What size tires do you run with your Longfields??

[pumkin toy]

I'm wondering what tires most of you guys are running with Longs, and how often you break them.  I have a birf elim kit in the front of my rig with the superjoints. I have already broken three of them and i'm running 37's with beadlocks at 5psi.  The axles have a lifetime warranty but i am getting sick of breaking them!  i thought they would hold up to 37's better than that.  So now i am considering Longs and wondering how much stronger they are.

I have been running them a couple years now on 39 inch bfg red label crawlers and about 5 psi with no breaks at all and i have used it plenty hard they are worth the cost

damn!  so according to bobby long his axles are almost twice as strong as my birf elim kit!   i really wish i knew more about the longs a few years back when i bought the elim kit.

[Slolyfe]

Im running 37" mtrs at 7 psi and marlins chromoly inner and outers never broken one

[87pickup]

37" maxxis creepy crawlers @ 4psi. I have redlined the 3rz in double low and never broken a thing.

I have been running them a couple years now on 39 inch bfg red label crawlers and about 5 psi with no breaks at all and i have used it plenty hard they are worth the cost

Thats a true testament if they are standing up to red label 39's 

[topar]

Longs Hub gears, birfs and 30 splines. with a v8 and 5.29 gears and 36" Iroks.  No problems other than the broken transfer case which has kept me from wheeling for about 2 years now   However you wont go wrong with Longs!

[88_Pathy]

Marlin Chromos with 37 MTRs. Work great.

[Volcom]

39.5" Iroks, standard black steel wheels, (4-5 psi on the trail) with Longfield 30 splines & Hub Gears.  Never had an issue and I don't carry any spare front axles with me.

[pumkin toy]

well its sounding to me like i REALLY need to invest in a set of longfields!  i am tired of breaking axles.  Thanks for all the info guys!!

I believe he asked for LONGFIELD.............not Marfield

[freds40]

Ben is running them in his XRRA buggy. IIRC the tires are 42" Pitbulls.

damn!  i need some Longs!

[Thomas P]

i was runnin 39.5" Iroks for 2 years and now 42" Iroks for the last year and a half, and no problem with my longs

[boggerunner]

37 mtr's with 5 psi for 3 yrs now

[95SAS]

38.5s 7 psi for a week or so....
37s 5 psi for about 6 months

And I beat the crap out of them too, No problems yet.

[Thomas P]

i forgot to mention i run 3-7 lbs in my 42"s depending on situation

[pumkin toy]

yeah i think bobby has his axles figured out!  i really need some.  maybe i can sell my house soon and buy some

[Nothingface5384]

i'll be only running 35x12.50s..perhaps 37s down the line
i got the new style that turns an extra 40 degress

[RokCrawlinToy]

Irok 42s@ 4-8 psi depending on terrain, 30 splines drive flanges

[pumkin toy]

so i was lookin on there website and it looks like its about an 800 dollar bill for inners, outers and hub gears.   i'm gonna have to start saving

[Nothingface5384]

no.. i only paid like 695 for 30 spline superset plus pair of hub gears..

[DieselD]

Ive broke a inner side short side long...running 38x12.5 SXs

buy them, they are pretty much as good as it gets unless your going 1tons and then even they have there own issues

[pumkin toy]

no.. i only paid like 695 for 30 spline superset plus pair of hub gears..

well looking at their website it shows the superset is 630.00 and the hub gears are 65.00 each so that comes to a total of 760.00, plus shipping it would be almost 800 bucks.  but i still think it is worth it.  i'm so over my birf elim kit. its a PITA!  the axles are a pregnant dog to put together with the big u-joints, and i had to clearance my housing, and i had to replace my stock spindles.  so now if i want to get Longs i have to buy a pair of stock spindles because i sold my old ones!

buy them, they are pretty much as good as it gets unless your going 1tons and then even they have there own issues

yeah i could get a set of 1 tons from my boss for pretty cheap but its alot of work to install them.  plus my toy axles already have gears and lockers so it would cost alot more to get tons.  that would be my last resort.  i'm gonna get some Longs as soon as i can afford it.

[87pickup]

I think longfield has free shipping. I just bought some drive flanges and they were shipped free

[Nothingface5384]

yes, they do

[Halladay]

i have a buddy that is selling birf eliminators for 300 is that worth it i have a open front diff but when and if i get that kit im gonig to spool the front. and i have 35's now but going to 37" mtr's

well it might be worth it just for the fact that you can get new axles for free from the lifetime warranty.  and they will be stronger than stock birfs for sure but you will probly still break them.

[pumkin toy]

here is some pics of the one that i just broke.  this break was less catasrophic than past breakage i have had.  the last one i ended up breaking both the inner and outer shaft into about four pieces each.  i have never broken a u-joint though.  i think the weak area is the narrow edges that wrap around the u-joint.  thats what broke this time. the other thing that sucks is when they do break, the snap rings and bearing caps get all chewed up and get stuck inside the knuckle when you turn it.  the inside of my knuckle is all beat to hell from those axles.
