What is the purpose of an eccentric lockout kit?

An eccentric lockout kit replaces the factory eccentric bolts used for alignment adjustments. These factory bolts can slip under high cornering loads, causing your alignment to change. The lockout kit provides a more stable connection to keep your alignment settings consistent.

Do I need adjustable control arms to use this kit?

Yes, you will need adjustable control arms to set your camber and toe after installing this eccentric lockout kit. The kit itself eliminates the factory adjustment bolts, so you'll need other adjustable components to dial in your alignment.

What is included in the kit?

The kit comes complete with CNC machined T6061 aluminum lockout plates, zinc-plated grade 10.9 hardware, washers, and bolts for both the camber and toe arms on one vehicle.

Product Details

The stock eccentric bolts used for rear camber and toe adjustments on your 2003-2009 Nissan 350Z or 2003-2007 Infiniti G35 can slip under hard cornering, throwing off your alignment. This SPL Parts Eccentric Lockout (EL) kit replaces those factory bolts entirely, ensuring your alignment stays exactly where you set it. Keep in mind that to adjust camber and toe after installing this kit, you'll need adjustable control arms.

These lockout plates are CNC machined from T6061 aluminum, a strong yet lightweight material, and come with zinc-plated grade 10.9 hardware. This combination provides a zero-slip solution that holds your alignment steady, even under aggressive driving conditions. The kit includes all the necessary washers and bolts for both the camber and toe arms on your vehicle, making it a complete package for one car.

This kit is proudly made in the USA, ensuring solid construction and attention to detail. It's a straightforward way to maintain precise rear-end alignment, especially if you're pushing your car hard on the track or during spirited drives.
