Engine Guards
About Engine Guards
Engine guards protect the engine's side cases and the area around the countershaft sprocket from rocks, ruts and impacts. On a sport quad, a hard hit to an engine case can crack it and leak oil, which makes these guards a common upgrade. The listings here are case savers and case guards for machines such as the Yamaha Warrior and Raptor 700R, the Suzuki LT-Z400 and several Honda models.
Case savers are listed in several forms, including poly (plastic) versions and ones in black, red, blue or polished finishes. Some are listed as a case saver with sprocket cover in one piece. Match the part to your machine and year, because the case shape and the mounting points vary. Check each description for the material, since poly guards flex on impact while metal ones are stiffer, and choose according to how hard you ride. Fit it according to the maker's instructions, and use thread locker only if they say so.
Brands in this category are Pro Design, Moose Offroad and T.M. Designworks. Pick your machine in the Ride Finder at the top of the page. For more protection, see Skid Plates, Sliders & Spools, Frame & Crash Protectors and Radiator & Oil Cooler Guards, all part of Guards & Protection.
FAQs on case savers and engine guards
What is a case saver?
A case saver is a guard that covers part of the engine's side case, usually near the countershaft sprocket, to protect it from rocks, a thrown chain and impacts. It is a low-cost part that can prevent a cracked case.
Do I need an engine guard if I already have a skid plate?
They protect different areas. A skid plate covers the underside, while a case saver or case guard covers the side of the engine. If you ride rocky or rutted terrain, many riders fit both, so choose by where the damage happens on your machine.
Are poly or metal case savers better?
Poly guards are lighter and can flex on impact, while metal ones are stiffer and may last longer under heavy abuse. Neither is best for every rider. Choose by terrain and by how you ride, and check the listing for the material.
Will a case saver fit my machine?
Case savers are made for a machine and year, because case shapes and mounting points vary. Listings name models such as the Raptor or the LT-Z400. If your model is not named, do not assume it fits.
How do I install a case saver?
Most replace or attach to existing fasteners on the engine side case. Follow the maker's instructions, tighten fasteners to the specified torque, and check them after your first ride. Use thread locker only where the instructions call for it.
