<font face="arial black">Ed Price, I believe, did some testing a ways back in relation to the Surplus Center snowmobile shocks.. Here's a clip of the results, Ken:</font> <div class="MsoNormal" style="MARGIN: 0in 0in 0pt"><tt><span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Courier New'"><font face="courier">I finally got around to measuring the spring rate for my Amphi front coil springs. I also measured the rate for a new Maeco PK22K1 coil-over shock (available from Surplus Center at $20 each). Here's the results:</font></span></tt><span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Courier New'">

</span><tt><span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Courier New'"><font face="courier">I conclude that one of my front springs is a bit weaker than the other. I also see that the Maeco is very similar to the original Amphi springs. So, I'm going to follow Ken Chambers advice and use the pair of new Maecos on the front of my Amphi.</font></span></tt><span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Courier New'">

</span><tt><span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Courier New'"><font face="courier">BTW, the Amphi shocks have an extended length of 13" and a stroke of 3.5". The Maeco shock has an extended length of 13.25", and a stroke of 3.5". This is so close as to be identical.</font></span></tt> <div class="MsoNormal" style="MARGIN:

All of the movement was coming from the tires. Even w/ two of us pulling on the bumper we couldn't get spring flex. With the "topping" I has w/ the ALDAN shocks and original springs, it makes me wonder if the original Amphicar springs are a bit too strong for the vehicle weight.</font></span></tt> <div class="MsoNormal" style="MARGIN: 0in 0in 0pt"><tt><span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Courier New'"><font face="arial black"></font></span></tt> <div class="MsoNormal" style="MARGIN: 0in 0in 0pt"><tt><span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Courier New'"><font face="Arial Black">--Larry</font></span></tt> <div class="MsoNormal" style="MARGIN: 0in 0in 0pt"><tt><span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Courier New'"></span></tt>
