Looking for GM Torsion Bar Specs - Help Needed!

I’m diving into some suspension work on my GM truck and I’ve hit a bit of a wall. I’m specifically looking for the torsion bar specifications for different GM models. Here are some details I’m hoping to get help with:

What I’m Looking For:

  • Dimensions: Length and diameter specifics of the torsion bars used in various GM models.
  • Weight Ratings: Are there specific weight capacities I should be aware of? I want to make sure I choose the right one for my build.
  • Application Models: Which models used what specs? I’m particularly interested in 1500 and 2500 series trucks.
  • Replacement Options: Any recommendations on aftermarket options or brands that are reputable?

Why It Matters:

Getting this right is crucial for the performance and safety of my truck, as I plan to use it for both daily driving and some light off-roading.

Additional Info:

If anyone has experience with this, or knows where to find a detailed guide or reference spec sheet, I would greatly appreciate any input! It would save me a lot of trial and error, and ensure I get the best setup possible.

Thanks in advance for any help!

Hey everyone! I’m looking for information on GM torsion bar specs. Can anyone share dimensions and load ratings?

The load rating usually varies based on the model. For example, the torsion bars used in the Chevrolet Silverado can handle about 1,300 to 1,600 lbs. What vehicle are you working with?

I can chime in! The dimensions for popular GM torsion bars are generally around 1.25 inches in diameter. Make sure to check the specific application though.

Good point! I’ve seen some models use different diameter bars, like 1.0 inches. Compatibility really matters!

Just to add, GM torsion bars are typically made from high-strength alloy steel. This enhances durability and performance.

That’s important information! Has anyone found differences between OEM and aftermarket torsion bars?

I’ve noticed aftermarket bars often have slightly different ratings. It can lead to compatibility issues, so research is key!

That makes sense! What about the adjustment range? Does it vary widely?

The adjustment range can vary based on the specific vehicle setup. Generally, you can expect around 2-3 inches of travel. It’s very model-specific!

Isn’t it wild how a small piece can make such a big difference? I sometimes joke that torsion bars are the unsung heroes of suspensions!

Haha, that’s true! The little things do matter. We should also think about the life expectancy of these bars.

Definitely! Typically, if maintained well, they can last for over a decade. Just keep an eye on those torque settings!

I’m also looking for the specs for GM torsion bars. Adjusting them can be tricky without the right numbers. Anyone has the specifics?

Adjusting torsion bars can be a bit of a challenge. I recommend using a torque wrench for precision. It makes a big difference!

Totally agree! I’ve had my fair share of struggles with it. Patience is key!

Check the mounting points and ensure they are not rusted. This can lead to challenges during installation. Best to avoid, trust me!

So, is there a specific torque setting for different models? I’m working on a 2000 Chevy pickup and could use some guidance.

I’ve worked on that model! For a 2000 Chevy, you should aim for around 35 ft-lbs on installation. Always double-check the manual too!
