Just another annual update. My Street Ryde/ProSlip 52 Chevy truck is heading into it’s fourth winter on the road. After three years and 30,000 miles, your suspension kits have held up perfectly: I’ve not had a lick of trouble. The tires look great and I’ve only had it aligned once, when I put it on the road. I haven’t had to touch the brakes (GM Big Brakes) either.

I’m glad I installed this suspension. It has made my truck a comfortable daily driver. All weather, all road conditions, any length trip I can tackle with no concern. I was talking with a guy who has a stock 50 and he said a hundred mile trip is a chore that really beats him up. No thanks – I’ll take my Street Ryde any day.

My website has moved to its own domain, www.chuckthetruck.com, for folks who are thinking about doing their own install.

Thanks again for the fantastic products!
