Alright i'm going to get my truck tonight and have a few questions. It will be sprotin' a 6" lift. Should I get a Skyjacker "system" w/ rear springs or just get the blocks? I will beat on this pretty hard and want something that will stand up to it. Has anyone have the Pro Comp Xterrain's on right now? I saw this tire and it looks like a decent tire just want some opinions. What is the general consensus here, lock the front or back axle, or ***** to the wall lock them both? 1 more :-) What gears should I run with a 6" lift and 35" tires. Thanx guys! I'm so excited about getting my truck!

I'd suggest the system. The high blocks will make more wheel hop (leverage). Don't know about procomps, but I like my BFG muds they are a great tire, lots of people think so i got a lot of opinions when i bought mine. We need to know what kind of driving you're going to be doing, off road/on road time and what you're going to be driving on before i can suggest what type of way to go wthi the diffs. 4.10 gears will do well for the 35s, it's a good mix between gas and power. Also, if you're going to be doing any towing, or need some more serious acceleration with the expense of gas, 4.56s. 4.56s are a tad aggressive, so my vote is for 4.10s.



Primary rig is Green Thunder:
95' F-150 XLT 4x4, 302, 5 spd, MSD 6A, Flowmaster American Thunder Exhaust, Sunroof, Clear corners w/ Diamond headlights, CD player with 2 10" subs and some 32" BFG Muds .

Then theres:
99' Mustang GT 4.6L
88' F-250 Heavyduty 4x4 351/c6
95' Mercury Cougar 4.6L V-8
80' E-350 300/6 with a
3 spd column shifter. Weighs around 7,000lbs w. 65mph top speed, who wants to race me!

 

It will be offroader everyother weekend, trails and sand and if i can find some mud. It will also be my daily driver. I'm not too worried about the locker in the rear though. I am undecided on the front, I have been hearing conflicting info on good or bad. Anyone care to help?

 

If your daily drive doesn't involve extended intersate travel over 65mph I would go with the 4.56 gears. That is what I have with 35" tires on my '78 F150. At high speeds they don't do any favors on gas milage but the acceleration is much better and you will be vey happy with them out on the trail. Driving a big rig sometimes takes some finess and the lower gearing helps alot.

 

Yeah, the 4.56s would be real tough on the highway. I again, suggest the mud terrains. They are a great all around tire. Sand, mud, snow, rocks, dirt, street, anything they do well with.

I will have to back MustangGT221 on the BFG mud terrains (35s). I am on my 3rd set of them and the first 2 sets got 60k and 63k miles. I am hoping the 3rd set does as good as the first 2. On the flip side, a friend had a set of BFG all terrains that did not get nearly as many miles out of them and they were 33s. ??Go figure?? Could be difference in trucks, driving style, tire, who knows. The key is keeping them rotated and keeping them lined up. I have had good luck in mud and snow with them but would be leary of the sand.

I would also suggest the 4.10 rear. I have a 3.55 rear and it is a little high. I run in drive rather than OD most of the time unless I am on the highway going over 55 mph. I do pull a 18' boat with no problem but that added low end would be nice. I think that 4.10 would be perfect for my truck but it all depends on what you are looking for out of your truck. Just my opinion!

Good luck with the truck.

 

Many many factors contribute to tire wear. Alignment, weight, driving style, how hard you are on them, highway or city driving, tire pressures, just about anything. I harldy drive on the highway, i'm constantly turning because I life in a small town, so i'll be lucky if I see 40k out of them.

I have 33" procomps, put 6,000 miles on them and they have worn evenly only taking off 1/32 of an inch in that time, Didnt even have to be rotated yet.

 

what kinda of truck are you getting?????
if its got over drive, go with 4:56's
if it dont go with 4.10's unless you rarely drive on the highway then go with 4.56's too

i also recomend the bfg muds, a time tested design, long lasting, best "mud terrain" tire, and you cant beat 3 ply sidewalls

 

It is an '87 F250. I think I will hold off on the gears for awhile because I have 4.10s in there now. If I get the new gears I won't be able to get a winch. What brands of lifts and winches do you guys recommend? I'm thinking a 6" skyjacker lift and a warn XD9000i winch. Thoughts? Oh yea, anyone have the procomp xterrains? Those look like a sweet tire! THanx guys.

 

The BFGs have a nice aggressive look. I'd suggest skyjacker they are the best. I wouldn't suggest 4.56s, even with OD they can run pretty high RPMS. With 4.56s and 35" tires, you'll run 2800rpm at 65 in 4th if you have a manual, and 3rd if you have a automatic (1:1 ratio). If you have an automatic, they slip a little, so figure 3k, AT 65 MPH.

With 4.10s, you'll run a much better 2573rpm at 65 in the 1:1 gear ratio.

Here's my math:

(MPH X Gears X 336) / 34.8 (overall tire diameter).

* 35" BFG muds are really 34.8"

(65 X 4.56 X 336) / 34.8 = 2861rpm at 65mph
(65 X 4.10 x 336) / 34.8 = 2573rpm at 65mph

Both are taken with the tranny in a 1:1 ratio. Tell me what tranny you have, I will look in my book as to what the OD ratio is, and be able to tell you what RPMs you'll run in OD. But keep in mind an auto slips a few rpm.

65 x 3.55 x 336 / 30 = 2584 RPM

65 x 4.10 x 336 / 30 = 2984 RPM

*Food for thought .

I have a 4speed manual. Right now I have 4.10s in the truck and I am turning like 3100 to 3200 at 65.. So you are saying if I go to a larger tire it will lower the rpm? They are just stock tire sizes now. Yea I was thinking the Skyjacker lift. Would it really make that much of a difference if I went with a 35x14.50 than a 35x12.50? Also what would you guys recommend for lockers/ls? I want the back locked. Who makes a limited slip for the D50? Thanx!

 

[updated:LAST EDITED ON 30-Aug-02 AT 02:18 AM (EST)]definitely go with skyjacker, they make a good quality kit, and go with a detroit locker in the rear if you are going to be driving on the street alot, you wont be able to feel it onroad...unless you do alot of driving on ice. anyway the detroit is great offroad, and indestructable. I would not reccomend wasting your time and money on putting a ls in the front, ill bet the rear locker will make you happy, unless you are planning on rockcrawling or something of that nature

is this a daily driver? if it is i would suggest a good radial like the super swamper ssr, or the bfg mud terrain, i have little experiance with the x-terrain, i just have a buddy who has them on a yota, they seem to be ok, he never goes off the pavement with them

mustang...
to find the od rpms, you multiply the rear end gear(lets says 4.56) by the od reduction, lets say around .68 (about avg for ford auto's), so if he did have od at 65 with 35's he would be turning (apprx) 1,934 rpms [plus slippage unless he had a lockup convertor like all new trannys] thats about where i like it, but since he has no od, and already has 4.10's, he is set to go, 35's will be no problem and it will feel about like a 3.40 gear with stock tires..a good comprimise for highway cruising and off road/towing capability

so to answer your question 1248, dont worry about gears, 4.10's will be perfect with 35's, and lower your rpms to (apprx) 2,558 rpms @65 mph

sorry for my rambling i could go on about gears and suspensions for hours, ill bet nothing i said makes any sense

hope i helped some?!!

 

Here's my thoughts:
As far as the suspension goes I'd get the Skyjacker. I've heard alot of good things about them and what little experiance I have w/ them was good as well. Also, If you have the money getting new rear springs is the best way to go.

As far as the lockers- Locking the rear will add a tremendous amount of traction. Unless you do some really serious off roading a front locker isn't really needed. I had a spooled 9" in my last setup and I loved it. That thing would climb like a mountain goat, even in 2wd. My current setup has a Trac-Lock and I hate it. After driving on a spool for over a year that posi seems pretty lame. Problem is I don't have the money to spool a Dana60. Oh yeah, an 87 F-250 doesn't have a Dana50 frnt. I believe they had a D44 TTB setup. They might have made a HD version w/ a strait axle but I'm not real sure on that one.

I've heard very little about the X-terrain. What I have heard is that they work well on most any terrain (especially rocks) but I suspect they will clog up pretty easy in serious mud. They do look cool though.

One last thing- W/ 4.10's and 35's you'll be just fine. I have 4.10's and 36's right now and I believe it's a very good combo.

 

he should have the dana 50 ttb, the hd f-250's came with a full float rear and the dana 50 ttb front up till the superduties, starting in 84?? the f-350 got the monobeam dana 60
