Superlift 6" Install

Just finished installing the Superlift GMT900 6" suspension lift. The total job excluding alignment took 5 days of approximately 6 hours each. The quality of the components is excellent, as are the instructions, and the fitment of the various parts.

This is NOT an easy install, however. There is continual drilling, cutting, tapping, fitting, and unfortunately for me, running after missing hardware.

Although the Superlift kit is excellent, buying if online leaves the buyer at peril. I haven't contacted Superlift yet about all the missing parts, so I can't comment on how they would handle the situation. However if you have the kit and plan to bolt it on yourself, then you might get surprised several times by all the missing parts. I needed to drive out no less than four times just to hunt the various hardware pieces that were missing.

The missing parts included:

2ea 10mm X 140mm allen head bolts

2ea 5/8X 4 1/2" bolts, washers, and nuts

4 ea 10mm stover nuts

2ea 3/8 X 1 1/4" bolts and washers

 

Stock height was 36 7/8" front and 38 7/8" rear

Lifted height is 43 3/4 front and 44 1/4 rear

 

Net lift is 6 7/8" front, 6 3/4" rear

 

Here are before and after pics. Sorry for the poor quality, more to come when the tires get mounted

Secret part... A replacement double cardan driveshaft which makes this lift possible with AWD found on Denalis. I can duplicate this driveshaft if needed...

There is a bunch of stuff that needs to get relocated in the rear to make this lift possible, definately not a two hour job like I once thought!

I like the front end setup. Not a fan of big block lieft for the rear. I'd prefer new springs.

 

What kind of rubber is going on? How about some 38 inch gumbo mudders? WOO HOO!

Nice Job! What wheels and tires do you have planned???

 

Wheels and tires were my biggest single headache. I ordered 4 BFG AT's 18" X 33 trying to get to a 12.50 33. I also ordered KMC Dime127 wheels with the stainless polished wheel lip and black painted spokes. After a week I was told the Dimes were no longer available. So after almost a week of looking at dozens of wheels, I can say I really don't like any of them! I don't like the big wheel 20" chrome scene. Chrome won't get you home is a carry over from my hummer side, so no glitz, thank you very much. Then looking at black wheels, I noted that a black wheel just gets lost at any distance at all.

All I really wanted out of a wheel was more stability, as the lift goes up, the track should go outward a corresponding amount. Well, the axle spacers in this kit put the stock wheels right at the outer edge of the wheel well, so I guess, I got that. So for now, the stock wheels will get the larger tires and we'll see how that all sits...

I agree with you, but when I read that I had to drop the fuel tank to replace the springs, the blocks got the nod. If I get any axle wrap, then I'll get new springs!

      Can ask that about a lot of places.   Holiday sells 91 for $1 over 87 octane. BP 93 is 80 cents. Amoco 93 is 80 cents Kwik Trips is $1.20 for 92 or whatever they have and $1 for the 91.   I know that this is not exactly same as what you are saying with the premium to premium debate of those two stations but why is there such a difference. Top Tier this and that, it's all BS. All the fuel comes from the same damn refinery, so give me a break.

      Why does Mobil Premium cost 90 cents a gallon more than Shell Premium when their regular offerings are but pennies apart?

      Was all the way down to $3.69 a gallon but then jumped back to $3.99 just because for some reason.   Diesel floats between $4.80's to $5.10ish a gallon. I even saw Diesel #1 for $6.09 today but nobody in there right mind even buys that in the summer.

      OTA updates and radio still cuts out

      By Coastie05 · Posted

      Mine just keeps lagging or getting stuck on the reverse camera. When I turn off the truck, get out, and close the door it will still stay on. It’s very intermittent and I would not be able to duplicate the issue.

      Gas Prices

      I was checking out fuel prices at my farm fuel retailer at their pumps and yes the farm price is a bit lower than the non dyed fuel and was glad to see that the regular farm gas price has dropped a lot from what it had been but what blew me away was the price of diesel as the spread now compared to before the prices went up earlier in the year, diesel was actually slightly lower than gas which was a switch from the theme the last number of years. However that sure isn't the theme lately and definitely not right now. The prices I will post are not from that retailer but just looking at gasbuddy for the main city in this area and instead of posting the lowest price someone found I will list the higher price ( and that may not be the highest price, just whatever someone posted on gasbuddy ).   So regular gas and there are a lot of stations listing the same price for regular is 1.68 a liter, premium 2.00 a liter. Diesel 2.03 a liter for a top price I saw on diesel.   Figures out to 6.36 a us gallon Canadian funds for regular and 7.68 for diesel. With the US exchange rate it would be 4.58 us for regular and 5.53 for diesel.    Thought I would figure that out to get a picture of what it settles out like compared to various US prices and its about the same as the current price in Fairbanks AK as Anchorage tends to be lower. So yes, these would be the prices and higher along the way on the Alaska highway where they know they have a captured market !, for fuel prices for those beginning the long drive back to the lower 48   The problem is our Canadian dollar and going to the states that have the high prices, boy do we pay then !
