I’m looking to lower my Chevrolet C1500 with a 4 to 6 inch drop and I’m planning to run 20-inch wheels. I know this is a popular setup, but I’m reaching out for some guidance before I dive in.

Here’s what I’m considering:

  • Parts Needed: What are the essential components for a proper drop? I’ve heard about drop spindles and coil springs but any specific brands or kits you recommend?
  • Installation Tips: I’m somewhat handy but have never tackled lowering a truck before. Are there any tips or tricks you can share that might make the installation process smoother?
  • Ride Quality: How does dropping a truck affect the ride quality? I want it to look great but also don’t want to compromise comfort too much.
  • Trimming Required: Will I need to do any cutting or trimming to fit the 20s after the drop?
  • Alignment Issues: Do I need to worry about alignment after the drop? What’s the best way to ensure it’s done right?

Any advice on:

  • Good suspension shops that specialize in these modifications?
  • Potential pitfalls or mistakes I should avoid?
  • Overall experience with driving a dropped C1500 on 20s?

Thanks in advance for your input! Looking forward to getting my truck looking good and riding right!

Hey! For a 4/6 drop on your C1500, I recommend Belltech drop shocks and spring kit. They provide a great balance of comfort and handling. Make sure to check the alignment after the drop to avoid uneven tire wear!

Thanks for the tip! Will these be compatible with my stock components, or do I need to upgrade other parts too?

You might need new sway bar links if you’re going with a significant drop. I used DJM control arms to maintain geometry and a smooth ride. Don’t skimp on the shocks—upgraded ones will last longer and perform better!

Great point! How about the alignment settings? Any specific specs I should aim for?

Usually, you want a little negative camber to help with cornering. -0.5 to -1.0 degrees is a good target. Don’t forget to check toe settings too—they need to be spot on after a drop!

Awesome info! What about the rear end? Will the stock parts work after the drop?

You might need to cut the stock bump stops for a proper fitment. I added a panhard bar to prevent rear lateral movement too. It really helps maintain stability post-drop!

Do you think going too low might cause issues with scraping on speed bumps or driveways?

10

Definitely! You might want to consider a set of airbags to help adjust the height when needed. Plus, you can have fun dropping it even lower at shows!

That sounds tempting! But isn’t that a bit overkill for street use? Trying to keep the budget in check here!

I hear you, budget is key! But think of it as an investment in your ride. Just remember, lower isn’t always better; too much can hurt handling, so balance is vital!

Hey there! For a 4/6 drop on 20s, I recommend 255/45R20 tires. They provide a good balance of clearance and a nice stance without rubbing.

14

That’s a solid choice! I also think that sticking with a tire brand known for quality like Michelin or Goodyear could help with performance.

15

Don’t forget about the wheel offset! A +30 to +40 offset generally works well with a drop. This can prevent issues with rubbing on the fenders.

I went with 275/40R20 tires after my drop, and they fit beautifully. Just ensure you have the right alignment after the drop too!

17

Right! Offset is crucial. Also, did anyone consider going with a staggered setup for added grip?

18

Staggered setups can be tricky! I’m leaning towards 255/45R20 for the front and 275/40R20 for the rear. That could work well on a C1500.

19

That sounds like a plan! Just make sure you check the clearance regularly—better safe than sorry!

I totally get the excitement! If anyone’s wondering, I’ve also noticed that minor adjustments in suspension can affect clearance with 20s.
