Finally, a permanent solution for a broken wing elevator. Don’t risk corrosive and flammable Pentosin® fluid leaks into the carbon fiber engine bay or rear quarter panels.
We offer the only PERMANENT SOLUTION for the overly complex and troublesome factory hydraulic mechanism.
Your Porsche® dealer wants $30,000 to
replace the hydraulic mechanism!
LOOKS AND FUNCTIONS EXACTLY THE SAME as the factory’s overly complex elevator mechanism. The world’s ONLY patented, economical and permanent solution for a fully functional wing! The Carrera GT eRam Kit™ consists of two self-contained electric rams that replace the unrebuildable hydraulic cylinders within each wing upright. The entire hydraulic system is removed to save precious weight. Upgrade from the troublesome factory hydraulic mechanism to the safer, simpler, lighter yet more robust eRam Kit™.
NO MORE HYDRAULICS!™
This is the overly complex and troublesome factory mechanism (note left elevator does not go up):
All of this is replaced with our lighter, more robust and unique electric eRam Kit™
The Carrera GT eRam Kit™ consists of two self contained electric rams, fittings, fasteners and electrical connections. The center sliding plates are slightly modified – but this does not prevent return to the hydraulic rams in the future. Easily maintained – no special tools needed – eRam Kit™ parts are simple to replace.
HEAVY DUTY yet light weight, the eRam Kit™ has two built-in limit switches within each electric ram. Functions exactly like the factory system; extends by using the dash switch or by reaching the wing deployment speed. Retracts with the dash switch, or upon slowing to the wing retract speed. If any of 4 factory limit switches fails (as they do) – the electric ram contains a back up switch!
COST EFFECTIVE – our eRam Kit™ is far less expensive than a new factory set ($24,500) – and will NEVER leak or fail due to the multiple problems associated with the OEM hydraulic mechanism. We have carefully identified over 13 failure mechanisms, which can be reviewed HERE. Installation of the eRam Kit™ is straight forward. No electrical modifications – plugs into existing electrical connections.
SIMPLER – MORE ROBUST – LIGHTER – SAFER
- World’s ONLY PATENTED all-electric wing actuation system.
- Cost Effective! – The dealer charges $30,000 to replace the OEM hydraulic elevator system!
- Robust – the self contained rams are designed for desert use and have a duty cycle equivalent to stroking every 6.5 minutes for 10 years!
- Works EXACTLY like the factory system: Up at 75 MPH, down at 37 MPH, or by using the dash switch to raise and lower.
- Lighter Weight – Saves PRECIOUS WEIGHT at the very top and back of the Turbo – 1/3 LIGHTER compared to the OEM hydraulic mechanism. Reduces center of gravity at the very back of the Turbo!
- No Worries – two year limited warranty – details HERE.

Calculation of Duty Cycle
The patented eRam Kit™ is designed for fairly harsh environmental conditions. If you used your car as a daily driver 5 days per week, and took 4 trips per day on a highway so the rams cycle 8 times, that would be 2,000 cycles per year, or on average 0.23 cycles per hr on average.
The eRam Kit™ has a very conservative 25% duty cycle. Thus, you would be able to safely cycle the wing 300 times per hour. In effect, there is a 1300:1 safety factor on an already conservative duty cycle.
High Speed Testing
Rennkit™ has been providing the eRam Kit™ for over 5 years to the delight of Porsche® owners around the world. The eRam Kit™ performs as designed at many high speed track trials (over 200 MPH in a modified 997 Turbo)! Many eRam Kit™ installation are on Turbos that are tracked. Wing operation is stable with smooth and precise actuation. Street or track, operation is exactly the same.
Center Sliding Plate Modification
The bore has to be minimally modified on one side of central hole. This does NOT affect re-installation of the hydraulic rams in the future. Rennkit™ can modify the bore, or you can take to the sliding plates to your shop for modification using our CAD prints. We offer either solution!
We do recommend you hold on to the old hydraulic setup – put it in a waterproof plastic container – include it with the sale of your Carrera GT should you ever sell the car! Rennkit can return your elevators to the hydraulic rams should that be a requirement of vehicle sale – AT NO CHARGE! That is how confident we are with our patented eRam Kit™.
OPTION 1: COMPLETE SOLUTION INCLUDING MACHINING
Remove 2 hydraulic lines and ship both elevator mechanisms to Rennkit. We machine (completely reversible back to factory hydraulics), assemble, bench test and ship back the entire assembly with the eRam Kit™ installed – ready to mount in the car. Complete illustrated step by step installation instructions sent with order.
Approximately 3 to 5 week turn around for this service.

OPTION 2: DIY METHOD
eRam Kit™ sent to customer. Customer has hole on center sliding plate bored out per Rennkit™ CAD drawings.
Approximately 2 to 3 week turn for this option 2.
