I couldn't really find any reviews or info for the 4 inch belltech lift kit online. It seemed too good to be true as it's priced under $1200 CAD. Height Adjustable front struts, UCA's, rear shocks, rear blocks, and a skid plate. I decided to take a gamble and get this kit over bilstein and fox. I am extremely impressed. Belltech claims this is the best riding lift kit and I have to agree. I had bilstein 5100 on my f150 and I'd have to say I prefer belltech both on and off road. Significant improvement over the OEM Ranchos.
With the Ranchos I had quite a bit of body roll when cornering. The steering felt unresponsive and wallowy. When I hit a bump, dip, railroad tracks or any imperfection in the road it felt like my truck got launched into the stratosphere and it would bounce several times before stabilizing. That has all been corrected with the belltech shocks. No body roll, steering feels tight and responsive. The compression and rebound are tuned perfectly for these trucks. The ride is quite a bit firmer but it stays controlled and composed and does an incredible job at smoothing out any imperfection.
Offroad I am equally as impressed as the on road performance. I did a test drive up a decommissioned logging road that hasn't been maintained in years. The ride felt smooth, controlled, and handled large pot holes with ease. with the stock suspension and even the bilstein 5100 on my previous truck, I had quite a bit of chatter if I picked up speed. Didn't get any chatter with the belltech kit.
The UCA's are quite beefy and even have grease zerks which is typically only found on higher end kits. No loss in turning radius. The skid plate is nothing fancy but does what it's intended to do.
I highly recommend this kit if you're looking for a 4 or 6 inch lift. At the price they're asking it may even be worth it to get this kit over a level. I am running 285/75/17 on 0 offset wheels with no rub so you could fit a 34" tire.
