HOW DOES IT WORK?

FIND YOUR PARTS
Browse our site or use our Vehicle Search to find the right parts for your truck. Once you've confirmed fitment, select the Auto-Refill & Save 5% option from the product page.

PICK YOUR PLAN
We offer 3, 6, and 9-month plans for most of our products, and 6, 9, and 12-month plans for our premium beam wiper blades. We recommend every 3 months for heavy haulers, 6 months for daily drivers, and 9 months for trucks that only see occasional use.

SUBSCRIBE, SAVE, NO MORE WORRIES
Once you sign up for a Doc's Cruise Control Subscription Plan, you never have to worry about when you need to replace your parts. Once the box shows up on your porch, you know it's time for a change. You'll be notified before your order is processed in case you need to make any changes.
