4.88 gear questions.

My rear blew out last night.... it's stock so it has the 4.10... it has 33's and is very sluggish i was told if i put 4.88's that'll give me more power now all i have to do is put the new gears or i need a new rear entirely? also if i just need the gears can you link me to a site to purchase them?

gears are extremely technical to install. but if you are up for it it can be done, with much research. Randy's Ring and Pinion is a pretty respectable gear specialist. Randy's Ring & Pinion. The Differential Experts. Auto Parts & Services.

If it is just the gears that failed, you can replace them, as stated it is highly technical, I would not try it. But I would not spend a nickel on that D-35 anyhow, sounds like a good time to upgrade to a Ford 8.8.
Just my $.02

I'm with these guys. You might want to go with something more stout than a D35. Then again I re-geared my D53 myself and I plan on running 33's but I know what the risk are and I carry spare shafts withe me. As far as new gears go, you'll need the master install kit that comes with new bearings, seals, etc. I also suggest replacing the outer bearings on the rear axle. Of course if you do one axle you need to do the other. (You don't absolutely have to but you can't use 4wd if you don't).

I have Yukon gears in mine and you can get a master install kit from any 4wd store and online.
