. They are a pia to put in.

My parking brakes have never worked since I bought my truck but I might try to see if I can rebuild them. I've heard they leave a lot to be desired as they say.

I personally haven't hit mine since I bought it for fear that it never got used before and won't let go if i do. Plan to rebuild it with the rest of the brake system. Then I'll keep it exercised.

What kind of intake? He's supposed to be getting one also, which he might sell.
U will need an intake to match the square ports.. the ports on our heads are cathedral shaped. The truck intakes and cathedral porting is good for torque which is what u want in a truck. I haven't looked into the gains using ls3 heads, but I've head square port heads like L92s are sluggish down low but would make more peak power. Depends on your goals.

Next thing I bolt to my engine will be a blower using my 317 heads lol.

As I promised yesterday in my post, here is the mod of the day!

20170831_004624.jpg


Can you tell what it is?
No?

I did the 4-HiI mod for the headlights on both our trucks!

20170830_175953.jpg

I put the HIDs back in my low beams (only the HIDs and the HIR 9011 bulbs seem to be bright enough/good enough pattern to use in these projectors), and put the LEDs in the high beams.

Both our trucks have an aftermarket headlight relay kit installed, so it can run the 4-HI mod with out taxing the stock wiring.
Because both trucks have the aftermarket relay kit, it was VERY easy to do the 4-Hi mod.
On my truck, I only had to jumper from ground to the low beam trigger/input ground wire.
On my dads truck, I needed a diode and I ran a wire with diode in to from the high beam trigger +12 wire to the low beam trigger +12 wire (cathode of the diode pointing to the low beam wire). If we hadn't had the relay kits, we would have had to use a relay instead of a diode to run the low beams on his truck.

After I took the top picture, I turned on the light bars on both trucks (and LED fogs for mine) and took a picture:

Take a look across the cul-de-sac:

If we go by what the claimed on the box, that's about 14,000 lumen total from both trucks.
