The problem might be that they are tightening the nuts and bolts with the weight off the tires. One of the big things people always tell you over on the liberty forum is to put the bolts in on the UCA's with the nuts on loosely, then put the weigh on the front end, then tighten the nuts to spec.

They should fit the 14's too then since they are the same, but the spring rates or dampening might be a little off due to the extra weight.

many of the other coilover kits list as 14-18.

I wonder how much of a softer ride these will have with the 500 lb rated spring compared to the halo's which are 700lb.

Any noise from the rear 5160s?

Skeets

the ride is excellent with no body roll on the vehicle it's a truck. I wouldn't call it soft, the original OEM ride was soft and mushy. The trucks ride is firm but controlled even on washboard roads. I was told the spring rate was around 600 lbs. If it was 500 which was close to OEM springs why not just market them like the 5100's. I've had 5100's on F150's and they're definitely not 5100 and when you feel the difference in performance with the vehicle you'll see exactly why they made this setup. It works on and off road, and your vehicle comes alive. You'll also see why they went to the expense of engineering the shock and the spring to work together like some other brands do.

The 5160 don't make any noise and haven't made any noise, on any Toyota I've ridden in with them either. There's some good video's on the internet on them to help you make a choice. They drove some trucks hundreds of miles to SEMA with different Bilstein upgraded products off road to test the product and used the trucks for exhibits at the show ( they were Toyotas). I've driven a few hundred miles with them off road and for my application they work just fine. Are they Halo's no but they're Bilsteins and let's not look past the fact they manufacture and build many different setups for on and off road applications. They're not for everyone but the again neither are Halos, Fox or Kings. They are however, a great setup for the guy looking to improve the ride and handling on his F150 on and off road if he wants more than the 5100 at a more reasonable price point.

I called them yesterday and they confirmed that it is 500, I would guess most of the magic happens in the valving.

Skeets

interesting in that they sell the 8125 w/o springs which is a more expensive shock and most use their OEM springs in that application but have the option to use other springs, for different applications. Fox markets their product for us with with springs, king and Halo does too so that spring rate along with the valving as you mentioned must have some importance in making the valving work the way they intended. They work fine for me as engineered so I'm happy no matter what spring rate they are, others may find they need a different spring rate for their application but the majority of guys on here simply won't. Thanks for the information.

I pulled a 27 foot travel trailer for a friend and the shocks were fine in that towing application. Pulling my 20 ft Ranger boat doesn't pose any issues either so for loads suited to the truck they seem to be fine..

I was originally looking at the halo's but there were a few guys claiming the ride was a bit rough for a daily driver so that's why the bilstein 6112 caught my eye with the lighter spring rate. Maybe there is a difference or maybe not.

I would imagine that maybe Halo is running a little less compression dampening on the shock so that the sharp hits are still absorbed well, but the stiffer spring would help with slower movements like body roll and what not. This is something people do with their mountain bike shocks, run less air pressure(spring rate) for better small bump compliance, but turn up the compression dampening so that you can still absorb the big/fast hits without blowing through the travel.

Problem is that makes the bike more floaty, so you wouldnt want that if you were riding on the road.

Maybe a dumb question but can you use the 6112's with a standard 6" lift to obtain a 8" lift?
