Has anybody installed one of these in a Frontier? Looking to maybe purchasing one but want to get feedback before I spend the $$$

4x4s have a two speed transfer case that more than doubles the power to the wheels. The stuck 4x4s you drove past were probably driven by little girls from Florida and their 4x4s didn't have ATC traction controls or LSDs (Limited Slip Differentuals. Normal 'Two Wheel Drive' vehicles really only have one wheel powered on slippery surfaces and the one with the least traction gets all the power! The 4x4 doubles the traction but traction controls are needed for all wheels to drive on slippery surfaces.

There are many misconceptions about the drive lines in modern vehicles like AWD, FWD, RWD, on demand four wheel drive, electronic and hydraulic wheel driving

units. IMHO a ‘real’ Four Wheel Drive should have a two speed transfer case that can increase the ‘crawl ratio‘. Increasing the crawl ratio does two important things for the truck, (A) It increases the effective power to the wheels for steep climbing and traveling through mud. (B) And, more importantly, it aids in the ability of the engine to act as a speed brake to prevent over heating and loss of the hydraulic brakes I.e. the ability to STOP on steep down hill grades!

So a lot of the 4x4 system is about gear ratios for power and four wheel drive for traction. Mud and deep snow will require more axle ground clearance than stock trucks have.

With all due respect...

I've never seen a Toyota Tercel or any other AWD Full Size Vehicle on trails like the one pictured below.

Have a good one.. Don S..

please check out the opening page of N4W

http://www.nissan4wheelers.com/n4wheel.html

The site and name is mainly about 4x4s and cover all Nissan vehicles.

I am a member and visit the site every day. I have been eyeball to eyeball with some of these fine people. Perhaps one needs to be a member for full benifits.

Have a good one and thanks for your interest and many good posts!!!
