I'm going to be using my blazer for hauling cars on a dual axle trailer. I just was wondering if anyone knew if the leaf springs off a 2500 or 3500 would bolt up without any modifications. My other option was doing an add a leaf kit. I'm just looking for some more support in the rear. I found an add a leaf kit for $45. I think a new leaf set from pull apart would prolly cost the same. Anyone have any tips?

Thanks!!

 

The Blazers are not rated for pulling that much weight. I think the max is about 3500 LBS. Once you have your 1000 lb trailer and a 3500-4000 lb car your going to kill the transmission. You would be better off getting a full size 1/2 ton truck. Plus that much weight would push you all over the road. Its not so much a matter of going as it is stopping. These are basically 1/4 ton vehicles.

 

I am pretty sure that the springs under a fullsize truck are longer.

 

Hmmm, he could pull it.

My 2000 Blazer manual says with a 4x4 auto 3.42 gears, I can tow up to 5600lbs.
Install a trans cooler and go the extra mile and get a trans temp gauge.
Stopping? Get a trailer with electric brakes.

You may not need to add more leaf springs. If your trailer is dual axle, and loaded CORRECTLY, you can keep the tongue weight down.

 

i would be very supprised if you could fit those spring under there.

 

The S10's came with an upgraded spring package. If you look around in the salvage yards you might can find them. Look for RPO Code Z85. These have a stiffer rear spring. These will bolt right in.

 

I'm pretty sure you are right.

 

Thanks for all the replies. Our trailer is a double axle with brakes. Just put a new set of shiny brakes on, and plan on replacing them often. Stock torque converter was going, so when I rebuilt the engine, I put in a beefier one.

 

maybe just add some new coil over shocks on the back. They add about 1200 lb of extra support and still ride nice. i just put them on my blazer and they are awesome. I got monro sensatrak coil over.
