GMRCK25 Suspension Enhancement System by Timbren Review

Didn't fit my 2005 Silverado 1500 perfectly. I had to drill some new holes in the bracket. I think my springs sagged so I trimmed the rubber blocks to give the suspension some room to ride over small bumps. I probably should have taken the bags.

These things are amazing! Have a 5,000 pound camper on a fifth wheel and it has no sag in the rear. However, they are not a replacement for worn springs. Removing your springs will make your car stiffer as it will hit them a lot harder.

These were added to our 2000 k2500 single cab. Sometimes we tow our tractor, hay or pickup onto our 6 ton trailer. Before that, we were bad at shooting from a slingshot. reinforced back. Saved it from sagging as described. I also screwed an extra distance to it. Fits about 1/2 inch of the case. With no load it still runs perfectly.

Very handy in the back of my 2009 Chevy 2500HD during the winter months when I have a 5 foot grinder. The grinder weighs around 500 pounds empty (according to the manufacturer) and the fenders barely touch the axle. So in the warmer months when I ran out of a rear grinder I removed the fenders. Simply jack up the truck to hang the axle and simply remove the fender leaving the bracket attached to the frame.

Very easy installation. Even used old equipment. You only have to lift the frame to make room to access the old bumper blocks. I did without the supplied spacer because I wanted to relieve the gap between the spring and the axle. I loaded about 400 pounds in my 1997 GMC Sierra and the spring made contact with the axle so there was no play. I took it for a test ride, it works fine (although it rides a little harder). I then hooked up my 6,000 lb camper trailer and with the cargo bars/roll bars…

Based on other timbral spring reviews I was led to believe that I could fit these timbral springs instead of replacing my worn rear leaf springs in my 1966 Chevrolet K1500 substitute. I made a mistake, but that doesn't make it bad. I easily installed the rubber springs in less than an hour and tested them for several days and found them to be very resilient. I called Timbren and they told me to remove the 1" washer that came with the springs, which I did in about 20 minutes. This eliminated 50%
