The kit is very high quality. I did it in my 1995 c1500. I was confused about the fittings so I emailed Spencer and got nothing but positive and straight forward answers. This guy is really great . From the products and kits he makes to the customer service he gives out. If I buy another trans kit I will 100 percent be buying it from here!
The parts are all top quality, especially the new notched hood support looks factory. Ease of install is very easy and straightforward. (your transmission will thank you)
the packaging of everything in the kit is probably the best I’ve seen, I greatly appreciate that!!
Most importantly the customer service is awesome!
Highly recommend this kit & KLOC Fab.
Called with questions prior to ordering and the customer was awesome!
Products came well packaged and very prompt..
Highly recommend Kloc Fabrication
Everything fit perfectly, highly recommended for a bolt in kit with no guess work.
96' OBS LS swap (4L60E trans cooler with center bracket kit) very impressed with their customer service. The part I needed was on backorder, they communicated very well with updates and shipment dates. I highly recommend this company. 5 star service.
