Bearing Carrier TLZ for X4 Jacob's Ladder Left

• Fits Z-link (trailing arm) rear configuration. Does not work with wishbones. Fits Hyper X4 and other manufacturer's Chassis. 
• Fits 1-3/4" axle.
• 4-1/2", 5" and 5-1/2" spread.

We recommend the bearings be greased before the first use with DAYLube™ High Performance Grease 77-800 & 77-805. 

Uses (1) 7/16-20 x 2-3/4" HHCS with (1) 7/16-20 nylock half nut for the torsion arm bolt, (2) 5/16-18 x 2" SHCS for standoff.
