Brand new turbocharger repair kits for diesel turbo rebuilds supplied by UPAPSI

Turbo Repair Kits

New Turbocharger Rebuild Kits for Holset, Garrett and BorgWarner Diesel Turbos

A turbo repair kit contains all the wear items needed to rebuild a turbocharger without replacing the complete unit — journal bearings, thrust bearings, thrust collars, piston ring seals, O-rings, snap rings and gaskets packaged together and matched to a specific turbo model. When the turbo's CHRA has worn bearings or leaking seals but the wheels and housings are still in spec, a repair kit is the cost-effective path back to full function. We stock brand new repair kits for Holset, Garrett and BorgWarner turbochargers across the full range of heavy-duty and medium-duty diesel applications: Cummins, CAT, Detroit, Ford, MaxxForce and more. Each kit is matched by turbo model and part number. US stock, no core charge.

Every Wear Item in One Box, Matched to Your Turbo Model

Turbo rebuild work starts with the repair kit — the bearings, seals and thrust components that bring a worn CHRA back to spec. Getting the right kit for the right turbo is step one. We stock kits matched to the specific turbo model so every component in the box fits the turbo on the bench.

Every Wear Item in One Box

Every repair kit includes the full set of serviceable components: journal bearings, thrust bearing, thrust collar, compressor-side and turbine-side piston ring seals, O-rings, snap rings, and the gaskets needed to reassemble the CHRA. Nothing to source separately — open the kit, rebuild the turbo.

Bearings, Seals, Thrust Components and Gaskets

Repair kits are turbo-model-specific. The HE300VG kit, the HE400VG kit, the GT3782V kit and the S300V kit each contain different bearings, seals and thrust components sized for that turbo's shaft diameter, bearing housing bore, and seal groove dimensions. We match by turbo model and OEM kit part number.

Kit Rebuilds Make the Math Work vs Full Replacement

We stock kits for the Holset HE and HX series, Garrett GT and GTP series, BorgWarner S300, S400, B2UV, K03 and other common turbo families. Twenty-six kit configurations cover the most commonly rebuilt turbochargers in North American diesel service.

Matched by Turbo Model and Kit Part Number

A repair kit costs a fraction of a complete turbo. When the wheels and housings are in spec, rebuilding with a kit saves hundreds to thousands of dollars compared to a full turbo replacement. The kit makes the rebuild economically viable — which is why turbo rebuild shops exist.

Twenty-Six Configurations In Stock

Repair kits are the highest-volume turbo part category we sell. Rebuild shops consume them faster than any other component. Consistent wholesale pricing, US inventory, and fast dispatch keep shop shelves stocked. See the wholesale page.

The Foundation of Every Turbo Rebuild

One-year warranty on every repair kit. See the warranty page.

FAQ

A typical turbo repair kit includes: journal bearings (the main bearings that support the shaft), thrust bearing and thrust collar (the components that control axial shaft movement), compressor-side and turbine-side piston ring seals (the seals that prevent oil leakage), O-rings, snap rings, and reassembly gaskets. The exact contents vary by turbo model — each kit is designed for a specific turbo family.

A repair kit is the right choice when the turbo has worn bearings (shaft play) or leaking seals (oil consumption, blue smoke) but the compressor wheel, turbine wheel, and housings are undamaged and within dimensional tolerance. If the wheels show FOD damage, the housings are cracked, or the shaft is scored, a complete turbo or additional components beyond the kit are needed.

By turbo model and kit part number. The turbo model (HE300VG, GT3782V, S300V, etc.) identifies which kit family you need. The part number on the original turbo's dataplate confirms the exact variant. Send us either identifier and we confirm the correct kit.

No. Repair kits contain wear items only — bearings, seals, thrust components and gaskets. Wheels, housings and shafts are separate components. If the wheels need replacement, order them individually alongside the repair kit. We stock compressor wheels and turbine wheels for the same turbo models.

All kit components are 100% brand new. No reconditioned bearings or reused seals. OEM-spec dimensions, one-year warranty.

Yes. Rebuild shops consume repair kits in high volume. Consistent wholesale pricing from US stock. See the wholesale page.

Turbo Repair Kit Guide

A turbo repair kit is the foundation of every turbocharger rebuild. Understanding what the kit contains, when a rebuild makes sense versus a full replacement, and how to match the kit to the turbo helps shops make efficient sourcing decisions.

What Each Component Does

ComponentFunction
Journal bearingsSupport the shaft radially — the main wear item that develops clearance over time
Thrust bearing + collarControl axial (end-to-end) shaft movement — prevents the wheels from contacting the housings
Piston ring sealsPrevent oil from leaking past the shaft into the compressor or turbine housings
O-ringsSeal the bearing housing to the turbine and compressor housings
Snap ringsRetain bearings and seals in their bores
GasketsSeal oil inlet, oil drain and housing joints during reassembly

Rebuild vs Replace: The Decision Framework

A turbo rebuild with a repair kit makes sense when bearing wear or seal failure is the primary problem and the rest of the turbo is structurally sound. Check three things before committing to a kit rebuild: inspect the compressor and turbine wheels for blade damage (chips, erosion, FOD marks), measure the wheel-to-housing clearance in both housings, and check the shaft for scoring or discoloration. If all three pass, the kit rebuild is the right path. If any component fails inspection, order the additional parts alongside the kit — or consider a complete turbo replacement if multiple components are compromised.

Rebuild Quality Depends on the Kit Quality

The bearings, seals and thrust components in a repair kit are the parts that determine how long the rebuilt turbo lasts. Low-quality bearings develop clearance faster. Cheap seals lose tension sooner. Undersized thrust components allow axial play that wears the entire rotating assembly. Every kit we sell uses components manufactured to OEM dimensional specifications — the same tolerances the turbo was built with originally.
