I contacted Wilkinson. Bill explined the NAPA shocks create the most pressure in the closed position. He said they have seen numerous deck lids damaged (bent) and deck lid hinges and pins warped with these shocks due the pressure exerted by the NAPA (Belcamp & Omni shocks). The shock (NAPA style)pressure is maxed in the closed position, exerting a constant amount of pressure on the deck lid.

Bill advised their replacemnt shock has the correct pressure and it is maxed in the open position. He also said he it will not make any difference on the NAPA shocks to have the piston up or down, same pressure.

Bill said a new deck lid is $5,400.00 !

I do not see any reason to screw around trying to save $45-50 and risk damage. I don't believe he would set any sales records for a pair of shocks costing about $90.00. I felt his advice was sincere. His also comes with the hardware.

We all like to save money but the possible consequences do not seem to be worth the risk.

They work great & i don't worry about bending the deck.


IndyDave. I am not sure what the BS is with the less pressure in the closed position on those Detomaso shocks. I put one of those shocks on a press with a scale and the pressure is as indicated below (160 compressed), which is why I hesitate to use them. And these pressure are with cool shocks, you warm them up in a hot engine bay and it is much more. I hear 110 lb max is what it will take to not bend the decklid on shocks over time. If I buy them I wonder if they would guarantee decklid replacement, as that is where the rubber meets the road. Don't take my word for it, anyone buying them just put it on a press with a scale before you put it on your car and read what it says as you compress them.

Here are the pressure measurements I got on the Detomaso 18126A measureing one shock:
1/2 to 1" compressed = 120 lb (this is what it took to make it start to compress).
2" to full compression gradually increased from the 120 to 160 near full compression.

I may just end up going with a broom stick and be done with it.
