I HAVE AN 86 K5, I'N GOING TO BE TURNING IT INTO A ROCK CRAWLER. I'M GOING TO RUN THE BILSTEIN 9100 SERIES COILOVERS ON FRONT AND BACK,WITH 39.5 OR 44" CUT BOGGERS. MY DRIVETRAIN WILL BE 1 TON (DANA 60 FRONT,14 BOLT REAR) WITH HOPEFUL THE DOUBLER KIT FOR THE TRANSFERCASE. I JUST NEED YOUR GUYS HELP TO SEE IF I SHOULD EXTEND THE WHEEL BASE, WHAT GEARING, AND IF THAT SET UP SOUNDS GOOD, IF NOT WHAT TO CHANGE AND WHY.... THANKS

I would go with the 5:13's in the axles and at least move the front axle forward. This will help keep the suspension down some. Moving the rear back some to help with the departure angle would help.

I think the biggest thing to watch is the weight. I dropped about 800 pounds on mine on one stage and it was amazing the difference it made.

I ran the 40" Boggers for EJS this year and I wasnt too impressed, even at 3 pounds of air. I ended up selling them and I now run the regular TSL's.

THANKS FOR THE INFO, HOW FAR SHOULD I MOVE THE FRONT AND REAR AXLES.

 

[Sandman]

You can move the front one forward real easy by redrilling the spring perches. I moved mine forword 1.25". It doesnt sound like much but it does add up. Blazinzuk moved his forward 4".

I was thinking of moving my rear axle back some but have not decided on how much yet. The Blazer is already a decent wheelbase so really your just looking to improve the approach and departure angles.

 

[BIG_BLAZER86]

WHEN YOU GUYS MOVED YOUR AXLES DID YOU HAVE TO DO ALOT OF TRIMMING TO THE FENDERS. HOW TALL OF LIFT DO YOU HAVE ON YOUR BLAZER

 

[Sandman]

I cut the hell out of the fenders. I am running a 6" suspension lift with a 3" body and clould clear 44"s with the mods. In fact, I plan on cutting down the body lift.

move the front axle as far foward as possible with the coils. Do not move the rear one back! Bob it. fenders? If it is going to be a rock crawler ditch as much sheet metal as possible :mrgreen: see my ramcharger in the mopar section. :shock:

 

[Sandman]

That is a good point about weight. I lost 800 pounds between Moab trips and could not believe the difference. I'm still cutting off peices. :thumb:

Thank you guy's for the help,please keep them comin'.

You are quite welcome! What you said was either too simple for me.

Shut up ya stupid HO! check your self at the door. Big Blaze you got any pics of your rig. I would add something but these guys have nailed it pretty well. One thing I will add is if your going to run a doubler you could run 4.56 gears in the axles. You will have a decent speed on road and the doubler would make more than enough gearing off road. That is if you drive the rig to the trails or if you trailer it. Just some more food for thought.

Don't have any pictures yet, after christmas I will have a digital camera so I will then. My truck will be one of my daily drivers, but I only work 5 miles away so the gears won't matter to much.

Since i can't get rid of my lift , I thinking of using the 8" springs in the rear. any suggestions how to get them to flex the best. And if so how and were to get the stuff to make it flex. Thanks....

 

[Sandman]

If you are going rockcrawling, 8" might be too high. You can get more flex out of them by removing a few leaves. I've done that with good results.

I'm running 40" tires on 6" of lift and wish I could go down to 4"

I would go with some early 90's Suburban springs. They are supposed to be pretty flexy. And you can keep your inside hangers where they are, and move the outside hangers outward.

Thats my $0.20. Inflation, ya know... 8)
