January 15, 2006I have a 2001 half ton chevy Z71 with a 6" lift on 33" tires. I bought the truck mainly to tow my trailer, a 28 foot toybox. I have tried to find out what the difference between a 1/2 and a 3/4 ton truck is but am unsuccessful in aqcuiring that. My main question is if I change to a higher gearing in my rearend if that will increase my towin capacity or will also need to change the axle and tranny?.. also does it being a Z71 make the towing capacity go up from the stock chevy truck of 7300#??? Thanks for any help you could give me.

February 24, 2006I HAVE A 2500 SUBURBAN. IN 2000 THE ACTUALLY BEEFED UP THE FRAMES ON THE 2500 QUITE A LOT....THAT IS ONE BIG THING. NO MATTER WHAT GEARING, OR ANYTHING YOU DO OR HAVE CHAGED....YOU WITH BEND OR TWIST YOUR FRAME IF YOU OVER DO IT...YOU EVER NOTICE HOW A LOT OF F150'S OLD OR NEW HAVE ALMOST A "V" TO THE BODY, AND THERE IS AN UNEVEN GAP BETWEEN THEIR CAB AND BED?. YEAH....THEY FOUND OUT THE HARD WAY. THEY ARE INFAMOUSE FOR THAT WHEN OVER LOADED. BEING A Z71 IT DOES HELP IT FOR SUSPENSION SAKE. BUT THAT IS ALL A Z71 IS MOSTLY...SUSPENSION...WHICH IS GOOD, DON'T GET ME WRONG, I WISH THEY MADE A 2500 Z71 HAHA. BUT SOME PEOPLE THINK IT MEANS A LOT MORE. THERE ARE A FEW DIFFERENCES BETWEEN 2500'S , BUT THE BIG THING IS THE HEAVIER FRAME. THE GVW (GROSS VEHICLE WEIGHT) IS OVER 3,000-5,000 (2500 OR 3500) LBS MORE THAN THE 1500. PLUS THE FACT THAT THEY HAVE THE 6.0 LITER ENGINE THAT HAS MORE HP AT LES RPM'S HELPS TOO. YOU SHOULD BE ABLE TO MOD YOUR TRUCK TO DO THE JOB, BUT DON'T OVER DO IT, OR THINK IT CAN DO WHAT THE 2500/3500'S DO OR YOU'LL BE LOOKING LIKE THE FORDS HAHA.
February 24, 2006The rated towing capacity of a vehicle is consistent with the strength of the chassis. That's why the trucks are rated 1500, 2500, 3500 and on, not to leave Ford people out, 150, 250, 350, 450(Super Duty) and on.... In order to beef up the towing capacity you have to strengthen the chassis. On the 1500 your best bet would be to 'box' the frame. If you look at, let's say, a GM 3500 4X4 youâ€™d notice that the chassis is actually doubled. It looks like a smaller chassis inside a larger one. This way they don't have to 'box' the frame and can leave it open to make it easier run wires, brake & fuel lines, hoses and such. Once you beef up the chassis, then, start looking at making more horse power and changing the gearing to tow more weight. Just upping the horses and lowering, (I consider going from 373's to 411's 'lowering'), the gearing will definitely allow you to pull greater loads, but it will also tear you truck apart if not strengthened to carry the load ........
