I use Estes Express (estes-express.com) on almost all of my shipments.  I’ve used UPS LTL and other companies, but they almost always try to add charges after the freight was delivered.

Try Dave Larson of TAG Shipping Solutions.

Try your local FASTENAL

Last time I used them to ship 2 karts on top of each other on a crate

And it only cost me less than $250

It only took a week to go from Cali to Missouri. My 2 cents. FastFreddy.  ;)

I would also recommend Dave Larson of TAG Shipping.  I use him for all my LTL freight.  Good prices and he’s a karter.

Tony and Tim have a valid point, and I agree with them also.

It’s always a great idea to support fellow karters, racers, business and local shops.

Those are also great options, and it will benefit us all. My 2 cents.  ;)
