4WD Front CV Axle Shafts Pair for Chevy GMC 6-Lug Models

In this review of the Detroit Axle front CV axle shafts pair, the bottom line is simple: it is a practical replacement kit for owners of 4WD Chevrolet, GMC and Cadillac trucks and SUVs with 6-lug wheels who need correct fit and straightforward installation. The kit includes two front driver and passenger side CV axle shafts with a 21' overall length and bolt-on 6-hole inner spline, and it stands out most for its fit and ease of installation while offering a long 10-year warranty as assurance of replacement coverage.

Key Features

• Vehicle fit: Designed specifically for 4WD models with 6-lug wheels, so users get a direct-fit replacement for the listed Chevy, GMC and Cadillac models.
• Complete pair: The kit includes two front CV axle shafts, providing both driver and passenger assemblies for a full axle service in one purchase.
• Axle dimensions: With a 21' overall length and 33 outer splines, technicians can rely on consistent sizing for the specified models.
• Bolt-on inner spline: The inner spline uses a bolt-on 6-hole configuration which matches factory-style hubs on compatible vehicles for easier mounting.
• Long warranty: A 10-year warranty offers long-term coverage that can ease concerns about initial defects or premature failures.
• Brand reputation: As an aftermarket replacement assembly, it focuses on fit and function to restore driveability quickly.

Who It's For

This kit is for DIY mechanics and independent shops working on 4WD Chevrolet Silverado, GMC Sierra, Cadillac Escalade and related SUVs and pickups that specifically have 6-lug wheels. If the vehicle matches the year and 6-lug fitment notes, the pair is a convenient way to replace worn or damaged front CV shafts and get the truck back on the road.

It is not suited for 2WD models, vehicles with non-6-lug wheel patterns, or users who require OEM-branded parts for warranty or original equipment confirmation. Those seeking heavy-duty commercial replacements for extreme-duty towing beyond the listed K2500 7200 lb GVW fitments should consider purpose-built heavy-duty driveline components instead.

Pros & Cons

• 10-year warranty: long warranty period provides additional reassurance against early defects.

Cons

• Durability concerns: multiple reports indicate some assemblies came apart in use, so long-term reliability can be variable.

Yes. They are specified for 4WD Silverado 1500 models with 6-lug wheels in the listed years; confirm year and lug pattern before buying.
