Antrys 2.5° Universal Axle Shims – Pinion Angle Correction for Leaf Springs & Lift Blocks (2 Pack)

Enhance lifted performance with Antrys 2.5° Universal Axle Shims

Raising a vehicle changes the drivetrain geometry, which can introduce unwanted vibration and wear. Antrys offers a precise 2.5-degree shim pair designed to work with standard single-pin blocks and 2.5" leaf springs. Made from billet aluminum and finished in a corrosion-resistant black, these shims are built to withstand demanding road and off-road conditions while helping maintain proper alignment.

Real-world use often involves mixed driving scenarios—daily commutes, trail climbs, and highway stretches. The 2.5° shims provide a reliable option to adjust the pinion angle without large hardware swaps, giving you a potential improvement in smoothness and drivetrain feel. The result is a more controlled ride with the potential to reduce noise and vibration that can travel through the driveline.

Key benefits at a glance

• Corrects 2.5° pinion angle on lifted suspensions for improved alignment.
• Eliminates driveline vibrations that can accompany taller setups.
• Protects differential pinion bearings and related components from premature wear.
• Supports longer drivetrain life with a durable, precisely machined shimming solution.

Universal fit and reliable construction

• Universal compatibility with standard single-pin blocks and 2.5" leaf springs, including a wide range of makes and models.
• Precision angle correction achieved through machined surfaces for consistent contact with leaf springs and blocks.
• Engineered to minimize slippage, maintaining alignment under heavy use.
• Billet aluminum with a black anodized finish for corrosion resistance and longevity.

What you get and installation notes

Each pack includes two 2.5-degree shims. Note: Extended center pins are not included and factory pins are typically sufficient for installation. The design supports stable contact and reliable performance across years of use.

These shims offer a practical option to fine-tune suspension geometry, potentially improving ride feel and drivetrain confidence without large, invasive changes. They’re a solid upgrade for riders seeking a measured approach to pinion angle correction.
