Complete Undercarriage Systems & Assemblies
Need a full undercarriage rebuild? When your dozer undercarriage has reached the end of its service life across multiple component categories, sourcing every component individually takes time you may not have. EquipXR offers complete undercarriage systems that are designed to be installed as a unit. Full assemblies simplify procurement, ensure component compatibility, and help you return a machine to service faster. Contact our parts specialists to configure the right assembly for your machine and application.
Idlers – Front Idlers, Rear Idlers, & Idler Assemblies
Dozer idlers guide the track chain and help maintain proper alignment and tension. Worn idlers accelerate track wear, which means premature failure across your entire dozer undercarriage system. EquipXR stocks front and rear idlers for all major dozer brands, engineered to match the original dimensions and mounting specifications, ensuring a direct bolt-on fit with no machining required.
Rollers – Track Rollers & Carrier Rollers
Track rollers and carrier rollers keep your dozer riding level and distribute the machine’s weight evenly across the track. Worn rollers cause premature track and frame wear, increasing your total undercarriage cost over time. EquipXR stocks both single-flange and double-flange bottom rollers, as well as top rollers (carrier roller), in a wide range of configurations to match your specific machine. All are sealed and lubricated for extended service intervals.
Sprockets & Segments
Sprockets and bolt-on segments drive your track chain, and worn teeth accelerate wear across your entire undercarriage system by chewing through your bushings, links, and shoes. EquipXR offers both complete sprocket rims and bolt-on sprocket segments for easy field replacement.
Pins & Bushings
Track pins and bushings connect the individual links of the track chain and are subject to constant metal-to-metal contact and abrasive wear. They’re designed to be replaced before they begin causing damage to your track links. EquipXR carries both pins and bushings in standard configurations, individually and as matched sets, for all major dozer undercarriage systems.
Bogies & Bogie Assemblies
On older and certain specialty dozers, bogie assemblies replace individual rollers with a spring-mounted, multi-roller unit that distributes load and cushions impact. EquipXR stocks bogie frames, mounting hardware, and complete bogie assemblies for compatible machines, including select Liebherr, Komatsu, and specialty crawler platforms.
Final Drives
The final drive is the final piece of the chain between your engine and the track; it transfers torque from your powertrain to the sprocket. Final drive failures are costly and time-consuming, but proactive replacement of worn seals, bearings, and housings can prevent catastrophic breakdowns. EquipXR stocks complete aftermarket final drive assemblies as well as individual components, including drive motors, hubs, planetary gears, and seal kits, compatible with hydraulic and mechanical drive configurations.
Recoil Springs & Spring Assemblies
The recoil spring cushions the front idler against shock and maintains proper track tension. A failed or fatigued recoil spring leads to erratic track tension, accelerated wear, and potential damage to your idler and frame. Our recoil spring assemblies are manufactured to OEM load specifications, ensuring proper idler travel and consistent track tension absorption across the full range of operating conditions.
Grouser & Equalizer Bars
Equalizer bars distribute machine weight and allow the undercarriage to flex over rough terrain, maintaining ground contact and reducing stress on the track frame. Grouser bars add traction to track shoes and protect underlying components on low-clearance machines. EquipXR carries both to handle the equipment loads and impact forces that dozer work puts on these components.
Undercarriage Tracks & Complete Track Assemblies
When a dozer’s undercarriage has reached the end of its service life across multiple components, sourcing parts one by one is expensive and risks introducing mismatched wear into a freshly rebuilt system. A complete track assembly from EquipXR solves all of that at once.
Our complete track assemblies are fully matched sets (track chain, shoes, pins, bushings, and connecting hardware) and are configured to work together. Every component in the assembly is manufactured to consistent dimensional and material specifications, so wear rates remain uniform across the system and you get the maximum service life from every part. EquipXR’s complete aftermarket track assemblies are pre-assembled and ready to install, built to OEM specifications for a direct replacement fit.
Track Adjusters & Tensioners
Proper track tension is essential for minimizing undercarriage wear. EquipXR carries track adjuster cylinders, grease-type tensioners, and hydraulic track tensioner assemblies to restore correct tension adjustment function to dozers with worn or seized adjuster components. Our track adjusters and tensioners are built to the original stroke, bore, and seal specifications for a leak-free, fully functional replacement.
Track Chains, Shoes, Pads, & Links
Track chains, shoes, pads, and links make up the primary ground-contact system of your dozer, and the configuration you choose has a major impact on machine performance. EquipXR stocks standard triple-grouser steel shoes, low-ground-pressure (LGP) shoes, swamp pads, rubber pads, and bolt-on rubber track pad options across a wide range of widths and pitch configurations. We also carry individual chain links, master links, and shoe bolts so you can address localized damage without replacing an entire track assembly.
OEM-Equivalent Dozer Undercarriage Parts
EquipXR offers a full range of aftermarket dozer undercarriage parts that meet or exceed OEM specifications. Our parts are built for dependable replacement performance and sourced to align with OEM fitment requirements, dimensional standards, and material expectations.
For equipment owners and fleet managers, that means access to replacement parts that make practical sense from both a maintenance and cost standpoint. Our inventory of parts covers machines of all sizes, used in a variety of applications from earthmoving to mining.
Dozer Undercarriage Part Compatibility By OEM Brand & Model
EquipXR helps customers identify compatible aftermarket undercarriage parts across a broad range of OEM brands and dozer models. When available, details such as the make, model, serial number, and existing part numbers help narrow the selection and reduce the risk of ordering the wrong components. This is especially important for mixed fleets, older dozers, and machines that may have been rebuilt or updated with non-original undercarriage parts over time.

The service life of dozer undercarriage parts varies significantly depending on operating conditions, terrain type, and maintenance level. In average conditions, a well-maintained undercarriage can last 3,000 to 5,000 hours. In abrasive or rocky terrain, that number can drop to 1,500 hours or less. Regular inspections (ideally every 250 to 500 hours) can catch wear early and are one of the most effective ways to extend service life and keep replacement costs predictable.
