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

More leg room. Factory-inspired fitment. Designed to be upholstered just like the original.

The MR129 Low Profile Knee Bolster is a redesigned two-piece knee bolster developed specifically for the Mercedes-Benz R129. It reduces the overall profile of the factory 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 dramatically changing the character of the R129 interior.

The bolster is supplied as a physical 2-piece design consisting of separate driver-side and passenger-side sections. Each component is manufactured as a rigid base that can be upholstered using traditional automotive upholstery materials and techniques, allowing it to be matched to your existing interior.

Designed for More Leg Room

The factory R129 knee bolster occupies a considerable amount of space underneath the dashboard. The MR129 Low Profile Knee Bolster reduces this profile to create additional clearance around the driver's legs and knees.

The result is a more open seating area while retaining a finished interior appearance.

This is particularly useful for taller drivers or owners looking to maximize available cockpit space without removing the lower interior panels entirely.

2-Piece Construction

The kit consists of two individual knee bolster sections designed to replace the corresponding factory components.

• 1 × Driver-Side Low Profile Knee Bolster
• 1 × Passenger-Side Low Profile Knee Bolster

Both pieces are supplied as physical components ready for upholstery preparation and installation.

Upholstery & Finishing

The MR129 Low Profile Knee Bolster is designed to be upholstered in the same manner as a traditional automotive interior panel.

The rigid underlying structure provides the form, while your upholstery shop can apply foam, leather, vinyl, Alcantara, or another suitable automotive material to achieve the desired finished appearance.

This makes it possible to match the bolster to an original interior or incorporate it into a completely customized interior.

Professional upholstery is recommended for the best finished appearance.

Vehicle Compatibility

Designed for Mercedes-Benz R129 SL-Class models.

Please verify your vehicle's interior configuration before ordering. Differences in model year, trim, previous repairs, or interior modifications may require minor adjustment during installation.

Original MR129 Design

The MR129 Low Profile Knee Bolster was developed to solve a simple problem: create more usable space 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 while reducing unnecessary bulk.

More room where you need it. Designed to look like it belongs there.
