Rear Block Options?

mbrannon · May 4, 2009

OK.. I was screwed up on the hieght of the stock 07' rear blocks... they are not 2" as the Ready lift box claims they are 1.25"s ... I want to add about an inch to 1.225 inches of height to the rear of the truck. Ready lift sells a kit for 139 bucks... I've found a few blocks for $39 but no square ubolts... What gives? Is Ready Lift the only player in this market? Help a brother out... I've all ready installed the leveling kit up front so a total package is out of the question...

Has anyone had any dealings with the company I have linked above?

There is a truck shop in town here that will custom make u-bolts for you for about $15. If there's a truck shop near you, give 'em a call.

Thanks for the information. Although most will want the additional height, I'm really only looking to put an additional inch or so in height to the rear. Most more than likely I'm going to have the custom shop in the neighboring town make me a set of custom blocks and u-bolts. I put the ready lift leveling kit on the truck to get away from the severe rake look. I dang sure am not gonna spend hard earned green backs to put all of the rake back in. Having had back surgery in 05 the higher I make the rear of the truck the more trouble I have getting in and out of the bed, and the more likely I'll re injure my self.

Obviously you more than likely work for Ready Lift. The leveling kit is a great product. However, the vague advertising campaign and no model specific information available for the rear lift blocks leaves a lot to be desired.

Seeing that this weekend is Mothers Day I doubt I'll be doing any trruck work this weekend...

No experience with them but blocks are basically just spacers... I'd think as long as the bolts are good quality, you're on the way to stardom.

No - dont work for Readylift - but i did install the rear block on my truck - and they are taped slightly

the article was copy/pasted from their site - knowing there is alot of confusion for the blocks for the GMT800 to the GMT900 ..

yeah , the advertisement could use more clarity ,,

i just put the ready lift 2.25 leveling kit up front and the blocks yesterday. everything went smooth until i got to bolting the u bolts back on. it seems like the ubolts they supply could be used for a bigger block and the threads are long. it would have been way easier if i actually had an impact gun with a very deep socket. turning a wrench on very long fine threaded u bolts definatly sucks. it rides great though and feels great. can't wait for my new tires to show up

I think you will find that once you remove the factory blocks and measure them, that it is only a 1 inch block and not 1.25 inch. I took my factory blocks out and replaced them with a 2 inch block from Truxxx. It will give you an addtional 1 inch lift in the rear. If you go to Truxxx's website it will not show an option to buy just the rear blocks, but if you call them and tell them you want just the rear blocks, they will sell them to you....and there is a specific part number for them.

Also, the blocks from Superlift require you to stack them on top of your existing factory blocks.....IMO I would not stack blocks, most people advise against it.

Stock '07+ NNBS block vs. ReadyLift Block for reference. Replaced these at the same time I did the leveling kit up front and the truck sits with a slight rake like I wanted. I don't remember what the stock block measured (1" vs. 1.25"), but that's easy for anyone with a ruler to go out and check.

The supplied u-bolts are indeed way way long, and if you don't have air tools, well, GOOD LUCK! Your arms will most likely fall off using a socket wrench.

hell i didn't have a socket deep enough so i had to use a wrench, and yes my brother in laws and my arms just about fell off. just got my tires on today (285/70r17 terra grapplers). love the way it looks.
