This is the non-reverse or external reverse engine that fits most pre-2010 buggies with either no reverse (such as the Yerf Dog Spiderbox or Tomberlin Crossfire) or an external reverse gear box as with all other pre-2010 buggies with the exception of the Crossfire 150R.  Call and speak with our technicians at 434 447 4870 to confirm your engine.

We bore out the case of your new engine and install a 62mm big bore kit increasing your piston and cylinder size from 54.5mm to 62mm, adding an additional estimated 10% horsepower. See the difference with the GIF below. We also upgrade your transmission installing the stage 1 transmission system. You can also upgrade to the Stage 2 transmission system, including a high stall clutch and a performance variator, giving you a full high performance transmission system. See item 178. https://www.buggydepot.com/product/178/stage-2-drivetrain-upgrade-cvt-system.html


 

IS THIS YOU ROLLING BACK DOWN THE HILL?

GET THE POWER YOU NEED!


 

The clip above shows hill climbing ability of our flagship 184cc GY6 engine (stroked, big bore, and high compression). (This is NOT the same engine being sold in this listing) The purpose of this comparison is to showcase our ability to radically (and reliably) improve the performance of the GY6 engine. The 175cc will make it up this same hill, unlike the 150cc.

 



We start with your base new engine, disassemble, bore out your case, and install the larger more powerful 62 mm big bore piston and cylinder. We then fully reassemble and fully test your new engine before shipping to you.

PROFESSIONALLY MACHINED BIG BORE PREP


 

 

GUARANTEED TRUE 175CC


Don't be tricked by "200cc" and "180cc" engines on the internet that are actually 171cc. Our engine uses a high quality 62mm piston for exactly 174.5cc actual displacement.

 

 


 

Arrives with Large Valves Installed
The large 27mm/24mm valves allow the engine to breathe better at high RPM, allowing for higher top speeds. This is a very noticeable improvement if your original engine came with the smaller 24/23 valves.

 



 

Also includes STAGE 1 Electrical Upgrade
This engine comes from the factory with our S1 Electrical package, which generates more electrical power for lighting and charging the battery more rapidly.

 



 

Light up the trails!
The high output stator allows you to add extra lights and accessories.
