MR129 Low Profile Knee Bolster | Mercedes-Benz R129 — Ready-to-Install

More leg room. Factory-inspired fitment. Available fully finished and ready to install.

The MR129 Low Profile Knee Bolster is a redesigned driver-side knee bolster developed specifically for the Mercedes-Benz R129.

It reduces the overall profile of the factory driver-side knee bolster to provide additional leg and knee clearance while maintaining a clean, integrated appearance within the original interior.

Designed for taller drivers, modified seating positions, or anyone who simply wants more room behind the wheel, the Low Profile Knee Bolster creates additional usable space without leaving the lower dashboard looking unfinished.

DESIGNED FOR MORE LEG ROOM

The factory R129 driver-side knee bolster occupies a considerable amount of space underneath the dashboard.

The MR129 Low Profile Knee Bolster reduces this profile to create additional usable clearance around the driver's legs and knees while retaining a finished lower-dashboard appearance.

This makes it particularly useful for taller drivers or owners looking to maximize cockpit space without simply removing the factory knee bolster.

FULLY UPHOLSTERED — READY TO INSTALL

Select the Fully Upholstered option if you want the finished version of the MR129 Low Profile Knee Bolster.

Rather than receiving components that still need to be taken to an upholstery shop, the bolster is professionally wrapped and completed before shipment.

The fabric covering gives the knee bolster a refined, finished interior appearance while maintaining the additional leg clearance provided by the low-profile design.

No additional upholstery work is required.

Receive the completed bolster and proceed directly with installation.

ORIGINAL MR129 DESIGN

The MR129 Low Profile Knee Bolster was developed to solve a simple problem: create more usable driver leg room inside the R129 without making the interior look unfinished.

Instead of removing the factory knee bolster completely, the MR129 design retains a finished lower-dashboard appearance while reducing unnecessary bulk.

More room where you need it. Finished like it belongs there.

Designed from the R129. Designed for the R129.
