S&S Cycle 510G Standard Gear Drive Cam Chest Kit For Harley Twin Cam (2006–2017)
Complete High-Flow Billet Oiling & Gear-Drive Torque Camshaft Package for Late Twin Cam Engines
Unlock responsive pass-through power and rock-solid timing accuracy on your V-Twin with the S&S Cycle 510G Standard Gear Drive Cam Chest Kit. Precision-engineered for 2006 Dyna models and all 2007 through 2017 Harley-Davidson Twin Cam engines, this all-in-one performance chest pack combines S&S’s famous 510G gear-driven camshafts with a blueprinted billet oil pump, high-flow cam support plate, and premium valve train components.
The 510G cam profile is a legendary bolt-in performance grind engineered to boost mid-to-high RPM torque and horsepower across 88ci, 96ci, and 103ci engines. Converting to gear drive completely eliminates problematic factory chain tensioners and timing chain whip, while S&S’s high-flow oiling system dramatically increases oil circulation and scavenge capacity to eliminate engine sumping.

Engine Dynamics & Gear Drive Performance
### The 510G Mid-Range Power & Gear Drive Advantage
The S&S 510G cam profile is specifically tailored for lighter bikes and highway touring cruising where top-end acceleration and mid-range pass-through torque matter most. By switching from chain drive to outer and inner gear drive sets, you eliminate the friction, wear debris, and timing drag associated with factory tensioner shoes. The result is instant throttle response and consistent valve train operation at elevated operating temperatures.

Step-by-Step DIY Installation Overview
Installing an S&S Cam Chest Kit is an advanced mechanical upgrade. Estimated installation time: 3 to 4 hours using standard engine shop tools.
### Required Tools
- 3/8″ Drive Torque Wrench (in-lbs and ft-lbs)
- Dial Indicator with Magnetic Base (for measuring crankshaft runout and backlash)
- Cam Gear Locking Tool / Press Setup
- Quick-EE Pushrod bolt cutters (if removing solid stock pushrods)
- Assembly lube, engine oil, and replacement gaskets
### Step 1: Disassembly & Pinion Shaft Runout Measurement
Safely secure the motorcycle, drain engine oil, and remove the outer cam cover, floorboards, and exhaust headers. Cut or remove original factory pushrods using Quick-EE instructions. Extract the factory cam plate and oil pump. Place a dial indicator on the end of the crankshaft pinion shaft and rotate the motor to measure total indicated runout (TIR). Runout must be .003″ or less to run gear-driven camshafts safely.
### Step 2: Assembling the Billet Plate, Cams & Oil Pump
Lube all oil pump gears, pressure relief valves, and internal bearings with clean assembly lube. Install the 510G gear-drive camshafts into the S&S billet cam plate, ensuring timing dots on the inner gears align properly. Press the assembly into the plate and mount the S&S billet oil pump loosely over the pinion shaft before centering and torquing the plate to specification.
### Step 3: Installing Outer Gears, Lifters & Pushrods
Press outer drive gears onto the camshaft and pinion shaft, aligning outer timing marks. Verify gear backlash using a dial indicator. Install the included S&S hydraulic lifters, set Quick-EE adjustable pushrods to pre-load specifications, reattach the outer cam cover with a fresh gasket, fill with fresh oil, and prepare for initial startup and ECU re-tune.
Frequently Asked Questions
### Is an ECU re-tune required after installing the S&S 510G Cam Chest Kit?
Yes. Changing your camshaft profile alters engine airflow and volumetric efficiency. An ECU flash tune (using Dynojet Power Vision, Vance & Hines FP4, or similar tuner) is required to calibrate fuel ratios and ignition timing for proper performance and engine safety.
### What pinion shaft runout limit is required for this gear drive kit?
For gear-drive camshaft setups on Harley Twin Cam engines, crankshaft/pinion shaft runout must be .003″ or less. If your crank runout exceeds .003″, you must either truant/weld your crankshaft or opt for an S&S Chain Drive Cam Chest Kit instead.
