Cylinder Service Options

We offer three rebuild options for your convertible top cylinders:

Option 1: We rebuild your cylinders.

You send us your cylinder(s). We rebuild your cylinder(s) and have them on their way back to you the next business day in most cases.

  • Porsche Carrera 996/997 cylinder typically require 5 business days to rebuild.
  • Cylinders that need rod replacements may take longer to rebuild.

Option 2: We exchange/swap your cylinders with rebuilt cylinders from our inventory.

We stock “ready to go” rebuilt cylinders for several makes and models. You ship your cylinders to us. Upon receipt, we inspect your cylinders for damages. If your cylinders are in good condition, we pull replacement cylinder(s) from our inventory and ship the replacement cylinders back to you the same business day in most cases. Contact us for cylinder availability.

  • We charge a non-refundable exchange fee when you exchange/swap your cylinders with ours.
  • If your cylinders are damaged, we will contact you about rebuilding your cylinders rather than exchanging/swapping them.

Option 3: We advance-ship rebuilt cylinders from our inventory.

Contact us for cylinder availability. If we have the cylinder(s) that you need in stock, when you place an order with us we ship our rebuilt cylinders to you from our “ready to go” inventory. Orders received by 3:30 p.m. EDT/EST typically ship that day; orders received after 3:30 p.m. EDT/EST ship the following business day.

When we advance-ship cylinders, we charge a refundable core deposit and a non-refundable exchange fee. When you send back your leaking cylinders, upon receipt we inspect your cylinders and process your core refund. Your refund amount will be impacted by the condition of your returned leaking cylinders.

  • Porsche Carrera Kits are currently unavailable for advance-ship.
  • Advance-ship cylinders are not available for international orders.

Call us for pricing:

Cylinder prices vary depending on the rebuild service option that you choose. Additional service fees apply for cylinder exchanges and advance shipment of rebuilt cylinders.

Also, if you are choosing to use our Hydraulics Hose Repair Couplers with your rebuild, please make sure that you let us know this when you call so that we can include the cost of the couplers in your quote.

Inspect your leaking cylinders before you ship them to us:

Know the condition of your parts!  Please inspect your cylinders very carefully before shipping them to us. Older model cars often have had more than one owner and previous attempts to repair the cylinders may have been made. Some cylinder rods are also prone to rust and pitting. Before sending us your cylinders, carefully look for missing parts, damages, or tampered-with cylinder components. 

Cylinders that were previously tampered with or altered may not be eligible for an exchange or core refund. Cylinders with rusty rods cannot be rebuilt properly without replacing the rods. If your cylinders are damaged, tampered with, missing parts, or are altered in any way, please call us to discuss your options before you ship them to us. In most cases we can still repair your damaged cylinders. Additional costs will apply based on the extent of the damage.

Include relevant information with your cylinder shipment:

When you ship your cylinders to us, they should be prepped and packed carefully to prevent damage and avoid fluid leakage. Make sure to include your contact information in the box with your cylinders.

  • If we advance-shipped cylinders to you, please include the core deposit paperwork in the box with your core return.
  • If you plan to exchange/swap your cylinders, please note that on your paperwork.

When we receive your cylinders:

We perform a detailed inspection when we receive and unpack your cylinders. We look for missing parts, physical damage such as bent rods, drilled holes, scrapes, dents, rust and pitting, or any other alterations to the original factory cylinders. If your cylinders are free of damage and all the parts are intact, we begin the repair the same day that we receive your cylinders. If we find any damage during our inspection process, we will call you to discuss the damage before we start any work on your cylinders. Often times we can still repair your damaged cylinders but additional costs will apply based on the extent of the damage.

Core deposit and core returns for advanced shipped cylinders:

We charge a refundable core charge/core deposit on all advance-shipped rebuilt cylinders. The “core” is the part of the cylinder that we rebuild/remanufacture to bring back to original function and specifications. When you purchase a rebuilt cylinder from our inventory, we expect you to send your original cylinder back to us as a good, “re-buildable” core.

When you return your core, we inspect it thoroughly upon receipt. Your core deposit will be refunded in full if your core(s) passes inspection. If your core(s) is damaged in any way, we will contact you with the details. Any additional work and charges associated with rebuilding your core will be deducted from your core refund.
