I removed another brands 4,000rpm governor spring kit and installed TST's 4k kit and am very happy. With the TST springs the truck idles smoother, fuels higher, and no longer experiences governor bounce as it returns to idle. TST's instructions are very detailed and easy to follow. I would recommend these to anyone with a 12 valve.

Great Product works excellent. Only Problem was with Instructions Np. 19 isn't very clear in what exactly to do. The Lower Spring shivs are to be removed and replaced with the ones that come with the kit. You will eventually figure it out however it is a little bit of a pain if you didn't realize this before you proceeded on with the instilation. Truck runs excellent now, no defueling at all. Can use all 3000 rpm's with no problem. Thanks TST Products for your excellent service and great product.

I installed a set of 40000 rpm governer springs in my 98 12 vavle and I love them. They are easier to install than I thought and they work great. The truck revs really smoothly now. You have to be awake because its so much easier to rev up. Overall I have to say great product the truck fuels really hard now and drives super smooth.
