Are stiffer springs something we could do ourselves? I emailed FF a while back and they said they don't work on truck boxes...
Most trucks have Saginaw boxes... There are plenty of rebuilders that will mod a Saginaw box as they are commonly used in GM products....
As far as someone changing out the reaction springs themselves it can be done but between the seal kit, the special tools & the fact I've done three of them & all three leaked I'll just give firm feel the money...
