I have 5100 on all 4s with front set at 1.75"(second from top) and the TSB done on rear leaf. I want to set the front 5100 at top setting(2.5"), my ?? is do I need a 1" or 1.5" rear block(to have a slight rake) and will the supplied U bolts be long enough with the extra leaf in back? Thanks for the advice in advance

Do you do any offroading? If YES - I'd avoid the blocks completely.

I've been wheeling for years and I've seen A LOT of people break their blocks while offroading. The blocks break or crack causing the u-bolts to come loose and that leaves your rear axle floating around causing all sorts of other carnage. I've known a guy whom almost got castrated because a piece of a broken block literally flew out and hit him in the inside of his leg while standing behind the truck. You're better off buying a totally new leaf pak for the amount of lift you're looking for.

So they really break that easily? That's scary.
Janster, the castrating one just broke with the truck being parked? Ouch!

But I can imagine that there are different materials available with different strength? If that's the case, what would one need to look for, and where can you get a "good quality" set of blocks?

I may be doing something similar to the OP soon, and would like to know if this setup (with the spring TSB already done) requires new shocks and break line extensions.

Thanks a lot!

I can't say how easily they break...or how long it takes... as I'm sure some folks don't have problems with them at all.

Say for instance - you're on a boulder and trying to climb it. You're having a bit of trouble. The amount of torque being applied to the axle/suspension/block is a lot. I think the blocks are the weakest link......and perhaps over time, they can develope cracks and break.
The guy whom almost got castrated.....the truck was attempting an obstacle and in movement (so to speak). The torque was too much and the block just broke in half and flew out under the torque.

If ya gotta have blocks - get steal ones (not alluminum). Welding them to the spring perches is probably a good idea also. But - seriously - wait till some other folks chime in.

Thanks Janster. So you would advise against the blocks from Toytec as they are aluminum: http://www.toyteclifts.com/0507tacocart.html#0507tacorearliftopts?
I thought that many people here have the Toytec blocks. Anybody with problems? What would be a good place to get better blocks?

Thanks!

Thanks for the advice. I will not be doing any rock hopping, just general offroad stuff. Steel vs. aluminum, I see alot of members have aluminum, why not more with steel/iron blocks?
