Introducing TKI CNC traction blocks. Constructed from 6061 billet aluminum, they are designed to work with most round, tube frame, running boards.
For maximum strength, the blocks use a pair of 3/16 pop rivets for mounting. Each block is drilled and tapped for a set of 10/32 “traction” screws. The blocks work great without the added traction screws, but we have found some harder soled boots require a more aggressive traction solution. Produced in two sizes 1 1/2 inch and 3 1/4 inch. The 3 1/4 inch blocks work great along the outside rail edge while the 1 1/2 inch are best suited for the inner crossbars.
Each kit includes 24 aluminum blocks (8 long and 16 short) all necessary mounting hardware and traction screws. Currently available in black.
