59-60 Buick Parts

If you plan on upgrading your 59-60 Buick with our 4L80E and LS swap kit you will also want to grab one of these. The stock K-member hoop is not quite big enough to clear the modern style drive shaft so you will need to cut out a section of your existing K-member and weld this bad boy in. It will add all the strength back and then some. It comes with a drop out, bolt in bottom plate which makes servicing the trans and driveshaft much easier. You could also use this drop out perch as an exhaust hanger mount if you wanted. This loop also serves as the exhaust pass through so that your exhaust and transmission no longer have to grab the ground or limit how low you can go!

This heavy-duty crossmember is built from 3/16” steel and precision-engineered using 3D scan data to maximize exhaust clearance, simplify installation, and maintain proper floor clearance. Each unit is laser cut, CNC bent, and TIG welded in Texas—100% Made in the USA. Includes locating templates and step-by-step instructions, plus a video QR code for guided installation. Installation requires drilling four new 3/8” holes into the factory “C” section of your original K-frame. Key Features: Precision laser cut and CNC bent for accurate fitment Grade 8 mounting hardware included Designed to work with our 1959–1960 Buick LS engine mounts Optimized placement eliminates the need to modify the transmission tunnel Additional Notes: Factory driveshaft hoop will require minor clearancing Compatible with our optional 2-piece driveline setup

Johnsons Radiator for 1959 Buick Lesabre, Invicta, or Electra all models with LS Swap (or LT) in mind. This Radiator was designed in collaboration with Hammer Fab and Johnsons Radiator Works specifically for LS/LT swaps. It bolts directly into the stock location and has the correct inlet and outlet port sizes for modern LS/LT hookup. It is designed to accept at least 700HP heat demands. We recommend installing a separate transmission cooler which is why this one does not come with a built in cooler. Accepts a modern billet or standard radiator cap and has overflow tube. Also has a petcock drain at the bottom. It you plan on installing our front suspension with splined sway bar this will clear and fit perfectly! Made in USA. Place your order here and we will take care of the rest. Please allow 2-4 weeks for production. These are made to order and will be drop shipped to you. 40% Increased Cooling Efficiency vs. Aluminum Our BIGGEST questions - Why choose JRW? And why copper/brass? To start, copper has a 40% MORE thermal cooling efficiency over aluminum. Paired with a proprietary serpentine fin design we use - designed by Walker Radiator - with over 600,000 louvers in each radiator. This eliminates air boundary build up inside the core. Vehicles from the 1930’s have up to 40% less core size than today’s cars/trucks. Majority of todays cars/trucks are equipped with 400-500hp, AC condensers, and are daily driven demanding a resilient cooling system - and that’s where we come into play.
