4x4 Parts

Looking for parts? We can help. We have access to parts from a wide variety of distributors.


Our Services:

Lift kits

Bigger is better right?  Not necessarily!  But how much bigger?  What size tires do you want to run?  Will they rub?  Tons of questions come up when it comes to lifts so when you’re looking for the right answers it’s best to talk to a professional.  Let Hillside 4×4 help you get the right answers.  We will only recommend quality brands such as Rock Krawler, Evo Manufacturing, Synergy, Teraflex, Rubicon Express, and more.

Gears and lockers

You just put the new lift, wheels, and tires on and now you’re wondering where all your power went.  When you put the larger tires on, it now takes more power to turn those big shoes.  You’ll also notice a drop in MPG.  This all happens because the engine is no longer running in its power range that it was designed to.  The solution to this is to re-gear your vehicle with the right gear ratio for the tire size.  Let Hillside help you determine what the best options are for re-gearing your rig.

Armor installs

When you’re out on the trails, stock bumpers just don’t cut it.  From bumping into rocks or obstacles, to stopping the Prius that crashes into the back of you,  Bumpers, fenders, and armor make a huge difference on how your jeep survives life at the mall.  We can outfit your Jeep or truck to protect itself from these dangers in any way you see fit.  

Tires and wheels

Hillside can give you some recommends on the best tires and wheels to run regardless of stock or modified vehicles.
