Chassis set-up blocks are adjustable in 1/4" increments, making it easy to dial in the perfect height for your rear axle.
The quick release pin holds the block at your desired height, ensuring a secure fit.
The contoured bottom surfaces of the blocks fit perfectly on steel tubing or any flat surface, and the magnets keep them securely attached to the chassis.
With Small blocks adjusting from 1.75" to 4", and Large blocks adjusting from 3" to 6", you have the flexibility to customize your set-up to suit your needs.
Perfect for front and rear axle setup.
