x2 Same here...5.13s, auto trans running 35s...No overheating issues even with the A/C on...If ever I upgrade my front axles to 44 or 60s will definately run 5.38s (love that added pep)...

 

I've got 5.13's and 33's and I've never even come close to overheating. Go for it, you'll be happy you did!

 

The works done and the credit card is on fire. Got the BFJ (that's a pet acronym for my Jeep... it stands for "Big F&*%ing Jeep". Named so cuz I had a stock TJ and the JK is F&*%ing big)... anyhow... Got the BFJ back from the gear shop. About $2,000 later and I have 5:13's (on front and rear of course) and a Detroit TruTrac in the rear.

I literally drove it straight from the shop to Discount Tire on Linden Road in Flint. They had my Black Rock Vipers and 315/70r17 Goodyear Duratracs ready to go. They do great work.

Here's a pic side by side with the 33x12.5 Dick Cepek F-C II. The 315/70r17 Goodyear Duratracs measure 33.5 inches from the ground to the top under load with 30 psi.



Even with 4.5" of backspacing these dogs rub a tad on the cheap plastic underspoiler up front and on the brake lines! An ever so slight and gentle nudge on the brake line moves them outta harms way.



A couple minutes in the Discount Tire lot doing a bit of reprogramming with the SuperChips and I made my way home for a photoshoot with my cell phone.



The spare is riding on the stock carrier for now. Probably until it breaks...



My wife thinks I should name the Jeep "MLC" for Mid-Life Crisis. I like BFJ better.

 

I would prefer
5.13's
