I was thinking about getting a 1500 frame for my truck. I was thinking if it was 800lbs lighter that should be good for 4 tenths atleast. Anyone know the difference?

The problem here is you would have to fab LOTS of things to make it work and can a 1500 frame handle 530hp/1000ftlbs? our 3/4 frames already show distortion from a 500/1000 truck... ask TNRGREEN or Freighttrain I believe there was a thread about how much things move when pulling or racing. I would say it wouldn't be safe nor make it worth all the effort Anthony. Your better off adding about 5,000$ worth of parts and run mid to high 11's.

I was planning on making it stronger where it needs to be. And still trying to keep it light. What frame is the 1500 diesel going to use?
What would I have to fab. They should be very similar

Im sure the motor mounts are different... the 3/4 frame could be wider and longer than the 1500? Ask yourself the question for a mere 800lbs is it worth it? You will have to remove the cab... By all means you would be the first to do it but look at what guys are doing with 3/4 frames. 9 second ET's:eek: Im sure some of the smart minds here will give you all the info you'll need but again talk about hours of fabrication this isn't going to be a bolt on bolt off job but im sure you know that already:D Honestly you'd be better off selling your LMM buying a 1500 and transplanting an LBZ/LLM-6speed over to the thing.

From my understanding the 2500 frame is taller, thats it. What about everyone puting a dmax in a suburban?
I wouldnt think switching frames would be to difficult. But I have been wrong before :D

I don't think the the frame is that much lighter. Ive seen a 1500 RC/SB 4x4 with a 6.0 weigh 5000lb in street trim. Thats only a 1000lbs lighter than my RC/LB 4x4 Dmax/Ally.

To find out, go to Edmunds.com or other website with new vehicle data. Compare the weight of the 2500HD 2wd RC/LB with the 1500 2wd RC/LB with the V8 gas engines. Almost all the difference will be frame, since the engine and trans and bodies are the same weight.

The 1500 was only 500lbs lighter and it had the V6 :(
I thought it would have been more than that.

Yeah, but thats 1/2 a second right there.... free HP.

If you're going to build a 1500 frame, find one that has regular articulated-ball steering, not rack and pinion. Maybe a 4x4 frame? I know the 2wd R&P trucks have this gigantic forward crossmember that interferes with the front of the Dmax oil pan.
