Purchased this kit for a china pit bike I got for free.

Fast Delivery, Good Packaging

Engine light is now off.

Fit very nicely, it fit like a factory one and the craftsmanship it very detailed. Would highly recommend Walker products.

Everything worked very well. Before attempting installation, be sure to check if the wrist pin is installed in the piston and connecting rod. I will continue to purchase parts from this brand.

Easy swap, works flawlessly on my bike. This replacement has outlasted the OEM starter.

Impressed by the quality of these mirrors for my CBR600F4! The build is solid, they look sleek, and installation was a breeze. Highly recommend!

Impressed by the sun visor for my Highlander! Solid build, the gray color matches well, and the light is a handy addition. A great buy!

The BMW charge pipe hose got here in no time, securely wrapped and ready to install. Great service!

I’m amazed by the quality of this adapter. It’s sturdy, easy to install, and has kept my check engine light from coming back on.

This catalytic converter set for my 2010 Jeep Wrangler is outstanding. Sturdy build, perfect fit, and it's kept my engine running clean and efficient.

I’m really impressed with the quality of these connectors. They fit perfectly, are durable, and have made my 2007 Mountaineer run smoothly.

I'm extremely satisfied with the quality of these injectors. Sturdy and reliable, they've made my 2012 Mule run smoother than ever.

Excellent resolution for the Check engine Light.
