Engine Rebuild Program

S&S Rebuilds Stock Engines!

InstallCylinders.jpgYou may have heard that Harley-Davidson® no longer offers the factory remanufacturing program, but not to worry! S&S has been offering a similar service for years. We still do, and the S&S Engine Rebuild Program offers a lot of extras the factory didn’t.

S&S Rebuild Program Features

  • Engines are rebuilt with Viola V-Twin® quality service parts
  • Full machine shop service for repairs and performance upgrades
  • 30 day labor and 1 year parts warranty
  • You get the same engine back – keep your original VIN
  • Keep any  performance upgrades you've made - if serviceable
  • If you want your used parts back, just pay the shipping costs

S&S Rebuild Program Benefits

  • Competitive Pricing
  • Dealers! Offer engine rebuild service without tying up your service dept
  • Expert workmanship using premium Viola V-Twin® components


  • Same as Stock Rebuilds
  • Performance Upgrades

Basic Package

We have basic rebuild packages for 1984-’99 Evolution® big twin engines and for 1999-present big twin A and B style engines except CVO engines*. If you want your engine to run just like it did when your bike rolled off the showroom floor and be street legal, the basic package is the one for you.

The basic package includes the automatic replacement of certain wear items such as pistons, valves, valve springs, bearings, etc. and all other parts will be inspected and repaired if needed to ensure that they are within factory specifications. Rebuilds for 1999-later engines automatically include an S&S 3-piece flywheel assembly. If an engine has more than normal wear and tear, and there are unserviceable parts that normally could be reused or rebuilt, the dealer will be contacted to discuss the options.

*CVO engines, as well as vintage big twins not covered by this program, can be rebuilt on a custom basis.  Just contact the S&S® Service & Speed Center®  for a personalized quote. 608-627-0763

How The S&S Engine Rebuild Program Works

The S&S Engine Rebuild Program is available only through participating dealers, and is not available directly to retail customers.

  1. Your dealer will place an order for the desired rebuild package
  2. S&S will send detailed instructions along with a call tag/pick up order.  The call tag allows the dealer to take advantage of S&S’ contracted lower shipping rates. 
  3. As an option S&S can send a shipping crate to ensure that the engine is properly packaged to avoid damage in shipping. Note: S&S is not responsible for shipping damage. We recommend that engines  be insured and packaged properly.
  4. When the engine is received by S&S, it will be disassembled and the parts will be cleaned and inspected. Note: If any part that is normally reusable or is normally refurbished is not serviceable, the dealer will be contacted. These parts can be replaced with S&S or Viola V-Twin parts, but there will be an additional charge since they are not included in the basic package.
  5. Any extra parts or performance products will be added to the order as separate line items. If a Performance Upgrade is chosen over the Basic Rebuild, the difference in price will reflect the difference in product and related labor costs. For example, if an S&S Hot Set Up Kit® is chosen, you won't be charged for rebuilding your stock heads, since they will be replaced with S&S Super Stock® heads. A pretty sweet deal!




All work for Basic Packages and Performance Upgrades will be done by the technicians at the S&S Service and Speed Center in LaCrosse, WI using S&S Proven Performance® parts.

Sending An Engine For Rebuild

Dealers! When sending and engine to S&S for rebuilding, please remove the fuel system, ignition system, charging system, and any engine sensors or electronics. Package the engine securely to prevent damage in shipping. We suggest that an S&S engine carton be used.


  • There is no longer free shipping for this program.
  • At this time S&S does not offer any cosmetic or finishing options. The S&S engine rebuilding program is for functional repair only.
  • Engines receiving the full basic rebuild package have stock performance and are emissions legal.
  • Engines rebuilt with S&S performance products, or performance products installed in the engine when received, are intended only for closed course competition use and are not legal for vehicles used on the street.
