FKBYM 2.5-Degree Pinion Angle Shims – Universal Suspension Axle Shims for Leaf Springs & Lift Blocks (2 Pack)

Elevate drivetrain alignment with precision shims

The FKBYM 2.5-Degree Pinion Angle Shims deliver a practical solution for aligning your axle when you lift, level, or reconfigure leaf springs. This two-pack uses durable billet aluminum with an anodized black finish, built to stand up to off-road and daily driving alike. While you experiment with ride height and geometry, these shims provide a straightforward way to refine pinion orientation and support a smoother driveline feel.

Designed for versatility, these shims fit a wide range of pickups and SUVs that use standard single pin blocks. They’re compatible with brands such as Ford, Chevrolet, GMC, Dodge, Toyota, Suzuki, Jeep, Nissan, and more, making them a practical upgrade for many builds. The shims are sized to a length of 12.5 cm and a width of 6 cm, with a 2.5-degree correction that you can add to the existing block setup.

Key specifications and installation notes

• Specifications: length 12.5 cm; width 6 cm; 2.5 degree angle correction
• Material and finish: billet aluminum, anodized black for lasting durability
• Compatibility: fits most models with standard single pin blocks and 2.5 degree shims
• Installation: extended center pins are not included; ensure your factory center pins are long enough
• Durability focus: engineered to help correct angle and may reduce driveline vibrations

In practice, these shims offer a practical option for drivers who notice changes in driveline behavior after a lift or suspension tweak. While not a guarantee, the angle correction and rigid construction are designed to support more consistent driveline geometry and potentially quieter, more confident highway or trail performance.

What you may experience

• Improved pinion angle alignment when altering ride height or axle positioning
• Better overall drivetrain consistency due to controlled angle correction
• Enhanced durability with a billet aluminum build that resists wear
• Broader compatibility across popular truck and SUV models with standard pins

With a two-pack in the box, you have flexibility to fine-tune or keep a spare on hand for future adjustments. This is a supportive upgrade for those who value thoughtful suspension geometry without overpromising results.
