Heavy Duty Center Mount for MarRack Steering Rack

Update 2/13/2026: This product is now included with RCLT HD 💪🏽

v1.01, 12/7/22

Optional mid-rack reinforcement for RCLT HD. The 200-series Land Cruiser rack used to create a MarRack (patent no. 11066099) features a unique center mounting provision. This kit ties that provision into the sub-frame with a 5/16 in (7.94 mm) plate, creating a third load path between rack and frame.

By engaging the rack’s center bosses, this mount stabilizes torsional twist and side-to-side shove that normally act only on the main mounts. It complements our oversized M14 hardware and double-shear caps by giving the system a braced center spine.

Designed specifically for MarRack installs; not compatible with factory steering racks.

Why add it

Controls horizontal forces that try to shift the rack sideways under hard impacts.
Shares torsional loads so twisting is not carried only by the main bolts.
Spreads stresses across the frame, increasing mount durability over time.

Recommended use

Entirely optional. Install it if you want maximum rack-to-frame rigidity and redundancy. Many RCLT HD builds run it for peace of mind.
Straightforward installation during or after RCLT HD installation.

Field-tested since April 2022 on multiple Moab trails, the Dusy/Ershim, and Rubicon with RCLT HD + 40 in tires.

Note for Tacoma owners: Requires cutting off your center jack-point bracket as shown on Page 2 of the instructions.

For the ultimate steering rack connection, combine this kit with our Double-Shear Mount Upgrade. Together they create three reinforced load paths — vertical, horizontal, and torsional — giving the MarRack a rack-to-frame connection unlike anything Toyota or Lexus ever offered from the factory.
