rear suspension blocks?

[616samuel]

New to this site so sorry if it's been asked already, i did a little searching with no luck.

I pull in the "Stock class" with duramaxtuner.com's tunes, i have traction bars and bumpstops.

I was wondering if adding 1.5" to 2" blocks in the back would help at all with the added forward angle on it?

here's some links of last years pulls when i was running the ATS E-Power tuner on 315hp setting. it ran pretty good but i'm expecting alot better results this year with duramaxtuners tunes with a lift pump and MA built tranny and maybe bigger injectors.

This is my wife driving and ended up in 4th place after a pulloff for 3rd.

do you take yout t bolts out? that will help with the rake of the truck but
from the video looks like the truck plans out nice. i coudlnt tell much from the 2nd video.

I would not put the blocks in the back. The extra rake on the truck will not help enough when pulling off of a receiver hitch and can make it hard on the front end. JMO Should run good with the new tuning. Good luck.:thumb:

yea, t bolts let all the way out, Might be the weight brackets on the hot diesel class making the other GM's back ends look way higher than mine... i was just curious Thanks!

i run 2" x 3" rectangular channel, bolt it down to the bump stop plates on the axle housing.

the more level the better when using a reciever...my truck has the slightest rake to it even with 1,000lbs off the nose

I just installed the four inch turf country on my truck.. and running one inch blocks at the moment with caltracs that have a lot of preload.. should I do 2 or 3 or what?

Stick with the one inch blocks in the back. Try to get the chassis so that it sits level when the bars are down. Unless it looks really bad when you have the torsion bars turned up anyways. Good luck with it.:thumb:

Alright. Sounds good! Just wondered cause I'm pretty sure Tony b runs like 3 or 4 inchers...
