Porsche 991 GTS Control Arm Wheel Hub Front Rear Shock Absorber

For the Porsche 911 GTS (991 generation), the suspension and hub components are a mix of Carrera S parts and track-oriented hardware. Because the GTS features a lower ride height (PASM Sport) and a wider track, these components are precision-matched.

1. Control Arms (Wishbones)

The 991 GTS uses a reinforced lower control arm (often called a “coffin arm”).

• Front Lower Control Arm: * Part Number: 991-341-053-06 (or latest revision).

  • Price (2026): $430 – $550 USD (Genuine) / $250 – $320 USD (OEM like TRW).

• Rear Lower Control Arm: * Part Number: 981-331-053-02.

  • Price (2026): $420 – $490 USD.

• Aftermarket Upgrades: Kits from Elephant Racing or RSS that include monoball bearings and adjustable shims for track alignment typically cost $1,300 – $2,000 for a full front or rear set.

2. Wheel Hubs & Bearings

The 991 GTS is unique because many were ordered with Center Lock wheels. Hub replacement is significantly more expensive for Center Lock cars.

• 5-Lug Hub (Standard): * Price: $280 – $350 USD.

• Center Lock Hub (GTS/Turbo/GT3): * Part Number (Rear): 991-331-607-81.

  • Price: $390 – $480 USD per hub.

• Wheel Bearings: These are generally pressed into the carrier.

  • Front/Rear Bearing: $115 – $180 USD.

3. Front & Rear Shock Absorbers (PASM)

As established, the GTS uses PASM-specific dampers.

• Front Strut (PASM GTS): 991-343-035-48.

  • Price: $1,150 – $1,300 USD.

• Rear Shock (PASM GTS): 991-333-057-40.

  • Price: $850 – $1,050 USD.

• The “DSC” Upgrade: In 2026, many GTS owners install a DSC Sport V3 Controller ($1,450) instead of replacing shocks. It plugs into the factory harness and optimizes the existing dampers for better ride quality and track grip.

5. Critical Installation Note: The GTS Center Lock

If your GTS has Center Lock hubs, you must not apply anti-seize to the wheel mating surface, only to the threads and cone of the nut itself (using Optimoly TA).

• Torque Spec: $600\text{ Nm}$ ($443\text{ lb-ft}$).

• Hub Life: Porsche recommends replacing Center Lock hubs every $6,000\text{–}12,000\text{ track miles}$ or $60,000\text{ street miles}$ due to the extreme stress on the single locking mechanism.
