Item received in good condition via UPS in a well-packed box. Everything well packed and no signs of shipping damage – which is good considering its a pretty hefty box to lug around.

Box came delivered in good shape – one of the ends was a little squished only because it was laying against my house when delivered instead of flat on the ground – there wasn’t much space for it to be flat without blocking some of my driveway.

Foam inserts and bubble wrapping made sure the parts came in fully intact and without scratches. The passenger and driver sides were labeled and color-coded and wrapped individually – which means no dings/dents/scratches from lazy packaging.

All of the hardware was included. I’m not showing the brackets for the 2010 or older Jeep JKU’s here since I didn’t need it – but everything was included and nothing missing.

The color-coded packaging and individually wrapped components was a nice thing to have.

Installing the Tyger Auto Star Armor Kit

After everything is unboxed – be sure to read the attached installation worksheet and make sure that you line up the bars with the respective side – one will be marked driver and the other marked passenger side.

Before you start, make sure you have a nice socket set. A socket extender is needed to be able to reach the bolts not just on the front of pinch seam but on the three under mount brackets as well.

Once I had everything unpacked and understood the instructions and bolt dimensions/layout, I put some 5-gallon buckets under my vehicle to help prop up the rails while I finger-tightened the bolts in the pinch seam.

Using five-gallon buckets helped hold the bulk of the weight, I just installed these bolts by hand – make sure you follow the instructions and that the seam bracket is behind the Jeeps pinch seam. I would only finger tighten these for now since you may need to adjust the bar laterally to get the main brackets to line up with tub holes.

At rear section of nerf bar, I just slid the 5-gallon bucket up along the angled part of the nerf bar which gave me enough height & stability to funder tighten the seam bolts.

Once I had the front & rear bolts in, I was able to align the bar so that the three tub mount bolts tightened right up and that was it.  I tightened the three tub bolts and then went back and tightened the six pinch seam bolts.

Bars were Installed!

Installation Guide

Pleasantly surprised at how easy it was to get installed. After reading a ton of reviews of similar products, I was leery of having to cut/drill/bend/machine parts, but I had none of that with this kit. Tons of other kids on many of the large Jeep sites and shopping sites all reported problems/mods/missing alignment or squeaks while driving.

Tyger Auto Jeep Armor Kit Summary

I was pleasantly surprised by the packaging, installation, and appearance of this kit. I’ve seen people order similar kits and have problems with fitment, installation, paint and so much more. I didn’t see anything that would lead me to believe it will be rusted out by next week or have water problems or anything like that. The bolts aligned right up, all the hardware was there, and installation even by myself went quick – just took my time.


Before Tyger Auto Star Armor

I know a lot of people get concerned that you lose some ground clearance. On my vehicle the passenger side has a gas tank skid plate that sits even below these nerf bars so over-all I’m not losing any height/clearance that I can see. I took some undercarriage photos below for you to see.

Looking across vehicle undercarriage – can’t See the passenger side hanging below fuel tank:

Directly below nerf-bars – Parallel to frame – not much height difference if any at all.

Looking across undercarriage from Drivers side – not much if any loss of clearance.  This is a stock JKU suspension with 33″ Ko2 Wheels & 17″ Rims.

I’m happy with the appearance, happy with not losing any clearance and looking forward to taking it out on the trails and reporting back with a field update.

Field Testing Tyger Auto Star Armor

We’ll update this post with a field test of these Tyger Auto Running Boards shortly – Meanwhile safe to note that road handling is great, no new noises/squeaks to report and no change in vehicle behavior – even while driving 75MPH on our toll roads.


Great Price / Value

The Tyger Auto Star Armor TG-JA2J2239B Nerf Bar/Running Board kit is a great value kit. Stronger than the plastic ones that come with factory Jeep and more foot space than the Rubicon Rock Sliders. Easy to install, Great Looks and Great Design.

Good scores across the board, we just wish at this price more running boards would connect to the frame instead of body tub (pinch seams) - however, we'll report back with field experience to see if this is reality or unfounded fear.
