'62 Cat KYB Shock Questions
I know the shock topic has been discussed many times but I have a few open issues that need your help. ‘62 Cat will be on standard height springs & tires so shock travel should be near stock. From what I have been able to read from past posts:
1) Fronts have been listed as either KG 4515 or KG 4550. KYB website lists the dimension differences but either should work. What have you used? 2) Rear choice seems to be only KG 5438 that has 5/8” rubber bushings on either end. I will need to install a sleeve for the upper mount, however McMaster Carr & MSC do not have anything 5/8” OD x 7/16” ID x 1 3/4” long. Any ideas as I do not have OE shocks to reuse those sleeves? Otherwise will have to look for 3/8” schedule 40 pipe or 5/8” tubing stock to cut to length. EBAY metal vendor has something that looks promising. Well aware of the other shock choices but the KYB Gas-A-Just looks like a good cost effective & performance-based product for my vehicle. |

Yep, I too went through the shock carousel for my 1962 Catalina the fronts were easy and made a pretty big difference, as I found out the right rear and left front shocks were blown out and there is a bridge that we call the sailing sailing bridge as it is quite wavy going over it at speed in a regular car and with the Catalina it started bucking and I would have to reduce my speed to cross it.
Anyway, I used the KYB-Gas shocks as they were Mono-tube, On the Front, I used the KYB-4550 by the numbers are Extended 13.54" Compressed 9.25" 4.29 Stroke. other options were the KG-4515. and on the rear-end the old shocks on the car were a Gaberial # 733625 that crosses over to a Monroe 33082 I didn't know if these were the correct shocks bit this is what I have found out. I wanted the same shock manufacturer on the front and the back so I did some research and found 4 options KG-4012 KG-5426 KG-5507 KG-5438 I used the KG-4012 as the numbers of 21.0" extended 12.9" Compressed with a 7.89" stroke with the shorter compressed at 12.9" made sense to me as my car is a little lower with 58-year-old springs. I hope this helps with different options for your 62 Cat shocks!

Thanks much for the feedback. After spending way too much time researching sway bars & shocks for this car I went with the Bilsteins from RCD. These have been modified with the correct mounting brackets & bushings for the '62. PST/Kanter was having a sale over the holidays so that helped to seal the deal. Handling is so much better!
