RedSquare Posted January 14, 2011 Report Share Posted January 14, 2011 Hello Following KYB's compatibility guide, I ordered a set of MonoMax struts for the front and rear of my 720. The fronts bolt on with no problem, but the rears don't. The ones that came in the mail have a 5/8" ID rubber bushing while my truck has standard 3/8" / 10mm OD stem (bayonet) mount. Looking under a co-worker D21 Hardbody, I saw that it uses the rubber bushing type (like what came in the mail). Can I swap my 720's the lower shock/leaf spring mounts to the bushing/hardbody type without any problems? Will it affect ride height? What came in the mail... What's on the rear of the 720 (center white ones)... Quote Link to comment
datzenmike Posted January 14, 2011 Report Share Posted January 14, 2011 If both extend and compress the same distance then you could I guess. Lot of bother to 'make them fit'. I'd return them for the correct ones. I assume the red ones in the picture are the fronts. I see that you call your 720 an '86 and that's fine. They were produced until 10 '85 or roughly 3 months into the '86 model year. The next gen truck the D-21 Hardbody followed in November and is considered an '86 1/2 model. When ordering your shocks it may have been set up to infer that you had an '86 Hardbody. Return them and order for an '85 and you should get the correct ones. . Quote Link to comment
Charlie69 Posted January 14, 2011 Report Share Posted January 14, 2011 The red shocks look like fronts for 520 521 620 & 720 trucks. Quote Link to comment
RedSquare Posted January 14, 2011 Author Report Share Posted January 14, 2011 Yeah, the reds are fronts. I wrongly took a picture of them together during my supposed build thread. Currently I'm waiting on KYB's response to my seller and if it takes to long, i'm just gonna take a trip to the junkyard for a D21 mount. Quote Link to comment
datzenmike Posted January 14, 2011 Report Share Posted January 14, 2011 To answer your last question, no. Shocks do not set height, that is a function of vehicle weight and the springs supporting it. Quote Link to comment
yello620 Posted January 14, 2011 Report Share Posted January 14, 2011 I would be trying to get the newer mounting style on the rear lower mounts from the hardbody. I personally hate the stem style lower mounts. Good Luck Quote Link to comment
RedSquare Posted January 14, 2011 Author Report Share Posted January 14, 2011 Cool. Pulled the mounts from the junkyard, and all holes lineup. After some paint tonight, I'll throw'em on in the morning. Quote Link to comment
