880joe Posted August 8, 2017 Share Posted August 8, 2017 Does anybody make a 44000lb replacement spring for taper leaf spring suspension. I was told that there was an aftermarket one available but haven't been able to find any Quote Link to comment Share on other sites More sharing options...
Timmyb Posted August 10, 2017 Share Posted August 10, 2017 Triangle is one brand I've seen. And Donovan springs. https://www.donovanspring.com/mack-suspension-parts.html Quote Link to comment Share on other sites More sharing options...
MHfred Posted August 10, 2017 Share Posted August 10, 2017 Triangle, in Dubois, PA, supplied me a replacement leaf for 1954 White. I was amazed. Quote Link to comment Share on other sites More sharing options...

Freightrain Posted August 10, 2017 Share Posted August 10, 2017 (edited) They show some front springs also. I wonder if they have tapered leaf for the front of a B model? Wouldn't that just be a FINE upgrade over that monster spring pack? I was able to blow up the pictures and doesn't look like anything but stock springs. Ugh.

880joe Posted August 10, 2017 Author Share Posted August 10, 2017 I have st34 suspension I believe. I got ahold of Donovan Spring and pretty sure they have what I need. Thanks for the response and help Quote Link to comment Share on other sites More sharing options...
kscarbel2 Posted August 12, 2017 Share Posted August 12, 2017 You can upgrade 34,000lb Mack taperleaf (parabolic) springs to 38,000 taperleaf (4QK3368AM to 4QK3369AM). But you wouldn't want 44,000 capacity taperleaf springs (if even aftermarket available) on 34,000 capacity Mack (ST34) axles. Quote Link to comment Share on other sites More sharing options...

Thanks for the response and help Glad we could be of assistance. Can I ask how you like the taper leaf? Can you compare it to a standard camelback?

880joe Posted August 13, 2017 Author Share Posted August 13, 2017 I only had the taper leaf on a couple of road trucks they seemed to ride pretty good and had good articulation in the truck stop parking lot pot holes. The ride is much better than the camel backs that I have had. 1 Quote Link to comment Share on other sites More sharing options...
