Overview

Replacing worn carrier rollers before they cause severe damage to your track group is just good maintenance. Designed as a direct drop-in replacement, our aftermarket D6R top roller ensures your bulldozer maintains proper track tension and alignment, preventing the chain from sagging during heavy earthmoving tasks.

Why Choose SQ Carrier Rollers?

We know that equipment downtime costs you money. Instead of using generic marketing claims, here is exactly what you get when you install our rollers:

  • Exact OEM Fitment: Machined strictly to CAT 6Y1781 and CR4800 specifications. No modifications needed—just bolt it on and get back to work.

  • Built for the Abuse: Forged from heavy-duty steel and deep-induction heat treated. This provides a tough outer shell to resist abrasion while keeping the core flexible enough to absorb impact shocks.

  • Strict Quality Control: Every batch is tested for seal integrity and dimensional accuracy before it leaves our facility. We don't ship parts that we wouldn't use on our own machines.

Quality inspection of D6R XL bulldozer carrier rollers

Whether you are maintaining a single dozer or managing a large construction fleet, upgrading to a reliable aftermarket D6R top roller is a cost-effective way to extend the life of your entire undercarriage system.
