Whats the difference between the 5" springs and the Heavy Duty 5" springs? And do the HD ones affect the flex of the springs?

[toyomr285]

Are you talking about trail gears springs? If you are you may not get a answer.  But I think those HD springs are for trucks equipped with v8.

the HDz are for prople running heavyer engines

[BHT12 [OP]]

Alright that makes sense thanks i was just curious

[Goldrush]

they are also not for people with the heavier engines but for a heavier truck all together

[Goldrush]

like a second gen runner rather than a 1st gen

[junya92toy]

or if you haul a lot of weight in your truck.

[Goldrush]

true.

actually if u read TGs site.. it tells you what they are for and the difference....

Now our front 5" springs are available in a heavy-duty version with a 25% higher spring rate. We have added a 7th leaf and readjusted the length of the leaves to match. If you are running a larger v6 or v8 motor you will appreciate the extra weight carrying capacity of these springs.
